Diagnostic Trouble Code Description:
Deployment Commanded
Possible Sensor Faults
SDM - Sensing and Diagnostics Module (Airbag Black Box)
Possible Related Diagnostic Trouble Codes
DTC B0052 or B0053
Circuit / System Description
The inflatable restraint sensing and diagnostic module (SDM) contains a sensing device that converts vehicle velocity changes into an electrical signal. The SDM compares this electrical signal to a value stored in memory. When the generated signal exceeds the stored value, the SDM performs additional signal processing and compares the generated signals to values stored in memory. When 2 of the generated signals exceed the stored values, the SDM will cause current to flow through the deployment loops, deploying the air bags and/or pretensioners causing DTC?B0052 or B0053 to set.
Circuit / System Verification
The seat belt pretensioners may deploy for impacts that are not severe enough to warrant frontal or side air bag deployment. The SDM is capable of sustaining 3 pretensioner deployment events, or one frontal or side deployment event. After the maximum number of deployments has occurred, DTC?B0052 sets and becomes a latched code, which cannot be cleared.
When DTC?B0053 is accompanied by additional DTCs, other than B0052, repair the malfunction causing the other DTCs before replacing the SDM.
Ignition OFF, verify no signs of inflator module or pretensioner deployment exist.
If any signs of deployment exist, refer to Repairs and Inspections Required After a Collision.
Verify DTC?B0053 is not set.
If DTC?B0053 is set along with additional DTCs, other than B0052, repair the malfunction causing the DTCs before replacing the SDM.
Verify DTC?B0052 is not set.
If the DTC resets, replace the SDM.
