Customer’s concern: Passenger power window intermittent, A/C inoperative 

Upon initial inspection, both concerns were present. I also noticed the airbag light was illuminated, but the customer was only worried about the A/C and power windows. 

I started diagnostics by performing a vehicle DTC scan. However, after DTCs were retrieved, the A/C and power windows started working.

The following DTCs were present:

All (CMDTCs)

  • Pass - (ABS)
  • Pass - (ACM)
  • Pass - (APIM)
  • Pass - (DDM)
  • Pass - (GPSM)
  • Pass - (GWM)
  • Pass - (OCSM)
  • Pass - (PCM)
  • Pass - (PSCM)
  • Pass - (RTM)
  • Pass - (SCCM)

U0200:87-0A- (BCM)- Lost Communication With Door Control Module B - Missing Message -Current (DTC), Fault is currently present.

U0256:87-0A- (BCM)- Lost Communication With Front Controls Interface Module - Missing Message - Current (DTC), Fault is currently present.

U0256:00-08- (FCDIM) - Lost Communication With Front Controls Interface Module - No Additional Failure Type Information for this (DTC) - Not Current (DTC), Fault previously detected, not currently present.

U0140:00-08- (FCIM)- Lost Communication With Body Control Module - No Additional Failure Type Information for this (DTC) - Not Current (DTC),Fault previously detected, not currently present.

U0155:00-08- (FCIM)- Lost Communication With Instrument Panel Cluster Control Module - No Additional Failure Type Information for this (DTC) - Not Current (DTC),Fault previously detected, not currently present.

U0557:81-08- (IPC)- Invalid Data Received From Front Controls Interface Module - Invalid Serial Data Received - Not Current (DTC),Fault previously detected, not currently present.

U0557:82-0A- (IPC)- Invalid Data Received From Front Controls Interface Module - Alive/Sequence Counter Incorrect/Not Updated - Current (DTC),Fault is currently present.

U0140:00-08- (PDM)- Lost Communication With Body Control Module - No Additional Failure Type Information for this (DTC) - Not Current (DTC),Fault previously detected, not currently present.

B0070:13-AF- (RCM)- Driver Seatbelt Pretensioner Deployment Control - Circuit Open - Current (DTC) - Warning Lamp On,Fault is currently present, warning lamp on ((MIL), Wrench, Message Center, etc.).

B007E:13-AF- (RCM)- Driver Seatbelt Pretensioner C Deployment Control - Circuit Open - Current (DTC) - Warning Lamp On,Fault is currently present, warning lamp on ((MIL), Wrench, Message Center, etc.).

B1193:00-AF- (RCM)- Crash Event Storage Full and Locked - No Additional Failure Type Information for this (DTC) - Current (DTC) - Warning Lamp On, Fault is currently present, warning lamp on ((MIL), Wrench, Message Center, etc.).

B1408:13-AF- (RCM)- Passenger Side Curtain Deployment Control 1 - Circuit Open - Current (DTC) - Warning Lamp On, Fault is currently present, warning lamp on ((MIL), Wrench, Message Center, etc.).

U3000:49-E8- (RCM)- Control Module - Internal Electronic Failure - Indeterminate - Warning Lamp On, Fault previously detected but monitor has not completed to determine state, with warning lamp on ((MIL), Wrench, Message Center, etc.).

Since the fault preventing AC/Power window operation cleared up on its own, I now had to gather as much information as I could just from the DTCs. Based on the DTCs, it appeared a network fault was causing the issue. There were several DTCs indicating the Front Controls Interface Module (FCIM) and Passenger Door Module (PDM – AKA: Door Control Module B) was not online. I now needed to find something in common with both modules. 

The wiring diagram shows the PDM and FCIM connected to Splice Block 36. According to the Service Information, Splice Block 36 is in the passenger kick panel. 

DTCs were cleared and the only DTCs that returned were for the Airbag system. I was able to reduplicate the customer’s concern by wiggling the wiring harness around the arrow. The communication DTCs returned as well. 

The Splice Block was cut out and the connections were hard wired which resulted in resolving the concern.

My initial plan was to test the MS-CAN circuits. Since this vehicle uses a Gateway Module, you can’t simply access the MS-CAN circuits at the DLC. You must access those circuits at the Gateway Module connector or at another module. Fortunately, I was able to diagnose this concern by isolating the fault based off DTCs.

Rotunda now makes a breakout box for the Gateway Module connector. I don’t have one of these yet, but plan on getting one soon. 

Here's entire IDS Session Log for reference.

Ford IDS performs quite a bit of job logging and allows you to go back and see important items such as time, tests performed, faults, and a whole lot more. I'm considering writing up some tutorials with best practices around IDS if there's enough interest. Please let me know if this is something that interests you.

The two wiring diagrams referenced were accessed through Ford's factory information system.

Thanks for reading.

Nice right up !! This afternoon I had a problem on a GMC Acadia which went down about the same as your Ford problem.

Excellent as always Robby. As for the IDS best practices I am sure if you write it will be worth the read. If anyone is interested in the Gateway module breakout box Rotunda has a video with more info youtube​.​com/watch?v=PH8sga…​.​be

Great write-up Robby, thanks for breaking down he logical steps taken to resolve the issue. I have a question about the splice block, why was there a connection issue? Was there corrosion? Second question is about IDS, how do you prevent the application from eleiminating your logs/recordings? I wanted to reference reference some log files recently and when I looked, I found that the stuff I

There was corrosion in the Splice Block. This vehicle was a flood car that, according to customer, came out of North Carolina. However, Ford has used a couple of different Splice Blocks over the years, and they all have given problems. It's not just the Splice Blocks though. The Splice Blocks use very small terminals that develop bad connections. Many wiring harness connectors being used now

Thanks Robby, ”Flood Vehicle” explains it and what’s sad is that this vehicle will likely continue to experience problems well into the future IMO. On the IDS files, thanks for the insight. i know that we’ve chatted about this in the past, I think it would be great to see an article or two covering IDS which ultimately would be providing valuable insight.
