Ford Super Duty (1999-2016) :: 2003 - 4wd Control Module Test
Jul 6, 2017
I have been trying to hunt down the issue with my 4wd. I have thus far done the following:
- Check and clean all fuses under dash
- Checked the underhood relays
- Check for proper operation at switch
- Opened relays under how and manually switch them, transfer case motor and lights on dash work as they should.
So my though is that I have power going everywhere. Something is not sending the signal to the relays. I would narrow this down to the 4wd control module behind the glove box. Is there any way to test this for sure? I'm about ready to just buy on and slap it in. Spending way too much time on this issue.

I have a 2002 F350 7.3 Powerstroke with approximately 200,000 miles. Recently I have been having an issue with what I am told is my airbag control module heating up to the point it is too warm to touch when I am pulling a heavier load. It is located just under the dash on the center hump. I removed the black plastic cover revealing the module itself in order to determine that indeed is where the heat and smell of hot electrical equipment is originating from. It gets too hot to touch when pulling a heavy load and making the motor work...once I lighten up on it or am not pulling it immediately cools back down. If it is an option I would just disconnect it but I havent yet for fear of creating more of a problem.

I have a 2002 F-250 Super Duty 4X4 triton V-10. Where the security control module is located? my keyless remote system does not work even after programming a new remote. The Ford dealership charged me an hour labor to diagnose the problem and they said it's the security control module which I just ordered.

So I had an issue with the trans temp sender leaking out of the test port where it's installed. My first clue was a smell of ATF, then a high trans temp, and finally many, many spots on the driveway. Anyway, I discovered that either I lost the o-ring for the sender or it didn't come with one. Regardless, I got an o-ring and its sealed for the most part. There is still a drop or two under the truck after it has been running. How can I fully get rid of this issue? Would some RTV thread sealer do the trick?

Just bought the 03 listed in my signature line, and I just found out that the cruise control isn't working, so started trying to troubleshoot anything obvious.
When I switch it on, I get no cluster light that the manual shows to be to the right of the brake light. When I turn the key to run, it never lights up, so am guessing the bulb is bad.
Can't see how a bad bulb would keep the system from activating, so am thinking I have bigger issues. I pulled the fuse panel, but the manual does not have a listing for speed control. Which fuse it is combined into?
Also need the skinny on how to change the bulb. Can I reach my hand behind there? does the cluster have to come out?
Last question. What is the most likely culprit for non functioning cruise? A module? Perhaps the switch in the steering wheel?

I have a 2003 f-250 5.4l and the cruise control quit. If you press the on and coast it will honk the horn so I am thinking switches on the steering wheel or the clockspring. I need to test those. Everything else works fine....

I have a 2003 F250 Super Duty 5.4 crew cab. Cruise light comes on when engaged but does not work. I did some research on why its not working checked wiring at the throttle body it seemed ok, Fuse is ok. Also did the self test and everything passed with just one flash but cruise still does not work. I read about many problems with the brake pressure switch but would it pass the self test if that pressure switch was bad? Also what should a switch cost. Local dealer wanted $125.00 for a new one and I have read where they cost around $15.00 - $20.00.

Problems with the Parking Assist/Reverse Sensing System. I have found the troubleshooting that everyone has done very useful. I have a 2007 F350 Lariat Crew Cab with problems with the Park Assist. Whenever I put it in reverse the system shuts off( Off Light illuminates). I have checked the wiring harness and all connections, Parking switch, and Reverse Sensors. I have done everything except check the Parking Assist Module. My maintenance DVD tells me that it is located behind the glove box. I cannot find it in there anywhere. Where it is located. The trucks manufacture date is June 2006....

2009 F250 Super Duty 4X4 auto lock hubs not working. Indicator lights on dash come on but will only go into 4 wheel drive when hubs are locked manually. Vacuum is present at lower of the two vacuum lines when engine is running. I attach the lower line to the module, rotate switch to 4X4 high or low and module doesn't allow vacuum to reach upper nipple. Which fuse operates this module?

2010 F250 Lariat, cab and a half, PSD. 5600 miles.
Sunday I started the pickup and received "trailer brake module fault" in the message center. I wasn't pulling so wasn't too concerned - hit the reset and continued on.
Sunday night I started the pickup again and received the same message followed by "check brake system". I also lost illuminated gear selection, the traction control active symbol was displayed and the traction control "off" (PB) was illuminated. After several attempts it reset, everything returned to normal and I was able to get home without incident.
Monday morning it wouldn't start. It indicated "trailer brake module fault", "check brake system", traction control active and off, no gear indication, the odometer indicated "-------" and it did not react to the key in the start position.
Tuesday morning I attempted to start and it was the same as the previous attempt. I noticed that the theft prevention appeared active (flashing) so I removed the key, locked the doors, unlocked the doors, tried again - no joy.
I kept trying while holding my mouth in different positions and finally by the grace of God it fired. I delivered it to the dealer.
The dealer called yesterday afternoon and reported that everything is a result of a bad trailer brake module. The new one is to arrive today, they will install and everything will be peachy.
I asked if they could just unplug it and reprogram the truck to believe it never had one - the service writer said it can't be done, different piece parts on trucks with or without trailer brakes.
I really have no choice but to push the "I believe" button and carry on but I am slightly concerned. The fact that the trailer brake module can cause catastrophic failure doesn't seem too cool, I don't have a real warm and fuzzy feeling associated with venturing far from pavement, reliable communication or alternative transportation.
In the meantime I suggest that no one take "trailer brake module failure" lightly.

How to fix SES P0670?? I understand there's a whole procedure on checking fault.
P0670:GPCM Glow plug control module control line failure. Open/grounded circuit, open/shorted GPCM, failed PCM
But how did you resolve problem? replaced GPCM, found open circuit, short --if so where?-- or replaced with updated harness.
(4C3Z-12B568-AA connector upgrade kit as in picture)???

02 E450 Super Duty V10, C class a motorhome, 29000 miles. Cruise stopped working a month or so back. I searched this forum and managed to fix it with the info provided. It turned out to be the pressure switch on the master cylinder, the recall had been done. I replaced the pressure switch and the harness with an aftermarket one from the local auto parts store. It worked well for about 200 miles, it knocked off again on our road trip last week. It was working on the road and we stopped for breakfast and it didn't come on again, no light in the dash or anything.
When I ran the internal diagnostics on the first repair all the lights would flash when the buttons were pressed and the servo would cycle through at the end of the test as it should, based on the diagnostic instructions. This time when I run the diagnostic test the light will flash when I first turn the switch on (holding the off button down) and when I push the on the button but will not flash when I press the other 3 buttons.
I have not been able to find a wiring diagram for this particular truck, I've found 6 or so but none of them match my fuse boxes under the hood and dash.
I have no trouble lights on in the dash CEL or ABS. I'm at a loss what direction to take from here.

OK, what does a glow plug control module do? The short bus I got has one on it. It looks like it fits right into the circuit without much, if any, modification. I got one with my short bus and am curious if it would be something worth adding to my pickup. So...what does it do and could I/should I install it?

2014 f250 6.2........today on my way home from work I noticed my traction control symbol was on. It didn't say off under it like it does when you turn it off. About five miles down the road it was gone. What might of caused this?
Another thing I've been wondering is whats up with the carpeted inner fender wells. How long has ford been doing that and how well do they hold up?

I've got a '08 F250 XLT that the cruise control has become intermittent. It works most of the time but at times it will "go out to lunch" and not do anything. I've taken the controls from the wheel and didn't see any gummed up coke spills or anything there. It may not be anything but twice when it failed while on a trip I pulled over and shut the truck down. Started it up and the cruise would go back to working. Once I did this and it went back to working only to shut off in about 2 seconds but I was able to engage it again and it kept working. When it stops working there is no green indicator on the dash either.
