Causes the technical documents say how to deal with (6)
Air bag lamp on with DTC B0092 (passenger presence system sensor harness)
1 matching record
The air bag lamp is on, the passenger air bag indicator always reads OFF, and DTC B0092 is set.
How to tell
- B0092
- Air bag light
What to do
- The correction is to repair the passenger presence system (PPS) sensor harness.
Coil Harness: design or manufacturing
1 matching record
AIR BAG indicator on with side impact module DTCs (connector CPA replacement)
No matching record (stated by the technical documents)
The AIR BAG indicator is illuminated and side impact module DTCs B0028, B0029, B0040 and B0041 are set.
How to tell
What to do
- The correction is to replace the wiring retainer CPA of the passenger/driver seat side inflatable restraint module at the side impact module connector in the seat.
Air bag sensing diagnostic module (SDM) anomaly - recall 02V-178
No matching record (stated by the technical documents)
Some vehicles have an SDM with an anomaly that could keep the driver and passenger air bags from deploying in certain frontal crashes.
How to tell
- Air bag light
What to do
- Dealers recalibrate the SDM.
SIR lamp on and inside mirror temperature/compass display inoperative (open air bag fuse, circuit 1139 shorted to ground)
No matching record (stated by the technical documents)
Owners of a 2003-06 full-size utility or 2003-07 classic pickup may comment of a SIR MIL, and the temperature/compass display on the inside rearview mirror, if equipped, is inoperative.
The concern may be caused by an open 15 amp air bag fuse.
How to tell
- Air bag light
What to do
- Circuit 1139 (yellow) may be shorted to ground at the left I/P junction block mounting bracket.
- To correct the concern, repair the wiring as necessary and insulate the harness and the mounting bracket with foam tape to prevent a reoccurrence.
Air bag (SIR) lamp on with DTC B1001 after BCM or SDM replacement
No matching record (stated by the technical documents)
The SIR lamp stays on steady after an SDM or BCM has been replaced, with DTC B1001 current in the SDM.
The SDM compares the restraints ID stored in the SDM to the restraints ID stored in the BCM.
How to tell
- B1001
- Air bag light
What to do
- A replaced SDM or BCM must learn the restraints ID.
- On some vehicles a calibration may need to be selected after choosing "Vehicle Theft Deterrent - Learn"; select the one labeled "Vehicle Theft Deterrent for Passlock sensor".
- A replaced SDM or BCM must learn the restraints ID, which requires performing a 10 minute V.T.D. "Vehicle Theft Deterrent - Learn" with the Tech 2.
