Driver Knee Bolster Deployment Control (Subfault)

The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a signal cross coupled (short) between circuits. If the RCM detects a short between the circuits of one device and another device, it will store a DTC for each of the signal cross coupled faults in memory. The RCM sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, open circuit or low resistance), then signal cross coupled diagnostics will not be active. Once the normal loop fault is repaired, then the signal cross coupled diagnostics will resume.

Cause:
Faulty Driver Knee Airbag
Driver Knee Airbag harness is open or shorted
Driver Knee Airbag circuit poor electrical connection

Symptoms:
Air Bag Warning Light ON
