SDM commands inflators deployment with loop faults present.
Action Taken When the DTC Sets
- The SDM will only set DTC B0052 or the SDM sets DTC B0053 along with DTC B0052.
- The SDM commands the AIR BAG warning lamp ON via serial data communications.
- The SDM records crash data.
Conditions for Clearing the DTC
After an air bag deployment or 3 separate pretensioner deployments the DTC becomes latched and cannot be cleared.
Diagnostic Aids
| IMPORTANT | 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 SDM.
