General Information Honda Cars 2007-2008 Precautions Before servicing any vehicle, please be sure to read all of the following precautions, which deal with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle: Print Never open, service or drain the radiator or cooling system when the engine is hot; serious burns can occur from the steam and hot coolant. Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well-ventilated area. Do not allow fuel spray or vapors to come in contact with a spark, open flame, or excessive heat (a hot drop light, for example). Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion. Refer to the additional fuel system precautions later in this section. Fuel injection systems often remain pressurized, even after the engine has been turned OFF . The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury. Brake fluid often contains polyglycol ethers and polyglycols. Avoid contact with the eyes and wash your hands thoroughly after handling brake fluid. If you do get brake fluid in your eyes, flush your eyes with clean, running water for 15 minutes. If eye irritation persists, or if you have taken brake fluid internally, IMMEDIATELY seek medical assistance. The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer. You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used. All new vehicles are now equipped with an air bag system, often referred to as a Supplemental Restraint System (SRS) or Supplemental Inflatable Restraint (SIR) system. The system must be disabled before performing service on or around system components, steering column, instrument panel components, wiring and sensors. Failure to follow safety and disabling procedures could result in accidental air bag deployment, possible personal injury and unnecessary system repairs. Always wear safety goggles when working with, or around, the air bag system. When carrying a non-deployed air bag, be sure the bag and trim cover are pointed away from your body. When placing a non-deployed air bag on a work surface, always face the bag and trim cover upward, away from the surface. This will reduce the motion of the module if it is accidentally deployed. Refer to the additional air bag system precautions later in this section. Clean, high quality brake fluid from a sealed container is essential to the safe and proper operation of the brake system. You should always buy the correct type of brake fluid for your vehicle. If the brake fluid becomes contaminated, completely flush the system with new fluid. Never reuse any brake fluid. Any brake fluid that is removed from the system should be discarded. Also, do not allow any brake fluid to come in contact with a painted surface; it will damage the paint. Never operate the engine without the proper amount and type of engine oil; doing so WILL result in severe engine damage. Timing belt maintenance is extremely important. Many models utilize an interference-type, non-freewheeling engine. If the timing belt breaks, the valves in the cylinder head may strike the pistons, causing potentially serious (also time-consuming and expensive) engine damage. Refer to the maintenance interval charts for the recommended replacement interval for the timing belt, and to the timing belt section for belt replacement and inspection. Disconnecting the negative battery cable on some vehicles may interfere with the functions of the on-board computer system(s) and may require the computer to undergo a relearning process once the negative battery cable is reconnected. When servicing drum brakes, only disassemble and assemble one side at a time, leaving the remaining side intact for reference. Only an MVAC-trained, EPA-certified automotive technician should service the air conditioning system or its components.

A good rule of thumb is to inspect the drive belts every 15,000 miles (24,000 km) or 12 months (whichever occurs first). On manually adjusted multi-ribbed V-belts, measure the belt tension at a point halfway between the pulleys by pulling or pressing on the belt with a known force and measuring how far the belt moves, referred to as the amount of deflection. Note that -deflection- is not free-play, but the ability of the belt, under actual tension, to stretch slightly and give. The specification for measuring belt tension includes the amount of force applied to the belt, and the amount of defection (movement) the belt should have when the force is applied. The amount of deflection varies depending on whether the belt is new or used. Although the manufacturer markets a specific tool for measuring belt deflection, a fisherman-s spring scale capable of measuring a 22 lb. (98 N) pull and a small ruler can be substituted for this tool. Inspect the belts for the following signs of damage or wear: glazing, cracking, fraying, crumbling or missing chunks. A glazed belt will be slightly brittle and perfectly smooth from slipping, and may exhibit a screeching noise when the engine is suddenly accelerated or first started. A good belt will have a slight texture of fabric visible and the surface should be soft and flexible. Cracks will usually start at the inner edge of a belt and run outward. A belt that is fraying will have the fabric backing de-laminating itself from the belt. A belt that is crumbling or missing chunks will have missing pieces in the crosssection of the belt, sometimes these chunks will be stuck in the pulley groove and not easily seen. All worn or damaged drive belts should be replaced immediately. It is best to replace all drive belts at one time, as a preventive maintenance measure. Although it is generally easier on a component to have the belt too loose than too tight, a loose belt may place a high impact load on a bearing due to the whipping or snapping action of the belt. A belt that is slightly loose may slip, especially when component loads are high. This slippage may be hard to identify. For example, the generator belt may run okay during the day, and slip at night when headlights are turned on. Slipping belts wear quickly not only due to the direct effect of slippage but also because of the heat a slipping belt generates. Extreme slippage may even cause a belt to burn. A very smooth, glazed appearance on the belt's sides, as opposed to the obvious pattern of a fabric cover, indicates that the belt has been slipping. Both multi-ribbed V-belts and serpentine belts can be checked for wear by inspecting the physical condition of the belt. To check belt stretch on multiribbed V-belts, look at the amount of adjustment that remains on the sliding portion of the adjustment bracket, or the threaded portion of the adjustment screw. If the adjustment range has is at its fully extended portion, the belt should be replaced. Serpentine drive belts should be inspected for rib chunking (pieces of the ribs breaking off), severe glazing, frayed cords or other visible damage. Any 1 belt which is missing sections of 2 or more adjacent ribs which are / 2 in. (13mm) or longer must be replaced. You might want to note that serpentine belts do tend to form small cracks across the backing. If the only wear you find is in the form of one or more cracks are across the backing and NOT parallel to the ribs, the belt is still good and does not need to be replaced. To check belt stretch on a serpentine belt, look at the range indicator on the tensioner assembly. The tensioner arm has a pointer that is compared to a small rectangular reference block on the tensioner mounting bracket. If the tensioner pointer has reached or is beyond the edge of the inspection block, the belt has stretched beyond its wear limits and should be replaced.

Attach the belt tension gauge to the belt and measure the tension. Tension should be 99-132 lbs. 2. Follow the gauge manufacturer's instructions. If the belt is worn or damaged, replace it. If the belt needs adjustment, go to see -Adjustment- below.

To check belt stretch on multiribbed V-belts, look at the amount of adjustment that remains on the sliding portion of the adjustment bracket, or the threaded portion of the adjustment screw. If the adjustment range has is at its fully extended portion, the belt should be replaced. Serpentine drive belts should be inspected for rib chunking (pieces of the ribs breaking off), severe glazing, frayed cords or other visible damage. Any 1 1 belt which is missing sections of 2 or more adjacent ribs which are / 2 in. (13mm) or longer must be replaced. You might want to note that serpentine belts do tend to form small cracks across the backing. If the only wear you find is in the form of one or more cracks are across the backing and NOT parallel to the ribs, the belt is still good and does not need to be replaced. To check belt stretch on a serpentine belt, look at the range indicator on the tensioner assembly. The tensioner arm has a pointer that is compared to a small rectangular reference block on the tensioner mounting bracket. If the tensioner pointer has reached or is beyond the edge of the inspection block, the belt has stretched beyond its wear limits and should be replaced.

Attach the belt tension gauge to the belt and measure the tension. Tension should be 99-132 lbs. 2. Follow the gauge manufacturer's instructions. If the belt is worn or damaged, replace it. If the belt needs adjustment, go to see -Adjustment- below.

Back to Top Honda Cars 2007-2008 Precautions Specific to: Print Honda Accord 2007-2008 Honda Civic 2007-2008 Honda S2000 2007-2008 Disconnect and isolate the battery negative cable before beginning any airbag system component diagnosis, testing, removal, or installation procedures. Allow system capacitor to discharge for two minutes before beginning any component service. This will disable the airbag system. Failure to disable the airbag system may result in accidental airbag deployment, personal injury, or death. Do not place an intact undeployed airbag face down on a solid surface. The airbag will propel into the air if accidentally deployed and may result in personal injury or death. When carrying or handling an undeployed airbag, the trim side (face) of the airbag should be pointing towards the body to minimize possibility of injury if accidental deployment occurs. Failure to do this may result in personal injury or death. Replace airbag system components with OEM replacement parts. Substitute parts may appear interchangeable, but internal differences may result in inferior occupant protection. Failure to do so may result in occupant personal injury or death. Wear safety glasses, rubber gloves, and long sleeved clothing when cleaning powder residue from vehicle after an airbag deployment. Powder residue emitted from a deployed airbag can cause skin irritation. Flush affected area with cool water if irritation is experienced. If nasal or throat irritation is experienced, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician. Do not use a replacement airbag that is not in the original packaging. This may result in improper deployment, personal injury, or death. The factory installed fasteners, screws and bolts used to fasten airbag components have a special coating and are specifically designed for the airbag system. Do not use substitute fasteners. Use only original equipment fasteners listed in the parts catalog when fastener replacement is required. During, and following, any child restraint anchor service, due to impact event or vehicle repair, carefully inspect all mounting hardware, tether straps, and anchors for proper installation, operation, or damage. If a child restraint anchor is found damaged in any way, the anchor must be replaced. Failure to do this may result in personal injury or death. Deployed and non-deployed airbags may or may not have live pyrotechnic material within the airbag inflator. Do not dispose of driver/passenger/curtain airbags or seat belt tensioners unless you are sure of complete deployment. Refer to the Hazardous Substance Control System for proper disposal. Dispose of deployed airbags and tensioners consistent with state, provincial, local, and federal regulations. After any airbag component testing or service, do not connect the battery negative cable. Personal injury or death may result if the system test is not performed first. If the vehicle is equipped with the Occupant Classification System (OCS), do not connect the battery negative cable before performing the OCS Verification Test using the scan tool and the appropriate diagnostic information. Personal injury or death may result if the system test is not performed properly. Never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace one, and then perform the Airbag System test before replacing the other. Both the ORC and the OCM store Occupant Classification System (OCS) calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an irreversible fault will be set in both modules and the OCS may malfunction and cause personal injury or death. If equipped with OCS, the Seat Weight Sensor is a sensitive, calibrated unit and must be handled carefully. Do not drop or handle roughly. If dropped or damaged, replace with another sensor. Failure to do so may result in occupant injury or death. If equipped with OCS, the front passenger seat must be handled carefully as well. When removing the seat, be careful when setting on floor not to drop. If dropped, the sensor may be inoperative, could result in occupant injury, or possibly death. If equipped with OCS, when the passenger front seat is on the floor, no one should sit in the front passenger seat. This uneven force may damage the sensing ability of the seat weight sensors. If sat on and damaged, the sensor may be inoperative, could result in occupant injury, or possibly death. Specific to: Honda Fit 2007-2008 Except when performing electrical inspections, always turn the ignition switch OFF, then disconnect the negative cable from the battery, then wait for 3 minutes before starting work. The SRS memory is not erased even if the ignition switch is turned OFF or the battery cables are disconnected from the battery. Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs. Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks, or deformation. Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts connectors. Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury. Do not put objects on the front passenger's airbag. The original audio system has a coded theft protection circuit. Make sure you have the anti-theft codes for the audio system. Before returning the vehicle to the customer, enter the anti-theft codes for the audio system. Set the clock Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering wheel controls, and the horn inoperative. Center the cable reel whenever the following is performed: Installation of the steering wheel Installation of the cable reel Installation of the steering column Other steering-related adjustment or installation Do not disassemble the cable reel. Do not apply grease to the cable reel. If the cable reel shows any signs of damage, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel. Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of an airbag during service, store the removed airbag with the pad surface up. Never put anything on the airbag. To prevent damage to the airbag, keep it away from any oil, grease, detergent, or water. Store the removed airbag on a secure, flat surface away from any high heat source (exceeding 200°F). Never perform electrical inspections to the airbags, such as measuring resistance. Do not position yourself in front of the airbag during removal, inspection, or replacement. Wear safety glasses, rubber gloves, and long sleeved clothing when cleaning powder residue from vehicle after an airbag deployment. Powder residue emitted from a deployed airbag can cause skin irritation. Flush affected area with cool water if irritation is experienced. If nasal or throat irritation is experienced, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician.

If a child restraint anchor is found damaged in any way, the anchor must be replaced. Failure to do this may result in personal injury or death. Deployed and non-deployed airbags may or may not have live pyrotechnic material within the airbag inflator. The side curtain airbag inflator assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and brackets (C). When removing or installing the side curtain airbag inflator assembly, never handle the flexible bag (B). Fig. Never handle the side curtain airbag by the flexible bag (B) portion Do not dispose of driver/passenger/curtain airbags or seat belt tensioners unless you are sure of complete deployment. Refer to the Hazardous Substance Control System for proper disposal. Dispose of deployed airbags and tensioners consistent with state, provincial, local, and federal regulations. After any airbag component testing or service, do not connect the battery negative cable. Personal injury or death may result if the system test is not performed first. Be careful not to bump or impact the SRS unit, front impact sensors, or side impact sensors whenever the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF. During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, front impact sensors, or the side impact sensors. The airbags could accidentally deploy and cause damage or injury. After a collision where the airbags the side airbags, the side curtain airbags, or seat belt tensioners were deployed, many components must be inspected. After a collision where the airbags, the side airbags, or the side curtain airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, and the side impact sensors. If there is any damage, replace the SRS unit and/or the sensors. Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, or front passenger's weight sensors. Turn the ignition switch OFF, disconnect the negative cable from the battery, then wait for 3 minutes before starting installation or replacement of the SRS unit, or disconnecting the connectors from the SRS unit. Be sure the SRS unit, front impact sensors, and side impact sensors are installed securely with the mounting bolts torqued to 7.2 ft. lbs. (9.8 Nm). Do not spill water or oil on the SRS unit or the side impact sensors, and keep them away from dust. Store the SRS unit, front impact sensors, and side impact sensors in a cool (less than 104°F) and dry (less than 80 percent relative humidity, no moisture) area. Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the applicable procedures. Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Be sure to install the harness wires so they do not get pinched or interfere with other parts. Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. Use a U-shaped probe. Do not insert the probe forcibly. Using improper tools could cause an error in inspection due to poor metal-to-metal contact. When cleaning the seats with side airbag, use a damp cloth to clean the seat. Do not soak the seat with liquid, and do not spray steam on the seat. Do not repair a torn or frayed seat-back cover. Replace the seat-back cover. After a collision where the side airbag was deployed, replace the side airbag and seat frame with new parts. If the seat-back cushion is split, it must be replaced. Never put aftermarket accessories on the seat (covers, pads, seat heaters, lights, etc.).

Back to Top Honda Cars 2007-2008 General Information Specific to: Print Honda Accord 2007-2008 Honda Civic 2007-2008 Honda S2000 2007-2008 When conventional brakes are applied in an emergency stop or on ice, one or more wheels may lock. This may result in loss of steering control and vehicle stability. The purpose of the Anti-lock Brake System (ABS) is to prevent lock up when traction is marginal or under heavy braking conditions. This system offers many benefits allowing the driver increased safety and control during braking. Anti-lock braking operates only at speeds above 3 mph (5 km/h). Under normal braking conditions, the ABS functions the same as a standard brake system with a diagonally split master cylinder and conventional vacuum assist. If wheel lock is detected during the brake application, the system will enter anti-lock mode. During anti-lock mode, hydraulic pressure in the four wheel circuits is modulated to prevent any one wheel from locking. Each wheel circuit is designed with a set of electrical valves and hydraulic line to provide modulation, although for vehicle stability, both rear wheel valves receive the same electrical signal. The system can build or reduce pressure at each wheel, depending on signals generated by the Wheel Speed Sensors (WSS) at each wheel and received at the Controller Anti-lock Brake (CAB). Anti-lock Braking Systems (ABS) are available on all Honda models. When this system engages, some audible noise as well as pulses in the brake pedal may occur. Do not be alarmed; this is normal system operation.
