WARNING: This page is about a different car, the 2012 GMC Yukon, 2012 Chevrolet Tahoe, and 2012 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.

The high voltage circuit impact detector sensor has many different internal configurations in the same external package. Ensure that the correct sensor part number is installed with the correct software programmed in the serial data gateway module.
Turn the ignition OFF for 1 minute before using a scan tool to clear the DTC from the serial data gateway module. If the ignition is not OFF for 1 minute, the DTC may not clear.
