Secure the wiring harnesses by using clamps so that there is no slack However, for any harness which passes to the engine or other vibrating parts of the vehicle, allow some slack within a range that does not allow the engine vibrations to cause the harness to come into contact with any of the surrounding parts, and then secure the harness by using a clamp If any section of a wiring harness interferes with the edge of a part, or a corner, wrap the section of the harness with tape or something similar in order to protect it from damage When installing any of the vehicle parts, be careful not to pinch or damage any of the wiring harnesses 90-2 GENERAL If a burned-out fuse is to be replaced, be sure to use only a fuse of the specified capacity If a fuse a capacity larger than that specified is used, parts may be damaged and the danger of fire also exists 10A The sensors, relays, etc., must never be subjected to strong shocks Do not allow them to fall and not throw them when handling The electronic parts used in the computer, relays, etc are readily damaged by heat If there is a need for service operations that may cause the temperature to exceed 80°C (176°F), remove the electronic parts beforehand Loose connectors could troubles Make sure that the connectors are connected securely 15A GENERAL When disconnecting a connector, be sure to pull only the connector, not the harness Disconnect connectors which have catches by pressing in the direction indicated by the arrows in the illustration Connect connectors which have catches by inserting the connectors until a “snap” noise is heard When using a circuit tester to perform continuity or voltage checks on connector terminals, insert the test probe from the harness side If the connector is a sealed connector, insert the test probe in through the hole in the rubber cap for the electrical wires, being careful not to damage the insulation of the wires; continue to insert the test probe until it contacts the terminal 90-4 LOCATION OF SWITCHES AND RELAYS LOCATION OF SWITCHES AND RELAYS ENGINE COMPARTMENT SWITCHES AND RELAY (3, 4, DOOR) 90-5 LOCATION OF SWITCHES AND RELAYS DASH AND STEERING COLUMN SWITCHES AND RELAYS (3, 4, DOOR) MULTIFUNCTION SWITCH 90-6 LOCATION OF SWITCHES AND RELAYS PASSENGER AND LUGGAGE COMPARTMENT SWITCHES AND RELAYS 90-7 IGNITION SWITCH IGNITION SWITCH INSPECTION Inspect the switch continuity between terminals If continuity is not as specified, replace the switch 90-8 FUSES FUSES FUSIBLE LINKS Inspection Check for a burnt fusible link with a ohmmeter If a fusible link burns out, there is a short or some other problem in the circuit Carefully determine the cause and correct it before replacing the fusible link NOTE The fusible link will burnt out within 15 seconds if a higher than specified current flows through the circuit IGNITION HEAD LAMP BATTERY ALTERNATOR Fusible link color Pink Pink Pink Yellow Permissible continuous current A 30 30 30 60 Fusing current A 90 90 90 180 FUSE BOX Inspection Be sure there is no play in the fuse holders, and that the holders hold the fuses securely Are fuse capacities for each circuit correct ? Are there any blown fuse ? If a fuse is to be replaced, be sure to use a new fuse of the specified capacity Always determine why the fuse blew first CAUTION Newer use a fuse of higher capacity than specified 10A 15A FUSES When replacing a fuse, use the puller in the fuse box SCHEMATIC DIAGRAM PASSIVE SEAT BELT TYPE 90-10 ... of the vehicle parts, be careful not to pinch or damage any of the wiring harnesses 9 0-2 GENERAL If a burned-out fuse is to be replaced, be sure to use only a fuse of the specified capacity If... probe until it contacts the terminal 9 0-4 LOCATION OF SWITCHES AND RELAYS LOCATION OF SWITCHES AND RELAYS ENGINE COMPARTMENT SWITCHES AND RELAY (3, 4, DOOR) 9 0-5 LOCATION OF SWITCHES AND RELAYS DASH...
