Diagnostic Aids

If ignition voltage is out of normal range, (9-16 volts), AIR BAG warning light will come on with no Diagnostic Trouble Codes (DTC's) set. Loss of serial data communication between SDM and Instrument Panel Cluster (IPC) will also cause AIR BAG warning light to come on.

NOTE: For circuit number and wire color identification, see WIRING DIAGRAMS .
