2011 RAM 2500 - MM3 P0601

[smartdave]

I have an '11 RAM that I have had tuned since then.

Every year I go back to stock for about 3 weeks, and then retune.

From 11-17 I was using a H&S MiniMax.

Then I switched to a MM3 tuned by folks we know well.

I was purging my ABS module and noticed I have a P0601 pending code.

Everything I have read says the ECU will need to be changed.

However, I have no issues with the truck at all.

Never even knew I had this issue until I saw it on my scanner.

Could this be caused by programming a couple dozen times?

Thoughts?

Thanks
Dave

That's for an internal pcm failure.

Just curious, how old/what is the voltage of your batteries?

Batteries are about 3 years old.

I haven’t checked the voltage but I will.

I would if it were me just to rule it out, these trucks do stupid things when they have weak batteries.

I know they do.

We just had a couple of zero degree days and the truck started fine.

However I will load test the batteries.

I agree check the batteries.

I use to flash a couple dozen times a day so doubt that's anything to do with it.
