INSPECTION PROCEDURE

1.INSPECT FUSE (WIP)

  1. Remove the WIP fuse from the instrument panel junction block.

  1. Measure the resistance of the fuse.

    Standard resistance:
    Below 1 Ω


NG
REPLACE FUSE
OK


2.INSPECT IG1 RELAY
B137115E01

  1. Remove the IG1 relay from the instrument panel junction block.

  1. Measure the resistance of the relay.

    Standard resistance:
    Tester Connection
    		Specified Condition
    3 - 5
    		10 kΩ or higher
    Below 1 Ω
    (when battery voltage is applied to terminals 1 and 2)


NG
REPLACE IG1 RELAY
OK


3.CHECK WIRE HARNESS (MOTOR - BATTERY AND BODY GROUND)
E112829E02

  1. Disconnect the A8 motor connector.

  1. Measure the voltage of the wire harness side connector.

    Standard voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    A8-2 (B) - Body ground
    		Ignition switch on (IG)
    		10 to 14 V

  1. Measure the resistance of the wire harness side connector.

    Standard resistance:
    for LHD 
    Tester Connection
    		Specified Condition
    A6-4 (E) - Body ground
    		Below 1 Ω

    for RHD:
    Tester Connection
    		Specified Condition
    A6-5 (E) - Body ground
    		Below 1 Ω


NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK
