  1. Anyone experienced codes like these?

    I just replaced both batteries and the issue came back after 400 road miles. Now it happens every time I drive it. 3 occurrences on 14 total road miles today. OBD2 scanner from AutoZone said ABS sensor and Vacuum pump need to be replaced…huh? Ugh, getting pissed at this.
  2. Totally screwed: Installed new Auxiliary Battery and now truck won’t start with multiple errors

    Anyone had to replace any ABS sensors or the vacuum pump yet? Very curious to see if the symptoms you experienced prior to doing so mimicked any part of what I am describing. The auxiliary battery is where most of the advice I received pointed me towards but having swapped both batteries and...
  3. Totally screwed: Installed new Auxiliary Battery and now truck won’t start with multiple errors

    Went through the top. Disconnected primary battery, pulled it out, popped cover to fuse box and removed the 4 bolts (7mm) then lifted the PCM up and there’s a tray there with 3 more bolts (two 10mm and one 7mm), pulled those and lifted tray to find 4 more bolts (10mm) then that real eases a...
  4. Totally screwed: Installed new Auxiliary Battery and now truck won’t start with multiple errors

    Well I just installed a new auxiliary battery last night and have run into several problems since. First was the “anti-theft” code which presented itself on the UConnect screen. You need to have this if you do any work on your battery systems and the only way to get it is from dealer with the...

    Who told you you need to unmarry your Tazer in order to install a new windshield?
  6. Error codes U0001 and U0401 on a 2020 Gladiator Overland

    Very sorry to poach on this forum guys but this information looks really promising at helping me diagnose the codes I have been getting. I am going to drop the glove box and begin checking connections and adding dielectric grease to each connection. However, in addition to this, someone advised...
  7. Anyone experienced codes like these?

    Did you have a loose connection on this CAN Bus or was it a loose screw? Just want to narrow it down .
  8. Anyone experienced codes like these?

    Just curious if these codes and issues would manifest while driving the vehicle. The gauge on the dash says that my battery is betwixt 14.4-14.6 V except when I put the truck in reverse then it dropped to 12.6...WTF? Not sure if it's related and I will still look to replace both batteries but...
  9. AEV 2" Spacer Lift

    1.75” Spidertrax. Keeps the wheels tucked slightly more under fenders and still clears the tires so they don’t rub.
  10. Anyone experienced codes like these?

    I will replace both of the batteries but in my limited understanding the alternator would keep them charged while driving, no? What is a proper voltage reading for a strong battery so I can compare mine please? Also, under the diesel JT platform someone posted a wiring harness out side of the...
  11. Anyone experienced codes like these?

    Once again I am turning to the Gladiator community to help me suss out some major CEL and related issues. I have a 2020 JTR 3.6. The mods I have are an AEV 2.0 spacer lift, BFG KO2 37x12.5 R17 (factory wheels), AEV steering damper and AEV Geometry Correction Brackets. Until a few days ago I was...
  12. AEV 2" Spacer Lift

    Well, I am still loving this combination of the AEV 2.0 spacer and the BFG 37 x 12.5 R17 with Spidertrax spacers and a Tazer JL Mini...the squeak has apparently fixed itself. I say that because it hasn't manifested for over 4 months. I am a bit curious though because with the larger tires and...
  13. AEV 2" Spacer Lift

    I've been watching this thread to see if the OP ever discovered the source of the squeaking when they removed the AEV 2" spacer kit? I know they believed it was from the polyurethane spacers but I never heard if that is what they actually discovered as the problem. I installed the summer 2022...
  14. Hep with a mini Tazer JL

    Except mine did not come with instructions, it came with a card to zautomotive.com/install. I had to print them off, then when I got to page 4. I plugged the two wire bundles into the tazer; then I put vehicle into RUN not ACC, did not start vehicle; then I put the vehicle into AUDIO mode with...
  15. Hep with a mini Tazer JL

    Thanks for all these responses. I have a USB cord that came with my Tazer, I plugged that into my computer and then into my tazer. Then I opened the ZPU.exe Then I hit update to see if new firmware was available (was not). I got a pop up stating, no data was available on my device (blank/not...
  16. Hep with a mini Tazer JL

    I am struggling with this one y’all. The mini is plugged into correct ports, the app has been downloaded but I can’t get the steering wheel controls to function. Please understand that everything was done procedurally and nothing is visibly broken. It really feels like a communication error...
