INSPECTION PROCEDURE

1.CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BODY GROUND)


    C106484E11

  1. Disconnect the L28 connector from the steering lock actuator assembly.

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

    Resistance:
    Tester connection
    (Symbols)
    		Condition
    		Specified condition
    L28-1 (GND) - Body ground
    		Always
    		Below 1 Ω
    L28-2 (SGND) - Body ground
    		Always
    		Below 1 Ω



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK
