2013 F150 BCM Failures Pt. 2 Continued Testing...

[@WolfChrisCraftScorpion]

I have a 2013 Ford F150 5.0 XLT CrewCab 4x4. Same issues began occurring when the truck hit 150K miles. Pulled codes 3 codes: U1000 Communican Bus Fault B132B Left Stop Circuit short to Ground B132C Right Stop Circuit short to Ground. Both Tail an Brake lights were not working. I do have after market LEDs but with resistors installed and the connections were made using weather tight connectors. I cleared the codes, and started going after the grounds. I cleaned the battery grounds, pillar grounds [both sides] and cleaned the ground above the spare tire for some Fuel Module. Used electronic cleaner, wire brush, roughed up surface, and applied dialectric grease for protection. Waited not more than day and boom I got more codes. Same short circuit grounds but this time no U1000 Communication Bus Fault. There is also now a new Power Steering Control Module U3003 Circuit Voltage below Threshold. Again LED's can and will cause this. So I switched back to incadescent light bulbs. Cleared Codes: Try again. Boom Codes again for faulty grounds on both turn signals. At this point I am going to do your Diode fix on those wires and see what I get. Ill post results. will take a week with work life. Love your videos, they have helped me. I will send you a 12-pack

[@PhillipBailey]

Don't waste your time with the diode it won't fix your issue. Your BCM is seeing too much current on the brake light circuits. Try unplugging the rear harness behind the rear bumper, clear the codes, apply the brake and then rescan the bcm codes. If they don't come back your rear harness is shorted somewhere. I'd be looking at where you connected the LED resistors to start with. I would not worry too much about the low voltage code as likely the battery is low if your not using a clean battery charger during testing.

Phillip, AWESOME/ INTRESTING problem and bravo for staying with it with ur LOGIC thinking and some patient hope this is a good fix enjoyable as always to learn from the master hope will see the follow up soon thankyou. cheeeeeers Brother

Very interesting issue and logic! Looking forward to your next video and wishing you all the best in finding a solution!

[@04NickySP2]

Thanks for posting this troubleshooting. I'm currently chasing down b123a & b123b. Neither front turn signal works and I'm about at the point to replacing the BCM and reprogramming with forscan.

[@PhillipBailey]

Those codes are for the front turn and mirror indicators. There should be a two digit suffix code attached like 11 or 15. Are the signal indicators always on or not working? What have you done to try to remedy this problem. Did you modify the turn signals or mirrors.

[@slowpoke96Z28]

You should consult with the Ford house and show them your findings. Both for tech education and maybe better manufacturing practices.

[@michaelr.williams8176]

Their is also ground on the fire wall and also under the body fram near the passenger door and also under the fire wall is the passenger wheel mounted to the body fram

[@moonslivers]

Great video. One question, trying to do similar on a basket case that did not have BCM. I have used BCM from junk yard. Any lead on how to reprogram without the old BCM to copy?

[@PhillipBailey]

You have to use Ford Service Programming and as built data from Ford. Make sure you have the correct BCM. You need the vin from the donor truck to check the part number is correct and matches your part number for your vin. The numbers on the bcm don't work...

[@ronaldfrazier1127]

[@JonHolovach]

Hey did the problem stay away with the bcm replacement and diode? I have a 2013 f150 with the same issues on bcm number 2 and the problem has come back in 2 months. Low voltage on the hazzard circuit again.

[@PhillipBailey]

Yes the problem seems to be fixed as it hasn't acted up since the last BCM. Unfortunately I can't be sure what fixed it. I cleaned 3 grounds under the dash, one on each A pillar and one on the steering column. Also cleaned 2 grounds on the right inner fender near the battery plus had the entire dash, seats and flooring out of the truck. Sorry wish I knew what the root cause is/was. It appears to be a fairly common issue where the internal 8volt source is lost to all the pull down circuits.

[@gbierfreund]

Did you found the reason? Thanks for your answer. Does the truck have multifunctional seats?

[@PhillipBailey]

@gbierfreund we will never know for sure what was killing the BCMs. In the part 3 video I took the dash completely out, cleaned a bunch of grounds and installed a clamping diode on the gear shift lock solenoid. So not sure what fixed it. No normal seats.

[@davidellenbaum1229]

have you looked @ mode motor heater/a/c motors - blower motor amp draw while in operation also check door lock motor draw. and one other thing we have had numerous radio problems

[@PhillipBailey]

Thanks but what kind of radio problems if I can ask?

[@wood123firebird]

just caught this video, very good, you seem you have a really in depth understanding and great catch comparing the col. shift vs. floor shift. I have similar problems on my 2016 king ranch with a floor shift. did the addition of the diode actually fix your issue?

[@PhillipBailey]

I can't really say for sure but as I mentioned in the video the floor shift does have a clamping diode in the circuit. I would recommend to clean all the grounds in the dash on both A pillars behind the plastic trim left and right side and the body grounds on the right inner fender by the battery. so far this thing has not failed again since but I don't really know what fixed it. Did your BCM fail with the same symptoms? Hazards on for no reason, low brake fluid message on the dash, power locks not responding from their door switches but work from remote?

[@wood123firebird]

@@PhillipBailey I actually did find that water ran down the harness to the middle top connector on the bcm and now all the pins are corroded. just dropped it off at the dealer today since they just installed a new bcm a few months ago. i am hoping they can find the leak.

Awesome awesome videos, I have a 2012 raptor with the same issue- door locks, low brake fluid, e brake, 4 ways were on/ now don’t work. I have a Center shift console, would you recommend to change the shift lock solenoid ( I believe it’s part of the whole shifter ass.) I cleaned all the grounds already, and checked as many connectors as I could.

[@PhillipBailey]

Have you replaced the BCM already? I'll never know for sure if the diode I installed fixed this truck or it was cleaning the grounds that fixed it. Be sure to clean the two grounds by the battery. The console shifter lockout solenoid is supposed to have a clamping diode.in it.if you don't have a graphing meter it would be impossible to see the spike if it's present. Might not be a bad idea to change the solenoid to be safe. Keep me posted if you can. Good luck.

[@PhillipBailey]

The U codes are communication codes between modules. Which modules are you reading these codes in? I thinking the BCM? Bad grounds can cause all kinds of issues. Start by cleaning them and make sure your battery is good and alternator is charging correctly. Do a complete network code clear, start drive and operate accessories then do another network code read to see what comes back.

Great video how did you fix the fan controller? I am having same issue.

[@PhillipBailey]

The fan and heater controls were acting this way due to the wrong BCM in the vehicle. I put the correct one in and programmed it to the truck. Did you change your BCM?

Thank you for your beautiful videos I have a question I have the same problem The dealer told me to replace the BCM And I would like to tell you what I am thinking, causing problem I have water leaking on the third brake lights Also, I put LED lights highbeam, low beam, foggy light and I put off-road light connected to the battery Do you think this is the causing problems that thing that killed the bcm ? Or it’s another thing I just want to be careful before, but the new bcm Thank you so much for your time Hopefully I get answer

[@PhillipBailey]

Good day and thanks for watching my videos. By third brake light I'm thinking you are referring to the high mounted brake light on the back of the cab. A leak in that area should not get the BCM wet as its in the right A pillar area. Also LED lights may set fault codes but should not damage the BCM. What exactly are your symptoms? If you replace the BCM be sure to clean all the body grounds. There are one on each side A pillar under the dash and two under the hood beside the battery on the right inner fender.

[@PhillipBailey]

@juanpaulobustospacheco4204 so if the driver side front door lock button does not cause the doors to all lock or unlock but everything works from the other side I'd suggest that there are broken wires between the door and A pillar. At the door switch you should measure 10 to 12v on the blue/green and yel/violet wires pins 4 and 3. If you do try grounding each with a conventional test light to ground. The locks should lock when the blue/green wire is grounded and unlock when the yellow/violet wire is grounded. If there is no voltage on either you have two open wires. If voltage and they respond to the test light check the ground on the black/violet wire at the switch pin 2. The backlighting in the switch will not work if you have no ground to the switch. Good luck

I have 2013 f150 with a failed bcm. First I wanna know why it happened. I have had multiple dead batteries and read that low voltage could kill it, I had some aftermarket lights that shorted out also. Anyway the second thing is what part number. I can see in for scan the assigned part number or whatever but do I need one with the same number as that or what? I also don’t have access to ford ids but read somewhere pats can be programmed with for scan. Thanks In advance.

[@PhillipBailey]

How did the BCM fail? What were the symptoms? I am not familiar with For Scan so I can't speak to it's capabilities or weather it can read the part number. I do know that you can't go by the external tagged number. I had to compare the dealer part number by vin from potential donor vehicles. As to why they fail? Possibly bad grounds...there are two main grounds under the dash on the left and right A pillars and a couple on the right inner fender near the battery. A bad alternator can do it too. Incorrect boosting, charging and water intrusion.

[@calvinmarsh474]

@@PhillipBailey First symptom was when I started having continuous memory dtc’s. For scan is pretty much an advance scan tool software for a pc that you can use to change parameters and do live data streaming, clear codes, reset modules, module tests, etc. it’s really pretty neat for the price point. You can also change the modules as built data, which I did to disable hyper flash when I had led bulbs in. Well I had a short somewhere, and kept manually clearing the code until it wouldn’t clear anymore. Then I got multiple codes in the bcm from internal electronic failure to key in switch circuit short to ground, and more. They are permanent codes now. Lost power seat function last week, remote start quit, battery drain. Thanks again for the help
