How to Reset the Battery Monitor on a Modern Vehicle

I will add that in 2019 there was a recall to address a bad ground connection between the battery and a ground screw on the left side fender caused by paint. This required disconnecting the ground wire at the fender, cleaning the mounting bolt, and reconnecting.

I have found that the remaining ground points on the fenders and radiator support can suffer from the same problem. I proactively cleaned all of them and used an anti-oxidant grease when reassembling them. Have not had any electrical glitches.

Checked all grounds on fenders, all test .2 ohms or less. Going to try the IBS reset procedure, see if that helps. Will post results

I'm not sure how you measured it or what kind of meter you were using, but two-tenths ( 0.2 ) of an ohm across the connection point seems a little high to me. I just measured mine with a Simpson digital meter from negative battery terminal to all fender and radiator support ground terminals and got 000.0 ohms on the lowest scale.

If you are still having issues with your truck swing on down to sylvan lake and I can take a look if you want.
I got a few good scan tools that can look at the entire truck modules.

Sorry. Disregard my previous message. Missed the word "all." If you are getting the same reading across all ground terminals, it is probably the meter calibration, not the actual resistance.

Appreciate that skuppy. I may take you up on that. As I previously stated, checked all the grounds and just performed an IBS reset on the truck. Only have two drives on it since but not hopeful

I really don’t think it’s a ground.
If it was a ground it would have been a problem before your battery died.
Sure i should be around this Saturday.
Pm me and we can exchange contact info.
Cheers

BIG shout out to skuppy069. Got me up and running again with NO MIL on the dash. Thanks again skuppy069, and please thank Roman for his help as well.

 

[skuppy069]

What was the issue?

What was the issue?

A bunch of modules on the truck where not happy as the abs module lost its mind.
Had to do a few procedures to get it calibrated .
Electric park brake,sensors and a few other things had to get relearnt .
Then had to take it out of plant mode.
Then cleared all dtc again and was good to go.
Very strange how it got so scrambled but it was dead and boosted on a hill so maybe when it got Boosted the data from the ORC was not passing and threw it off.
