Diagnostic Aids

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

A dead, disconnected, or replaced battery can cause this DTC to set and cause the odometer to be blank or incorrect. Driving the vehicle will usually correct the odometer mismatch. Drive the vehicle 1 - 2 miles before attempting a repair or diagnosis.
