Vehicle Information
Condition
Airbag Warning Lamp - Front Side Airbag Pressure Sensor Interruption/ Short to B+
Note:
The condition as described does not affect airbag operation.
Airbag Warning Lamp Illuminated in Instrument Cluster and one or more of the following DTCs are stored in the airbag control module:
Technical Background
The Airbag Lamp in the Instrument Cluster may illuminate due to an unsecured electrical connection at the Driver (G179) or Passenger (G180) Airbag Pressure Sensor located in the front door. This condition could also be caused by an unsecured electrical connection at the inline connector between the Airbag Pressure Sensor and the Airbag Module (T28 or T28A) located in the A-Pillar. It is critical to ensure there are no connector or terminal concerns before suspecting the G179 or G180 Airbag Pressure Sensors.
If the DTC B101715 and/or B103615 are present, check for any additional DTCs in the Airbag Module. If there are additional DTCs present such as faults for Outside Mirror Turn Signal Electrical Malfunction, Front Door Warning lamp Electrical Malfunction, Door Control Module, Bass Speaker, or Lock Unit for Central Locking, perform a visual inspection of the T28 and/or T28A connectors in the A-Pillar area.

Service
Procedure:
^ Verify airbag indicator lamp in instrument cluster is ON.
^ Using GFF, scan vehicle for DTCs.
^ Verify DTC B101715 OR DTC B103615 is stored in airbag module.
^ Understand if any previous repair or customer action would have resulted in the door harness being disconnected.
No Door Module Faults:
Tip:
If Vehicle only has pressure Sensor Faults B101715 OR B103615 showing in GFF:
^ Disconnect battery negative cable.
^ Remove door panel and ensure secondary lock is fully seated on the pressure sensor.
^ Verify pressure Sensor (5K0.959.354) is properly installed in the front door.
^ Inspect wiring from pressure Sensor (5K0.959.354) to T28/T28A A-Pillar Door Connector.
^ Verify T28/T28A Door Connector Pin 12 and 13 are fully inserted and there are not connection issues.
^ Verify T28/T28A Door Connector does not have moisture contamination, and that the connector is fully inserted and locked into the A Pillar mating connector. The connector locking bar needs to be fully seated and no damage is present.
^ Reconnect battery negative cable.
^ Clear fault memory and recheck for code.
^ If fault clears, no connector or wiring damage was found, and the airbag indicator in the instrument cluster does not illuminate, no repairs necessary.
^ If the faults do not clear, all connections are secure, and no wiring damage is present further diagnosis is needed. This technical bulletin does not apply.
^ Clearly document all checks and findings in the warranty system. Open VTA for any loose/damaged connectors or wiring.
(With Door Module Faults):
Tip:
If Vehicle has pressure Sensor Faults B101715 OR B103615 AND Door Faults in the Electronic Control Module:
