Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at terminals ª3º and ª4º of the driver
pretensioner assembly 2±pin connector at the base of the
driver seat. SDM terminals ª21º and ª22º or a poor wire to
terminal connection in IB13±BLU/RED orIB14±BLU/YEL. The test for this diagnostic trouble code
is only run while the ªAIR BAGº warning lamp is
performing the bulb check. When a scan tool ªClear
Codesº command is issued and the malfunction is still
present, the DTC will not reappear until the next ignition
cycle.
