My DS5 Hybrid 4 2012 no start after after several months of parking.
The small battery has been charged. but the control units of the “large” battery do not communicate. In other blocks there are errors in communication with these blocks: U1288 Can Hybride, U1187 Can Hybride, U0293 Can.
Unfortunately, I can’t find a wiring diagram for the battery control unit and the hybrid drive control unit. Perhaps they are not receiving power (are the wires damaged?). Someone knows how to check the voltage on the rear battery?
