    • FOUND: code p0aa4 stored in the battery energy control module. Code indicates that the negative contactor circuit was stuck closed. Cleared the code and was able to start and move the vehicle. There is a possible failure of the negative contactor relay. We'll need to perform further testing may require accessing the high voltage battery and disassembling the battery case to access the high voltage battery junction box.
