INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the side monitor system may be needed Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - OUTER REAR VIEW MIRROR ASSEMBLY AND BODY GROUND)


    1. Disconnect the F75 and F76 parking assist ECU connectors.

    2. Disconnect the I35*1 or I32*2 outer rear view mirror assembly (for Driver Side) connector.


      • *1: for LHD

      • *2: for RHD

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