Dreaded engine light..

[Dale's Jeep]

11 codes is just one module. I’m talking about scanning ALL modules for all faults. The answer is usually very clear.

This forum is absolutely fucking obsessed with batteries like it’s the answer to everything. It’s been this way for 7+ years.

Thank You

Sorry, I'm not sure what a shop manual is.

It's that book with pictures and instructions for certain(not all ) repairs for a given year, or years, of a vehicle.

Oh I remember those from a long time ago, haven't seen one in a long time.

That is because the manufacturers don't produce them anymore. You no have to get a CD. It is a PITA.

Purchased 1 year ago.
45k
It's now 90k.

Will be replacing battery soon.

These Jeeps are finicky I tell you.

Not related to your issue, but driving into work yesterday my "service ESC" light came on, I did a little bit of research while on the clock, and had a good idea of what it was. After the lift, my steering wheel was at a slight angle at all times even when going straight, as it turns out their sensors on the Jeep that makes that throw an ESC code. Yesterday afternoon I adjusted the drag link to make the steering wheel straight, at the same time I adjusted the angle for the over axle steering stabilizer I installed a few weeks ago. PROBLEM SOLVED.

I'll be honest, living here in North Texas, my Jeep didn't even make it 2 years/30,000 MI before I need a new battery. We had one hot summer where it was over 100° for 30 plus days in a row and both my battery and the wife's battery (Subaru Forester) died that one summer.

You got 45k miles on that Wrangler of yours, and who knows how many years since that battery was changed. I'm hoping that's all it is for you!

On the plus side, you're probably going to need a new battery soon even if that's not the actual fix for your problem. The downside is, if that's not the fix for your jeep, it's going to get more complicated pretty quick.

When I started having electrical issues last year, I bought a whole new dh7 battery for $350, when that didn't work, I purchased a new battery charge sensor which connects to your negative cable, that was like $45, at the same time I purchased a new can bus which was another $60 off of eBay, and in the end it ended up being a $1 copper battery cable lug!

Going to check all the light wiring on monday.
