Diagnostic Aids
WARNING: This page is about a different car, the 2011 GMC Yukon, 2011 Chevrolet Tahoe, and 2011 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.
Conditions such as loss of battery energy control module power or ground or removal of the high voltage manual disconnect while the vehicle was driving could create a voltage surge that may set DTCs P1AEE and P1AEF. History DTCs P1AEE and P1AEF may indicate that the high voltage contactor relays opened while large current flow was present.
