I disconnected connector X2377 from the DDE module, and checked all the pins of the connector against ground, but I didn’t find any shortcut. I thought that those sensors are connected first to the fuse box and then to the DDE, but the X2377 connects directly to the DDE module. I was thinking to find at least one sensor, to check the cable, just to be sure that this is the right connector, but I didn’t manage to find any one, I have to dismantle half of the engine bay to reach them.
Any ideas?
