this computer replacement was for an ECM, also called PCM. A BCM controls more minor things and is separate from the ECM. It does stuff like headlights and door locks and Ac controls.

Thank you so much! So my car was throwing out false codes. After a few mechanics and MUCH money spent on parts and labor it turned out that my used car had previously had it's computer replaced from the wrong model car. You saved me extra hassle and money. Went to the junkyard and fixed it myself!

[scottykilmer]

I used a small salvage yard that specializes in imports. But computers that are bad can have thousands of different symptoms, it's often very hard to accurately diagnose a bad one

Scotty, thanks to you I was able to repair an overheating problem in my 03 impala because of watching some of your videos. And now I'm fixing to repair a cooling fan assembly, just wanted to say thanks for your videos.

Hey Scotty. turns out all my car troubles were because of a bad computer. Well thats what the mechanic at the GM place said. however the knowledge I gained through testing everything about the car is invaluable and I can't thank you enough for helping me throughout the way. I' just pulled the computer out of the car and I'm working on getting a new one now

[jackfenn]

Scotty, I hear you live so far back in them thar Tennessee hills, the BANJO music stopped 20 miles back! You live so far back, you have to pump in sunshine, (but pump out moonshine!) (What you don't drink, that is!) You are a great American, and one of a kind! Love all your videos!

Why Scottie Kilmer so articulate and delivers very briefly that even a Slow learners and Retards could understand him???..He's just the Best Mechanic Teacher out there ever.

[DKLLA]

love your videos!
i will be writing my red seal test this year

[amunderdog]

Just like always:)
The diagnosis was the difficult part.
Many mechanic would have just started throwing parts at it.

Good stuff. I had to mine and discovered that Bosch ME 11 or 7.1 computers are interchangeable to an extent even with slightly different codes. It was a gamble but it worked. Fuel map was slightly different though, but I got more low end power.

[jonathanmonger]

I have no regret following you for years.

[sawajiri]

That's why I liked Scotty kilmer video straight to the point

Hello there Scotty, I am a follow of yours and really enjoy everything that you taught us throughout the years. My question for you is I have a 2006 Grand Jeep Cherokee and I believe the PCM has a short in it I'm going to swap it out with one with the same numbers but my question is do with that need to be reprogram?

[syedjawadkarim]

Hi scotty..

For a 2012 Nissan Altima 2.5 ECM or TCM replacement... is there any reprogramming required if used computers are the ones replacing the original if both have same serial numbers?

[MonteOlsen]

Another great one. Who would have thought a bad computer could cause that problem?

[GhostFleetServices]

Scotty, i have a tool question. You have any recommendation on tools brands? I was thinking about buying a 1/2" Snap On Air Impact. (MG-725). Would you go for it, or avoid it? I figure an impact isn't something i should "cheap out" on.
