Hi, I have a problem with electrics on the passenger side of my car. Summary: Rear door - no central locking. Rear door - nothing from window control either from door switch or driver's console. Rear door - no switch illumination. Front door - central locking fine, no switch illumination and window doesn't operate from switch or driver's console (although there is a click when window up actuated from driver's console)
Errors on Forscan are as follows:

No other BCM errors. No errors relating to rear door central locking. Wiring checked - no issues. All grounds are good. No bad connections. 

Any assistance appreciated.

Thanks

Hello Kevin, a very interesting set of problems. Normally I would have headed straight for the BCM but as you say there are no DTC's for the BCM.

I would for the moment forget about the problems with the rear door, I think when you find the problem with the front door it will also solve the rear door issue.

Check very carefully the wiring between the front door and the body A pillar. Look at both the door entry point and the entry point to the vehicle. Check for damaged wires or for signs of water ingress to the multi way connector.

If that seems OK then I'd concentrate your efforts on the Passenger Door Module (PDM) which seems to be reporting a lot of problems. The voltage seems exceptionally low at only 11.00V (I'm assuming your battery to be at least 12.4V or better). This low voltage would suggest high resistance in the wires to the PDM or that the module is if fact faulty.

Hi, yes I am coming to a similar conclusion. I’m almost convinced that the wiring and connectors are ok. Even the one from the front door to the pillar which removes at least an ounce of skin when trying to reach. Connector looks good and I’ve checked earth resistance from all connections on the door wiring. All good. I’ve ordered a 2nd hand PDM which has supposedly been tested. £15 to quickly rule out a faulty module. 
what was confusing me was the B117F code. I wondered if the front window had a Hall effect sensor on it which might be goosed? 
Should be able to swap module out on Wednesday and report back. Thanks for the advice. 

Yes I noticed the "widow down" warning. I assumed that the window was in fact up. My thoughts are that it is just being misreported by the PDM probably due to a faulty unit. The window motor has a small switch contact built inside (very difficult to get at). You could just unlpug the window motor and see what DTC you get.

Do you think it’s possible that the rear door central locking issue is connected? I did read somewhere that the power runs through the lock before going to the control unit? The wiring diagrams in the Haynes manuals are frankly of little use to me. 

Not sure on your vehicle but I think the rear locking goes via the front PDM

So an update. 
fitted a new PDM. All errors cleared except 1. Windows and locks still not working. 
So now there is an error in the PDM and BCMii both saying lost communication with each other. 
BCMii code is U0200 lost communication with Door Control Module B. 
PDM code is U0140 lost communication with BCM. 
So potentially this could indicate wiring issue which killed off the old PDM? 
Voltage still 11.5

IPC reports same lost communication with PDM. 

Forget the 11.5 volts. It hadn’t been started in a while. Back up to 14v now. 

So I may have messed up here. I bought another PDM which was exactly the same serial numbers, dates, you name it. Identical. However, it was from a Jag and I’m now starting to think it will have different programming in it. 
I’m getting different errors now. U0300 and U2100. 
Im still convinced the wiring and grounds are all good and intact. Voltage received at both front and rear modules. 
not sure which pins carry the LINbus on each so haven’t tried continuity between them yet. 
Rear door triggers courtesy lights as does front. 

 I couldn't say for sure but I'd take a guess and say the software will very probably be different.

Maybe you could save the asbuilt details from your old unit and then upload to the replacement ?

Doesn’t seem to be anything in Forscan or ELMconfig which allows that. Not that I can read Russian very well. 
Might have to wait another couple of days for yet another module.

So here is the problem. I took the old module to bits. It’s completely ruined. 

Yup !! that would do it 🤔

 

Have you tried using FORScan and select the PDM then click the AB button (as built). If your laptop is connected to the internet it will be able to get the as built file from Ford.

I would do but under the programming menu, it doesn't list PDM or DDM etc. Odd that I can access all  the MS functions and read DTCs et. All I get is:

PCM,ABS,BCM,RCM and IPC.

Anything listed for DCM ?

Nope - just the ones listed above. It finds the PDM when creating a new profile but programming module only gas those few above listed. I'm wondering if I need a better OBD. I have a VINT BBFly which are supposed to be ok. I do note that Forscan says this adapter is not recommended however.

Ah !!! you have the old programming lead. Not all functions will be available. Use the new 'vLinker FS' with the latest version of FORScan.

Thanks - I just read that this would only perform limited tasks! 😞

But just ordered this: OBDLINK EX FORScan OBD Adapter : Amazon.co.uk: Automotive

 

So should arrive tomorrow. I'll crack this if it kills me - which it is doing slowly!

Only the new vLinker FS cable supports the new 18V programming. You won't need that just now but you will need it for the future. 

If you don't want the vLinker cable at the moment then you should use the ELM327 modified lead from TunnelRat Electronics, which is known to fully work on previous versions of FORScan.

Does that mean the one I ordered won’t work for this task? I can probably cancel it if I’m quick but won’t get another by tomorrow now. 

Does that OBD cable from Amazon switch between the HS Canbus and the MS Canbus? 

Cancel it if you can

It does but not via a switch.
