For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article.

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. When powered up, the ORC establishes communication with each sensor by sending and receiving acknowledgment messages. The repair of this fault condition centers on confirming wiring, sensor, and module condition.

1. When Monitored: 

   With the ignition on.

2. Set Condition: 

   This DTC will set if the module detects a connection failure at the Left Side Impact Sensor 2 or ORC connectors terminals related to the Left Side Impact Sensor 2. This code may occur in combination with other active DTC's.

Always perform *RESTRAINT SYSTEM PRE-DIAGNOSTIC PROCEDURE
