3 01-3 FUSES & RELAYS GENERAL 1. GENERAL INFORMATION 1. Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery cable. - - Turn off all the electrical devices before disconnecting and connecting the negative battery cable. Otherwise, the semiconductor components are subject to be damaged. The volatile memory in electrical devices may be erased. Store them with safe methods. 2. The harnesses that can be touched with a sharp edge or corner should be wrapped with insulating tape to prevent damaging. 3. Carefully handle the wiring harnesses not to damage them during servicing the electric components. 4. If a fuse is blown, be sure to eliminate the cause of problem before installing a new fuse. Use only the fuse of specified rating. Never use a fuse of more than specified rating. It may cause a fire or damage to the electric components.

4 Be careful not to drop or jar the sensors and relays. 6. The electric components used in computer and relays are heat sensitive. If the working temperature will be exceeded 80 C, remove the components before starting the service operation. 7. Loosened connection may cause a malfunction. Always firmly engage the connector. 8. When connecting, push the connector until it sounds "click". 9. When disconnecting, always hold the connector body other than the harness. 10. Disconnect the connector while pressing down the locking tab if applicable. 11. When checking the continuity or voltage, the test probes of the circuit tester should be inserted from harness side (rear of connector). In case of sealed connector, insert the test probe through the cavity in wiring rubber cap. Be careful not to damage the wire insulation. And, the test probe should be insert until its end contacts to the connecter pin. - The circuit tester cannot be used for checking the air bag system. Use only the diagnostic tool (Scanner).

5 01-5 INSPECTION OF CABLES AND WIRES 1. Check the connections for looseness and rust. 2. Check the terminals and wires for corrosion due to electrolyte. 3. Check the circuit for open. 4. Check the wire insulation. Check the cover clothing of the wire for damage, crack and deterioration. 5. Check if any electric continuity can be transferred to other metal components such as vehicle body. 6. Check if the continuity exists on the bolt and vehicle body in ground connection. 7. Check the wire arrangement. 8. Securely fasten the wiring harnesses not to contact to a sharp edge and hot elements (exhaust manifold and pipes). 9. Keep the proper clearance between the wire harness and the moving components such as fan pulley and fan belt. 10. In case of the wiring harnesses connected to the vehicle body and vibrating components such as engine, to avoid damage, do not bind the harnesses without marginal length.
