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.
Before disconnecting connectors or removing/installing parts, determine the malfunctioning area by checking and writing down the vehicle condition at the time of the malfunction (DTC outputs etc.).
Be sure to check for DTCs related to other systems. The pre-crash system may be influenced by malfunctions in other systems.
