Diagnostic Trouble Code Description:
Driver Frontal Deployment Loop Stage 1
Possible Sensor Faults
SDM - Sensing and Diagnostics Module (Airbag Black Box)
Possible Related Diagnostic Trouble Codes
DTC B0012 or B0013
Circuit / System Description
During a frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the steering wheel air bag. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. There are 2?shorting bars used within the steering wheel air bag coil connector which will short together both steering wheel air bag stage?1 high circuit and steering wheel air bag stage?1 low circuit and both steering wheel air bag stage?2 high circuit and steering wheel air bag stage?2 low circuit when the connector is disconnected. This will help to prevent unwanted deployment of the steering wheel air bag during servicing.
Circuit / System Description
A worn steering wheel air bag coil can cause a repeated history DTC to set with symptom byte 04 or 0D. To verify this condition, turn the steering wheel 360 degrees in one direction then back 360 degrees in the other direction, multiple times, while viewing the scan tool Deployment Loop Resistance 1 and 2 parameters.
An incorrectly installed CPA or incorrectly seated connector can cause a shorting bar to short both control circuits together. Check the connectors and CPAs if a DTC with symptom byte 02 or 0E is set, to ensure the shorting bars are not causing the circuits to be shorted together. Shorting bars are used in the locations listed below:
Steering wheel air bag assembly
Steering wheel air bag coil assembly
Inline connectors - on the steering wheel air bag side of the harness connector
Harness side of the SDM connector
Terminal fretting, an incorrectly installed CPA, or incorrectly seated connector can cause an open/high resistance condition. Check the circuit terminals for fretting, an incorrectly installed CPA, or incorrectly seated connector if a DTC with symptom byte 04 or 0D is set.
If the steering wheel air bag has inflated under unexpected conditions and/or DTC with symptom byte 01 is set, check both control circuits for a short to voltage.
