THIS may be DRAINING your Battery Overnight! (Lincoln MKX -Part 2)

This loaded Lincoln MKX has over 30 modules on board, so we need to take a focused scientific data-driven approach to pinpoint this parasitic battery drain problem.
In Part 1 we verified the customer complaint and saw which of the 4 CAN NETWORKS was waking up on its own.
Here in Part 2: I pinpoint exactly which module is the culprit without tearing anything apart :)
For this procedure, you NEED A 4-channel SCOPE, Ammeter, and good wiring diagrams!

Rev up your engines! 30 + modules - holy crap how did we survive with points, no seat belt and 7 ash trays! Mfg's. need to update there software to report better on all these modules as 1 flaw on a network can take out the whole vehicle. Thanks again to Ivan for all these detailed videos..

[@garydowzell6846]

One thing stands out when watching all diagnostics channels on KZbin is that information is absolutely vital to attempt any wiring issues, second only to ability to use said info of course!! brilliant video as always

[@JohnnieBravo1]

Oh thank God you posted the source of the problem tonight. I was already packing up my truck to drive to Pine Hollow from Alabama to find out what the heck was going on with this car! You saved me the trip. (even though it's winter time up there, and I have spent a bunch of wintry days in Western PA, servicing coal mining equipment...... way too cold for a southern boy)

Never have I seen a triple fuse. Not the only one from the comments. Learn something new everyday. The can wires seem to be a twisted pair ? The scope and the circuit diagram is a must along with a multimeter and an experienced brain box 📦. The length of time ⏲ taken to reduce the current is quite substantial taken all factors into account. The newer models are far more sensitive than previous ones and adaptability to different conditions is required. That being said this was a very successful 👏 👌 diagnosis and left the customer with a healthy battery prognosis and an opportunity to drive off into the sunset 🌇.

Perfect logical process of elimination, but as you said, you need the right equipment in order to do that. Another great video. Thank you for taking the time to do such detailed recording of your process.

Ivan,

I still remember how mind blowing voltage drop accross fuses for checking parasitic draws was. Still fascinated by thermal imaging. Watching network activity to determine a draw is new wave!

[@donniejohnson7499]

Retired auto tech here. I always hated parasitic drains especially in newer auto's. Awesome video Ivan. You have some great troubleshooting skills. Scope use in finding it was awesome. Gotta love all the modules,networks . Ii cant imagine in five years. What's next.

[@faxmen09]

Another amazing find/diagnosis. Yeah, no way a dealership would find this problem, too much time/labor/effort for them. Nice job!

[@chetlonczkowski5862]

I've really enjoyed all your videos very informative. I like that you always do the jobs right.

Nice work, Ivan. As you mentioned so many of these modules are problematic and battery hogs. Ford seemed to address this on the new vehicles by shutting down the module at a certain battery voltage. I drive a '22 Transit 3500, with the My Ford app I get a notification that remote features are unavailable due to low voltage after sitting for 2-3 days...but at least it still starts well after a week of sitting. 👍👍

U did such a good job no bonus footage was required !

[@chrissmith7655]

Hi Ivan, cracked it once again, well done. Many thanks for the uploads.

[@ScottDLR]

Nice work Ivan! I probably would have written a little note on the module just in case someone goes looking someday but it's all good.

[@baxrok2.]

Another vehicle saved from the auction block by PHAD. Well done Ivan!

[@R3YNZ]

Awesome diag! I've never thought about using a scope!

[@edwardbella3871]

I will state that dealer techs probably would not fix this problem.Ivan you are at a higher level than most techs. top 5 percent.

[@weshawkins7165]

Fantastic video showing how to prioritize the steps in the diagnosis of this problem. What you call neat and cool other techs dread having to deal with especially dealer techs if the car is under warranty because their not paid more than .5 to diagnose. At least that what it was when I was a dealer tech back in the 80’s.

Hi Ivan

Ford use the exact same BCM on the newer Transit Custom vans.
