I love this. Reminds me of back in the day when they would run bad hot and you used a spray bottle to cool down ignition module and the car would run fine. Great job. Fixed is fixed.

[@arthurfricchione8119]

Interesting fix although I have seen many times boxes or components in my field of knowledge be affected by heat and cold . Glad to see it worked out for you. Thanks for keeping us updated and you and family have an enjoyable weekend. 😊

[@BrianMann216]

Yeah I am glad too. I have had some faults with othe older style ( late 90s) that this testing led the way. Have a good weekend. 👍

[@ASEMasterTech909]

Great diag! I use a vortex tube, uses shop air, blow cold on one side and hot on the other. Either way you did a hell of a diagnostic.

Fantastic video master

[@DJ-tn7vj]

Yo old school ice box trick. Thanks B. Nice one

[@djosbun]

This was a fantastic video, Brian. I appreciate your skills in relaying your diagnostic process with us. I’m about to start my module programming service, so I’m trying to absorb as much as possible (and will probably be joining your membership program).

[@BrianMann216]

Thanks for watching, best of luck on the programming business, 👍 where are u located?

[@djosbun]

Awesome video as always. I really enjoy watching these on my day off. WHAT VIDEO RECORDING SOFTWARE DO YOU USE?

[@BrianMann216]

For screen recording I use OBS , editing I have been using premier pro for last few years ,but I am switching to DaVinci

[@daviddasilva4897]

Brian to cool down use a fridge or they sell some spray to clean computers that is very cold

[@BrianMann216]

Yeah the fridge worked , I was just trying to show(for myself) without disturbing/ unplugging the ecm .. the can spray would probably do it, was thinking about cracking a referral container like the old days🤔🤣

[@philh9238]

That’s totally opposite of what I had on a 2010 mustang it worked cold but heated up did exactly the same thing with the maf

[@BrianMann216]

I am really wondering what exactly the failure point is within the ECM.

[@billsmith2212]

CRC makes a Freeze Spray . - 60° F . You can probably find some competitors if it's not available locally . Dry Ice may be another option . Great diagnosis and fix .

[@TheRallyCoop]

Another great video. Can you advise the make and model of the laptop stand you used in the video?

[@BrianMann216]

Professional Adjustable 32.3” - 52” Laptop DJ Mixer Tripod Stand | Lightweight & Portable 15.3” x 12.2” Tilted Tri-Pod Tray for Processors, Audio Controllers & Tablets | Raised Edges for Protection a.co/d/gug7XHw

[@mrblonde2013]

I am pretty sure there is some cold spray in a can for situations like this. My question is : what made you decide to put the pcm in the fridge? Experience or was it some other clue? Is there a pcm data pid for internal pcm temperature?

[@BrianMann216]

Maf signal at the pcm and the maf the same with no increase in frequency had me thinking it had ti be inside the pcm. It was cold outside the 1st time it acted up for me for a while. At one point I realized I was out of options and went old school..

[@johnbonifas6040]

Nice diagnostic work Brian where do I what website do I go on to sign up to your program

[@nickhyslop5743]

Got some bad solder? Old school computer guys would throw boards in the oven to reflow solder

[@stevenayala2324]

2 cans of air would work to cool it down!

[@tracycolorado]

Another tool for the tool box . Dry ice. 🧊
