Circuit/System Verification

WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
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.
    • If DTC B0055 is set, replace SDM.
  2. Verify DTC B0052 is not set.
    • If 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.
    • If DTC is set along with additional DTCs, repair the malfunction causing the DTCs before replacing the SDM.
