B0052 00
* The SDM detects a frontal impact of sufficient force to warrant deployment of the frontal modules.
* The SDM detects a side impact of sufficient force to warrant deployment of a side impact module and/or roof rail module.
* The SDM has deployed the seat belt pretensioner for 3 separate deployments.
B0053 00
SDM commands inflators deployment with loop faults present.
B0055 00
* The SDM detects a frontal impact of sufficient force to warrant deployment of the frontal modules.
* The SDM detects a side impact of sufficient force to warrant deployment of a side impact module and/or roof rail module.
Action Taken When the DTC Sets
* The SDM will only set DTC B0052, or DTC B0055, or the SDM sets DTC B0053 along with DTC B0052.
* The SDM commands the AIR BAG warning lamp ON.
* The SDM records crash data.
Conditions for Clearing the DTC
* DTC B0052 can be cleared if the following conditions are met.
- Three consecutive seat belt pretensioner deployment events have not occurred.
- One frontal or side air bag deployment has not occurred.
* DTC B0052 becomes a latched DTC after 3 consecutive pretensioner deployments or 1 frontal or side air bag deployment. The DTC is a
latched DTC and cannot be cleared. Replace the SDM after following the instructions in the diagnostic test.
* DTC B0055 is a latched DTC and cannot be cleared.

Circuit/System Verification
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.
1. Verify DTC B0055 is not set.
瀚慖f DTC B0055 is set, replace SDM.
2. Verify DTC B0052 is not set.
瀚慖f DTC B0052 is set, clear the DTC and operate the vehicle within the conditions for running the DTC. If the DTC resets, replace the
SDM.
3. Verify DTC B0053 is not set.
