INSPECTION PROCEDURE

Tech Tips


  • All doors can be locked/unlocked simultaneously using the following items:


    1. Door lock knob linked with driver side door lock

    2. Door key cylinder linked with driver side door lock (key operation)


  • If all the doors cannot be locked/unlocked simultaneously, proceed to the next step according to the malfunctioning part shown in the table below.
