I have problem with my FFE 2014. When I operate accelerator pedal everything is ok, but when I stop operating car goes into service mode and turn off. I need to restart it by pressing start button.
Errors which I read from Forscan:
P0AFB Code - Battery System Voltage High
P0C07 Code - Drive Motor 'A' Phase U-V-W Circuit High
P0C05 Code - Drive Motor 'A' Phase U-V-W Circuit/Open
Sometimes I had errors with stucking "plus"contactor
I replaced TCM for used one, but it didnt solve my problem. After few test rides I have new problem - car doesnt start and I have error:
P0AF8 Code - Hybrid Battery System Voltage (too low)
Do you have any ideas what should I check now?
Where is + and - contactors? Both are at upper battery pack?
