  2. TROUBLESHOOTING PRECAUTIONS


    1. If a terminal contact point malfunction or part installation problem occurs, removal and reinstallation of the suspected part may return the system to normal. However, be aware that the normal condition may only be temporary.

    2. Before disconnecting connectors or removing/installing parts, determine the malfunctioning area by checking and writing down the vehicle condition at the time the malfunction occurred (DTC outputs etc.).

    3. Be sure to check for DTCs related to other systems. The pre-collision system may be influenced by malfunctions in other systems.

      • Make sure that the engine switch is off unless otherwise specified in the inspection procedure.

      • After removal/installation, check for DTCs and confirm that a normal system code is output.
