Diagnostic Aids
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.
Because the engine and drive motor 1 are mechanically connected through a planetary gear set, an engine condition that requires drive motor 1 to consume excessive current while trying to rotate the engine may cause this DTC to set such as:
- Extreme acceleration from stop may cause this DTC to be set in history.
- Extreme braking during regeneration may cause this DTC to be set in history.
- Seized or binding engine
- Seized or binding accessory drive belt
