INSPECTION PROCEDURE

1.CHECK HARNESS AND CONNECTOR (4 WHEEL DRIVE CONTROL ECU - DIFFERENTIAL LOCK SHIFT ACTUATOR)

  1. Disconnect the A28 4 wheel drive control ECU connector.

  1. Disconnect the f1 differential lock shift actuator connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    A28-3 (M1) - f1-3
    		Always
    		Below 1 Ω
    A28-9 (M2) - f1-2
    		Always
    		Below 1 Ω


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK
