2014 F250 BCM DTC's will not reset

Post by cjfscan1 » Mon Nov 13, 2017 1:00 am

Neither of the DTC's will reset. I have led custom headlights/turn/parking lights where in the past a DTC has shown up and utilizing the FORSCAN tool I have been able to clear the code. This time seems to be different where the BCM DTC's will not reset. The dealer tried as well to no avail. The codes are as follows any help/guidance would be much appreciated.

Four Codes:

U1000 - Solid State Driver Protection Activated
U3000 - Control Module - Addtl Fault Symptom - Internal Electronic Failure
U3003 - Battery Voltage - Addtl Fault Symptom - Circuit Voltage Below Threshold
B123A - Left Front Turn Indicator - Addtl Fault Symptom - Circuit Short to Ground

You sjb is seeing no or less resistance and throwing codes

You sjb is seeing no or less resistance and throwing codes after so many resets it bricks the sjb fuse panel

I have the same issue. Is there a fix?

maybe change the central configuration from normal lights (halogen ) to led lights setting ?
i am the same as you just a forscan user still learning .

Not sure how to do that on a 2013. I know it’s in the BCM on the 2017’s. Can’t find anything for that online any suggestions?

Thanks

think its in the ipc for some models and have to wrtie it too both bcm and ipc threw the central config , sorry just remembered that if you didnt put forscan in engineering mode then the setting will not be seen as they are hidden till eng mode is selected so could still be in the bcm if you didnt change the setting after loading the CC .

Outcome was the BCM was bricked and had to be replaced.

The clue was there, "battery voltage".

Hey guys,

So I am experiencing a very similar issue. A few months ago I installed after market switchbacks as my blinkers (my truck is an XL so I also have after market cab lights and mirrors) all of which ties into my turn signals and running lights going into my BdyCM.

It all started when my passenger side turn signal went out. After checking every fuse, tracking back the wire to the BdyCM, and checking DTCs I found that I had a U1000 Solid State Driver Protection Activated DTC along with a B123A Left Front Turn Indicator DTC. I cleared the DTC and I was able to get the driver side blinker to work but the passenger side blinker was still dead. I decided to ignore it for a while.\

A month later my cab lights started to go in and out (I have a after market remote start that was tapped in after the BdyCM that always flashed the running lights so I knew it wasn't a fuse or wirring issue) with the switch active sometimes my running lights would just shut off.

Checking the DTCs I had
U1000 Solid State Driver Protection Activated
U3000 Control Module
B123A Left Front Turn Indicator
B10F1 Key in Switch

I tried clearing the fault and it would not clear. I originally thought there may have been a short and it wouldn't clear as it was still present so I disconnected all my after market lights and tried again but no luck.

I ran a module self test and there were the same DTCs followed by a few more from the after market HID kit I have

after some digging I found the following on another thread
Field-Effect Transistor (FET) Protection

A Field-Effect Transistor (FET) is a type of transistor that, when used with module software, monitors and controls current flow on module outputs. The FET protection strategy prevents module damage in the event of excessive current flow.

The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a headlamp output circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are shut down when a fault event is detected. A short circuit DTC is stored at the fault event and a cumulative counter is started.

When the demand for the output is no longer present, the module resets the FET protection, allowing the circuit to function. If the circuit is still shorted the next time the driver requests a circuit to activate that has been shut down by a previous short ( FET protection), the FET protection shuts off the circuit again and the cumulative counter advances.

When the excessive circuit load occurs often enough, the module shuts down the output until a repair procedure is carried out. Each FET protected circuit has 3 predefined levels of short circuit tolerance based on the harmful effect of each circuit fault on the FET and the ability of the FET to withstand it. A module lifetime level of fault events is established based upon the durability of the FET . If the total tolerance level is determined to be 600 fault events, the 3 predefined levels would be 200, 400 and 600 fault events.

When a tolerance level is reached, the short circuit DTC that was stored on the first failure cannot be cleared by the clear the continuous DTCs command. The module does not allow this code to be cleared or the circuit restored to normal operation until a successful self-test proves that the fault has been repaired. After the self-test has successfully completed (no on-demand DTCs present), DTC U1000:00 and the associated DTC (the DTC related to the shorted circuit) automatically clears and the circuit function returns. The module never resets the fault event counter to zero and continues to advance the fault event counter as short circuit fault events occur.

If the number of short circuit fault events reach the third level, then DTCs U1000:00 and U3000:49 set along with the associated short circuit DTC. DTC U3000:49 cannot be cleared and the module must be replaced after the repair.

The BCM FET protected output circuits for the turn lamps system are the front turn and mirror turn lamp output circuits.


I am going to try and revert back to the stock lights and then before a module test and see if I can then clear all the DTCs and restore the BdyCM without having to replace it.

I will update this thread with my findings
