Ford 6.7L Power Stroke Diesel :: Fuse For Transmission Control Module Started Blowing
Jul 6, 2017
I have a fleet of F250s and 350s through my business. I have recently been having problems with a f250 2015 6.7. It has approximately 110k miles and a new transmission was put it about 12,000 miles ago. Since then we haven't had a problem until now. Recently (2 days ago) it started blowing a fuse, #46 (transmission control moduler) and lighting the entire dashboard up like a Xmas tree.
Check engine light, maintenance required, hill descent, etc. However it is completely random when it does this. It has happened a total of 11 times in 2 days. 6 times in a row yesterday then didn't do it until late this evening 5 times in a row. It will get parked, turn it off, try turning it back on and the fuse is blown, replace it same thing... then will eventually start.

I have an 03 6.0 F250. My truck started blowing fuse #45 and it would kill my gauges (fuel, oil, mph, rpm, temp, trans temp, and odometer) and I was just replacing the fuse and putting off the repair.
However, the most recent time my gauges blew, the fuse did not, and I put in a 20 amp fuse, in hopes that it would not blow so quickly, bad idea. So naturally, I ordered a new shift lever, in hopes that it would fix the gauges and I wouldn't have to deal with it anymore, but I think it was too late and something else needs to be replaced. What I could possibly have blown by having a larger fuse in there?

Need to diagnose this before I start ripping wires:
Truck started blowing the # 8 fuse under the hood tonight (15 amp #8 - trailer tow electronic brake illumination, park lamps, trailer tow park lamp relay coil fuse) which also controls the dash board lights (can't see gauges at night) and the tail light lights (brakes lights work) are out too. Figure I have a short somewhere.

I purchased 2011 F250 King Ranch Edition about 3 months ago. I'm loving the truck and not had any issues until 3 weeks ago. I locked the truck as usual using the key Fob, and upon returning to the truck, I noticed the doors weren't locked. After some brief trouble shooting, I discovered the the fuse was blown that according to the manual controls just the power door locks. I thought it was strange that a new truck would be popping a fuse so I replaced it...a couple of days later it blew again. This time I was locking the truck with the door key pad. I took it to the dealership and they checked it over and said they replaced the fuse and cycled it numerous times but could not reproduce the problem. The told me that they even put a call in to the Ford engineers and they said check the key pad for water intrusion. The dealership told me they disassembled the key pad and found nothing wrong....lock and unlocked the door some more and the fuse would not blow. I picked the truck up four days ago and the fuse blew again last night. Everything else works...alarm sets and goes off if any of the doors are opened. The only thing that I can find that doesn't work when the fuse is blown is the remote start.

I completed the high idle mod on my '05 Excursion 6.0 a few months ago. The 12V source is the blue/white wire that up/right of the ODBII connector outlined in the high-idle mod how-to.
For some reason, every couple of weeks, the 10-amp mini fuse at #29 will blow. It will work well for several weeks - then randomly pop the fuse about once a month.
Not sure if maybe I should swap out the switch I'm using to toggle the high idle, or maybe if an increase in the fuse amperage is required...or something else?

My 2006 f-250 just started blowing the #22 fuse when i go over a bump! Where the wire harness is for this. I've checked all the harnesses I could locate that looked like they could be rubbing on something.

I have a 2006 f350 king ranch 4x4, I recently used 4 wheel drive and could not disengage it, it would go into 4 low but would not go back to 4 high or 2 wheel drive, I unplugged the actuator harness and applied 12 volts to the terminals and it disengaged, I reversed the power and it engages, the actuator seems to work properly, I then replaced the two relays located by themselves on the front fender driver side, when I try to install the 30 amp female fuse located in the outside fuse panel rear driver side, fuse #3 for 4x4 shift on the fly it blows immediately, it makes no difference if the harness is plugged into the actuator or not, if I remove the two relays then I can install the 30 amp fuse, but as soon as I try to install the relays it blows the fuse again..

I have a 2012 6.7 with a Spartan tuner. Threw this code a few months ago. Reset everything, trucks runs great, no issues. Never had this code come up again. I've looked it up and it says, "Internal Control Module Torque Performance". I'm just not sure what this means.

So; I bought my 07 f350 6.0 the other day. I have a light on that sends a code for glow plug control module, but the truck starts fine, the same in cold temperatures as warm, so far nothing below 32 degrees though. I dont have the code # at the moment, but will update when i get the scanner back. Why this module is throwing a red flag?

Had just got done filling up with diesel, drove 1/4 mile and truck just died. Tried to start it and nothing. No power to edge tuner either. Fuse #22 20a under steering column blown (engine control). Replaced and keeps blowing. not sure what is causing it. Just another wrench to throw in my wedding week!

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)???

I have an 04 F350 automatic blowing fluid out under load only. Had it serviced the first time it happened two weeks ago. They found no issues and replaced the fluid and filters. Drove truck about fifty miles, no load, no problems. Took her out this morning in tow/haul mode with load and made it about 20 minutes before I noticed it warming up. Pulled over and it is blowing fluid out the right side of the pan.

Out of nowhere my fuse #30 has started blowing - thats the one that supplies the DC outlet points, or cigarette lighter plugs. And no, there are no pennies stuck in the outlets!
I've removed and unplugged all 4 outlet points from the loom, thats the one on the dash, inside the center console, behind the center console and lastly the one in the boot. Still a total dead short.
I've disconnected the 220v AC inverter thats behind the center console, and still measure a dead short.
What else does this fuse/line supply? The only things not working are my lighter plugs, everything else seems fine. Any wiring diagram perhaps - I'm sure there hasn't been much of a change in interior wiring over the years.

Can I change these out to hydraulic hoses with clamps that are rated for the fluid. Mine are rusted and starting to leak.

Recently picked up a 2004 Ex 6.0L. Drove great for a bit, then it started shift badly, then finally the Tow/Haul light came on. The original codes were P0976 and P0755.
P0755 being shift solenoid B, and the P0976 being SSB Control Circuit low. I replaced Solenoid B and that code went away.
P0976 stayed with no change in how the truck drives. Replaced the internal harness today, and again no change.
At this point I'm at a loss. I'm wondering if it's something between the PCM and the transmission?

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?

I had a problem with this issue a few months ago, was 45 minutes away from home, blew the fuse to the starter. Switched another one in, blew it too. Had it towed to a shop, they did some diagnostics, felt like it was a short in the starter, replaced it and all has been well (as far as that particular issue) until this morning. Got in it, turned the key it cranked for less than a second and stopped. I pull the fuse, sure enough, blown. Swap it with another, it blows.
I know I have a bare wire in the column, the OD light wire is chaffed, I fixed it before but it must be worn again because I can get it to light up depending on positioning of the shifter lever and as I recall, every time the fuse blows the steering wheel is cranked to the left.

Upon trying to start my 2003 f250, it keeps blowing the 15A "Transmission Range Sensor then to Starter Relay Coil" fuse. Initially the truck would still start if i did not use the aftermarket Viper keyless start. however, now it doesn't start at all and keeps blowing fuses. I contacted the guy that installed the alarm thinking it might be something on his end. He walked me through reconnecting the factory starter wires which would isolate the issue if it was something on his end. it's still blowing fuses. battery terminals are good and clean.
