I'm getting 4 error code in my FCIM module.
U0155:00-08 Loss Communication with Instrument Panel cluster Control Module
U0253:00-08 Loss Communication with Accessory Protocol interface Module
U0401:82-08 Invalid Data Received from ECM/PCM (Addition Fault Symptom: Alive/Sequence Counter Incorrect/Not Updated)
U0452:82-08 Invalid Data Received from Restraints Control Module (Additional Fault Symptom: Alive/Sequence Counter Incorrect/Not Updated)

Anyone know what could be causing this? I resetted everything 3 days ago and checked today and those 4 errors came back.

 

Still under warranty?

 

Have you done any computer mods?

 

whats your vin i'll run em and see if something pops up

 

Vehicle is brand new 2 weeks old. No computer mods, jsdecorte I pm'd you my vin. I'm going to bring it to the dealer but what I was looking for was information on troubleshooting these error codes so I understand the issue so the dealer doesn't try to give me some BS response. This error doesn't seem to affect any operation of the accessories except my rear outer bumper sensors often frig up and give a constant alarm tone, not sure if related or not.

 

I would say one of your computers is having a hard time talking on the CanBus. One of two reasons a ground messing up or a bad computer. Either way if it is under warranty let the dealer chase it. They have ways of testing the Bus that should lead them to the problem. I have a Jeep Wrangler that was tossing codes for the first two years I had it. They figured it out after awhile. I hope the Ford Techs are better then the Jeep Techs.

If you have a code reader, just read them do not clear them. The Tech will need to know the count of each code.

 

The truck is only 2 weeks old, I resetted the codes last week when I received my ODB2 MX adapter. I was planning on making some minor changes with forscan but I hadn't yet. At first I thought maybe the codes came up when the Ford techs installed my levelling kit so I cleared them. The codes came back, I didn't reset them since.

I've been reading on CAN and also on the protocol in efforts to be able to troubleshoot these type of errors after warranty. I plan on getting a cheap scope later on because I want to be able to work on my vehicle myself once out of warranty.

Are there service manuals (hopefully free) for my vehicle available anywhere?

What does the FCIM Front Control Interface Module control?

 

No free Service Manual yet, these are still to new. Before I would do anything with the Forscan tool, I would wait until the CEL is taken care of.

As for what that computer controls, I'm not sure. I teach electronics and computer networking for a living and we use the CanBus protocol to talk between some of our systems.

 

These error codes do not activate the CEL thats why I wanted to make sure I knew as much as possible about the issue in case the dealer says something stupid like its normal , or they see this all the time.

 

Is this the same shop manual that the techs use?
