PRECAUTIONS GENERAL PRECAUTIONS The WARNING and CAUTION below describe some general precautions that you should observe when servicing a vehicle. These general precautions apply to many of the service procedures described in this manual, and they will not necessarily be repeated with each procedure to which they apply. WARNING: D Whenever raising a vehicle for service, be sure to follow the instructions under “VEHICLE LIFTING POINTS” on SECTION 0A. D When it is necessary to do service work with the engine running, make sure that the parking brake is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for auto- matic transmission vehicles), Keep hands, hair, clothing, tools, etc. away from the fan and belts when the engine is running. D When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors. D Do not perform service work in areas where combustible materials can come in contact with a hot exhaust system. When working with toxic or flammable materials (such as gasoline and refriger- ant), make sure that the area you work in is well-ventilated. D To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tailpipe, muffler, etc. D New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or used oil. Keep new and used oil and used engine oil filters away from children and pets. Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory ani- mals. Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil, wear a long-sleeve shirt and moisture-proof gloves (such as dish washing gloves) when changing engine oil. If engine oil contacts your skin, wash thoroughly with soap and water. Launder any clothing or rags if wet with oil, recycle or properly dispose of used oil and filters. D Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly during driving, obstructing your view and resulting in an accident. CAUTION: D Before starting any service work, cover fenders, seats and any other parts that are likely to get scratched or stained during servicing. Also, be aware that what you wear (e.g, buttons) may cause damage to the vehicle’s finish. D When performing service to electrical parts that does not require use of battery power, disconnect the negative cable of the battery. GENERAL INFORMATION 0A-3

D When removing the battery, be sure to disconnect the negative cable first and then the positive cable. When reconnect- ing the battery, connect the positive cable first and then the negative cable, and replace the terminal cover. D When removing parts that are to be reused, be sure to keep them arranged in an orderly manner so that they may be reinstalled in the proper order and position. D Whenever you use oil seals, gaskets, packing, O-rings, locking washers, split pins, self-locking nuts, and certain other parts as specified, be sure to use new ones. Also, before installing new gaskets, packing, etc., be sure to remove any residual material from the mating surfaces. D Make sure that all parts used in reassembly are perfectly clean. D When use of a certain type of lubricant, bond or sealant is specified, be sure to use the specified type. “A”: Sealant 99000-31150 D Be sure to use special tools when instructed. Special Tool (A): 09917-98221 (B): 09916-58210 0A-4 GENGERAL INFORMATION

D When disconnecting vacuum hoses, attach a tag describ- ing the correct installation positions so that the hoses can be reinstalled correctly. D After servicing fuel, oil, coolant, vacuum, exhaust or brake systems, check all lines related to the system for leaks. D For vehicles equipped with fuel injection systems, never disconnect the fuel line between the fuel pump and injector without first releasing the fuel pressure, or fuel can be sprayed out under pressure. PRECAUTIONS FOR CATALYTIC CONVERT- ER For vehicles equipped with a catalytic converter, use only un- leaded gasoline and be careful not to let a large amount of un- burned gasoline enter the converter or it can be damaged. – Conduct a spark jump test only when necessary, make it as short as possible, and do not open the throttle. – Conduct engine compression checks within the shortest possible time. – Avoid situations which can result in engine misfire (e.g. starting the engine when the fuel tank is nearly empty.) GENERAL INFORMATION 0A-5

PRECAUTIONS FOR ELECTRICAL CIRCUIT SERVICE D When disconnecting and connecting coupler, make sure to turn ignition switch OFF, or electronic parts may get damaged. D Be careful not to touch the electrical terminals of parts which use microcomputers (e.g. electronic control unit like as ECM, PCM, P/S controller, etc.). The static electricity from your body can damage these parts. D Never connect any tester (voltmeter, ohmmeter, or whatev- er) to electronic control unit when its coupler is discon- nected. Attempt to do it may cause damage to it. D Never connect an ohmmeter to electronic control unit with its coupler connected to it. Attempt to do it may cause damage to electronic control unit and sensors. D Be sure to use a specified voltmeter/ohmmeter. Otherwise, accurate measurements may not be obtained or personal injury may result. If not specified, use a voltmeter with high- impedance (MW/V minimum) or a digital type voltmeter. D When taking measurements at electrical connectors using a tester probe (2), be sure to insert the probe from the wire harness side (backside) of the connector (1). D When connecting meter probe (2) from terminal side of coupler (1) because it can’t be connected from harness side, use extra care not to bend male terminal of coupler of force its female terminal open for connection. In case of such coupler as shown connect probe as shown to avoid opening female terminal. Never connect probe where (3) male terminal is supposed to fit. 0A-6 GENGERAL INFORMATION

D When checking connection of terminals, check its male half for bend and female half for excessive opening and both for locking (looseness), corrosion, dust, etc. D Before measuring voltage to check for electrical system, check to make sure that battery voltage is 11V or higher. Such terminal voltage check at low battery voltage will lead to erroneous diagnosis. ELECTRICAL CIRCUIT INSPECTION PROCEDURE While there are various electrical circuit inspection methods, described here is a general method to check its open and short circuit by using an ohmmeter and a voltmeter. OPEN CIRCUIT CHECK Possible causes for the open circuit are as follows. As the cause is in the connector or terminal in many cases, they need to be checked particularly carefully. D Loose connection of connector D Poor contact of terminal (due to dirt, corrosion or rust on it, poor contact tension, entry of foreign object etc.) D Wire harness being open When checking system circuits including an electronic control unit such as ECM, TCM, ABS control module, etc., it is important to perform careful check, starting with items which are easier to check. 1) Disconnect negative cable from battery. 2) Check each connector at both ends of the circuit being checked for loose connection. Also check lock condition of connector if equipped with connector lock. 1. Check for loose connection Sensor ECM GENERAL INFORMATION 0A-7
