Symptoms - Reduced Engine Power Message: Verification

WARNING: This page is about a different car, the 2011 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

Verify the vehicle is not in an OnStar initiated Stolen Vehicle Slow-Down mode. Look for a Reduced Engine Power message.

If in the Stolen Vehicle Slow-Down mode, perform the OnStar vehicle interface communication module (VCIM) Stolen Vehicle Slow-Down Clear with a scan tool. After performing the clear event procedure, press the Blue OnStar® button to inform the advisor that you need to be transferred to the Stolen Vehicle team to have the vehicle account updated.
