I have a 2011 Ford F-150 which has been upgraded and there are a lot of after market changes. However after 5 different Ford dealerships, many just side they could not solve the isuues I indicated with them, even when I explained the possibility of a bad BCM. This video actually reenforces what I've been explainng to these service writers. It also allowed me too write notes which I explained to the last dealerships service writer which got a positive write up for action to diagnoses and reprogram or replace the BCM. Thank you!

Both my headlight bulbs blew, no other issues. Is it a BCM issue???

I have almost certainly this issue it's in warranty but seller trying to void it cause expensive. The key's dont work properly, the lock button neither, and battery drain is insane.

I have a 1999 Pontiac Firebird Trans Am. I bought a used BCM from a 2002 Trans Am, but no dealer will reprogram a BCM older than 10 years of age. I called the local car shops and they all say a dealer has to do the reprogramming. Are there any other options?

I have a Nissan Xtrail 2014, and my locks do not work with the remote to lock only the 2 front doors will open but not lock, I have to manually lock them, Once My BCM is reset and reprogrammed. Will that fix the issue? Or I need to buy a completely new BCM?

Warning lights going crazy wipers running with key out . Brother in law hotwired my 2004 saturn ion...bcm elect to the bcm power fuses under the radio.

Very interesting video and information. My question is, what happens when you can't find a replacement example because my Kia Sportage is a 2011 model and Kia no longer produce BCM for my model. Does it mean there are no alternative for BCMs that are no longer available ?? I can't drive my vehicle at nights because I have no lights because of corrosion to the pins/connector of the BCM. Thank you.

I have 2014 Ram 6.7 diesel, it shuts off randomly nobody knows why. Well taken are of 650, 000 miles runs good. Does a bad BCM make it shut down at random times? Used to start back up right away, now the push button stays off for 5 - 7 minutes then it will start again. Cannot rely on it drives a guy crazy!!

I’m having electrical problems, car brake lights stay on when car is on, steering wheel buttons not working, key lock not working nor is the interior lock, is it most likely BCM?

After starting the engine within 1minute Battery symbol coming and Ac getting off because of that. Is this because of Bad BCM.!?

I have a 2013 Ssangyong Stavic - Car has automatic locking at 50kmph. However the car will continue trying to lock the doors after they have already locked. And will then unlock as the car slows down. So car is constantly locking/unlocking the doors while driving. The aircon also works intermittently. Sometimes will be really cold, and other times feels like the heater is on with the same aircon setting. - I also have an electric window on the drivers side which is very slow to go back up. Could these all be symptoms of a faulty BCM?

I have 07 Honda crv.

The green key keeps flashing on the dash.

The code reads the immobilizer is not communicating with the imoes.

A can of clear coat blew up under my steering wheel.

After 6 lock smiths and three mechanics I got that code givin to me by a lock smith. I was told to replace the multi plex control unit which is the fuse box in the driver side cabin under the wheel. I did so and took the old one part and it was saturated on the motherboard. I’m sure it was fried. My question is is this all different from the bcu? It’s going to cost me $100 each time a lock smith attempts to program my key. Should I replace the bcu and the immobilizer and the antenna before I have it programmed ? Ghis has been 3 months now I’m with out my car. Just put the multi unit in tester. Please advise ASAP. Thank u
