Jeep JL 2.0 Dashboard Issues

[Geradio95]

So today I went to buy two batteries.

For the main: https://www.walmart.com/ip/EverStar...CCA-140-RC/40685088?athbdg=L1102&from=/search

and AUX: https://www.batteriesplus.com/productdetails/slipsaux14


When I went to replace the AUX I found that my JL 2.0 didn’t have one. So after I replaced the main battery, my jeep turned on, but the dashboard didn’t, at all. Everything else is working with no issues. Has anyone dealt with this before? What can I do? I tried adjusting the fuse box but haven’t had any luck. Thanks in advance.

Adjusting the fuse box?

Adjusting the fuse box?

I meant putting everything correctly. I’ve read that for a couple other people they’ve had to push down the fuse box/fuses.

Ok, pushing the fuses all the way in is not a bad idea. Did everything work before the battery swap? Did you try to crank it with a dead battery? Does it start and run just no dash display?

The instrument cluster worked previously and stopped working after the swap. It didn’t work when the old battery was swapped in. Yes, it runs and everything works well.

Check fuse F105. Does the AC control work?

The AC works. I will have to give it a go on the off chance. Will update!

Man, there has been more than one thread here and the Gladiator forum on dashboards going black. Does the tach and speedo work or is there nothing?

Are you sure you don't have an AUX battery?

If you don't, then you have an eTorque. You have a large secondary battery to power the system.

Unfortunately, there is nothing but black. It could need to be cycled or it could be that the fuses need replacing or worse case scenario the instrument cluster is a bust.

Yes, I do have etorque but didn’t know it didn’t have an aux battery.

Oh Okay, the eTorque Jeeps have a regular car battery and a second large hybrid style battery under the rear seat.

You are correct. No smaller Aux battery.

You should check the fuses and make sure none of them are blown. Maybe there's a replacement procedure because of th secondary eTorque battery.

Have you checked the dash display fuse? There are wiring diagrams in the Elect sub forum. Look for burned fuses in the PDC.

I changed the fuses to be safe but no luck. Maybe the car needs a few cycles before clearing up, but thankfully I’m still under warranty so I scheduled a trip to the dealer tomorrow.

Will do that! Hopefully it’s not the Z fuse itself.
