Conditions for Setting the DTC (SDM)

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The 4-digit primary data key stored in the SDM does not match the 4 digits stored in the BCM.
The VIN stored in the BCM is not in the acceptable range of VINs allowed by the SDM calibration.
