Repair and Diagnosis: Service Precautions
Service Precautions:
^ When removing the battery from the vehicle or disconnecting the cable from the battery terminals for inspection or service works on the electric systems, always confirm first that the ignition switch and all the other switches have been turned OFF. Otherwise, the semi-conductor part may be damaged.
^ When disconnecting cables from the battery, be sure to disconnect the one from the negative (-) terminal first and then the other from the positive (+) terminal.
^ Reverse the above order when disconnecting the cables to the battery terminals.
Service Precautions:
^ When disconnecting connectors, never pull the wiring harnesses. Unlock the connector lock first and then pull them apart by holding connectors themselves.
Service Precautions:
^ When connecting connectors, also hold connectors and push them together until they lock securely (a click is heard).
Service Precautions:
^ When installing the wiring harness, fix it with clamps so that no slack is left.
Service Precautions:
^ When installing vehicle parts, be careful so that the wiring harness is not interfered with or caught by any other part.
Service Precautions:
^ To avoid damage to the harness, protect its parts which may contact against a part forming a sharp angle by winding tape or the like around it.
Service Precautions:
^ When replacing a fuse, make sure to use a fuse of the specified capacity. Use of a fuse with a larger capacity will cause damage to the electrical parts and a fire.
Service Precautions:
^ Always be careful not to handle electrical parts (computer, relays, etc.) in a rough manner or drop them.
Service Precautions:
^ When performing a work that produces a heat exceeding 80°C in the vicinity of the electrical parts, remove the heat sensitive electrical part(s) before hand.
Service Precautions:
^ Use care not to expose connectors and electrical parts to water which will be a cause of a trouble.
Service Precautions:
^ When using a tester for checking continuity or measuring voltage, be sure to insert the tester probe from the wire harness side.
