Diagnostic Aids

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.

The HVCID sensor has many different internal configurations in the same external package. Ensure that the correct sensor part number is installed in the correct location.
The HPCM will not clear the vehicle disable condition until both this DTC and the HPCM Impact Detection status have been cleared with a scan tool. Refer to High Voltage System Inspection .
