Left Front Impact Sensor Internal 1: Notes

For complete wiring diagrams, refer to SYSTEM WIRING DIAGRAMS article.

  1. When Monitored: 

    With the ignition on.

  2. Set Condition: 

    The Occupant Restraint Controller (ORC) supplies power to and communicates continuously with each impact sensor via each sensor's signal circuit. The power supply also enables each sensor's self-diagnostic capabilities. If an impact sensor detects an internal fault, it sends the applicable Impact Sensor Internal 1 message to the ORC. The ORC will set this DTC if it receives the Left Front Impact Sensor internal 1 message.
