Hi, has anyone had issues with door locks not working on the X250. I've got a new one here, doors unlock from the dash switch, but won't lock. The cargo doors both lock from the switch on the RH door panel, but none lock from the centre dash switch panel, nor will they lock from the driver's door, but they will unlock from driver's door. I've checked the diagrams, and accessed the system with a Fiat Examiner scanner. I can activate door lock/ unlock from scanner (they all work), the scanner also registers the door lock switches activating (ie; turning the key in the lock), in both lock/unlock modes. It gives no fault codes, but the rear door open light is up in the instrument panel. I have tested the rear door wiring, it is fine, but I suspect the fault lies with the slider. If it shows at the BCM as being open, it probably won't allow the DLM to lock the doors.
My problem here is that the vehicle has been completely kitted out, and I can't access the o/e looms at present, due to the interior lining. I'm hoping someone may have a standard RHD hi top van, and be able to tell me where the rear and side door looms lie, and what position the connector plugs are in relative to B and C pillars, etc. The fact that they all can be operated from the scanner tells me the door solenoid circuits are all ok, but the fault most likely lies in the door open circuit on the LH slider.
Cheers.
 
Slide the load door open and you will see contacts about a foot up from the floor.
Black plastic panel pulls off.
I found my door open light comes up if the door is mis-aligned. Found this after I had a new load door fitted after doing battle with barrier in a petrol station.
