INSPECTION PROCEDURE

PROCEDURE


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


    1. A0162CFE02

      Disconnect the J29 connector from the steering lock actuator assembly.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J29-1 (GND) - Body ground Always Below 1 Ω
      J29-2 (SGND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BATTERY)


    1. A0162CFE04

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      J29-7 (B) - J29-1 (GND) Always 10 to 14 V
      J29-7 (B) - J29-2 (SGND) Always 10 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BATTERY)
