2019 2.0 jlu cel and esc warnings

[Dyzard10]

Not sure where to post this but kind of at a loss and hoping someone can point in the right direction.

Esc light came on and shortly after the cel came on.

Wife was driving it and seemed to have a loss of power and I checked the voltage of the battery and it was telling me 12.2 I revved it up and it went back up to 14.2

I then turned it off and it seemed to slowly turn off not the usual just off you get.

We were able to drive it the five minutes home and today I check the codes and get
p061a internal control module torque performance
P0562 system voltage low
P0562-00 system voltage low

C006A-28 multi axis acceleration sensor

Nothing crazy is happening, engine is running fine it turns fine, it drives just like normal. Had battery tested and it's good checked all the fuses and they're good checked the array its all good

When hooked up battery codes were gone for 5 minutes then esc came back

Turn it off back on cel is back

When turned on it'll be at 14.2 volts turn off and immediately back on and battery reads at 12.2 every time
(Which throws the system low voltage)
Auxiliary battery doesn't exist for those that go to point at that

Other things I'm finding in research is the vacuum pump or sensor could throw this stuff or the pcm itself.

Any thoughts or recommendations would be helpful

Many problems come from a worn battery but which still allows starting. MY 2019 and maybe battery manufactured in 2018 . I have a MY2018 model manufactured in July, I just changed the 2 batteries (AGM). 6 years is good for car batteries. They started the Jeep, but many errors have disappeared since then!

12.2 volts is only about 60% charged; should be 12.6 to 12.8 with engine off. Charge battery fully and load test. My guess is your battery is toast and causing your issues.

If the batter(ies) in your '19 are the original(s), replace them as a prophylactic measure. Seemingly unrelated electrical issues, such as what you've experienced, are a classic symptom of an automotive battery nearing the end of its practical service life. When AGMs go, they tend to go quickly, so additional warnings, so to speak, might not be in the cards before complete failure occurs.

How was the battery tested? Its resting voltage, which should be no less than 12.3V, can appear acceptable, and then fall off a cliff during a cranking event. It's the latter that really serves to illustrate how healthy a battery is, or isn't.

 

[Dyzard10]

the battery was tested by taking it to autozone and them doing their battery test thing and saying it was still a good battery.

 

[alphawolff]

I don't really care what autozone says. You probably have a failing battery. You should replace them before continuing with a low voltage DTC present. Normal battery voltage range with the engine running is 12.6-14.6. Anything in that ballpark is OK when the engine is running. Just because a battery can charge and pass a load test does not mean it can properly store a charge.

There's also a TSB to update the PCM for the P061A DTC.

 

[Dyzard10]

alrighty well I know what I am doing then tomorrow new battery, and alignment as that is due as it is. for the TSB flashing do i just need to call local dealership and say I may need a PCM flash and bring up the TSB?

 

[Dyzard10]

as well with this TSB does that mean jeep will flash the PCM for free ?

Not necessarily. Recalls and TSBs are separate and distinct, in terms of what the customer will be responsible for in such matters. Generally, owners will have to fund parts and/or labor costs associated with TSBs. Certainly you can ask the dealer for some goodwill consideration here, if or when you're presented with an invoice.

Makes sense to me
