  1. Wobble Without A Cause

    I have encountered the harmonic oscillation (wobble) a couple times. I have a Sport S JL ‘18, no structure mods, 3.6L A/trans. While it is alarming at any speed, to my knowledge, no one has ever died from it. As long as one does not surrender control, then the vehicle can be slowed to a safe...
  2. Do I need IBS if no Aux Battery?

    Vehicle is a 2018 JL Sport w/3.6l Auto Trans. Aux battery removed. Aux POS reconnected to Main POS. Aux NEG taped off. No other system mods. Sometimes, after removing the charger, the dash Battery Voltage gauge reads a steady 12.7 (while driving) for a day or two. There is the occasional...
  3. Battery Trickle Charge & Warning Light

    1. Should a trickle charge connect to the negative post directly (bypass IBS) or should it connect so the charge will pass through the IBS? Does the IBS care? 2. If there is a charging problem, the red Battery Charge Warning Light should turn on. Where in the dash display is that light? Is...
  4. Tire Pressure Question for Tire Experts

    I live in a SoCal desert where there is a 30 deg swing in temperature from sunrise to sunset. If I set my tires to the recommended 36 psi “cold tire” setting, then half the day they run at 40 to 41 psi. Of the two evils, which is worse? Running the tire under or over pressure? Is the...
  5. UConnect 4 7" Version

    How do I find the version number for the UC 7" on my 2018 JL? The procedure for the 8.4" does not work on the 7". Anyone know how to do this? Thanks.
  6. No Aux Batteries Available to Buy?

    I wanted to replace the Aux battery (2018/3.6/ESS) and cannot find any for sale. I live in SoCal and no auto stores have any at the store or in their warehouse within 50+ miles. Are other areas in the same shortage? Thanks.
  7. Experienced Battery Advice Wanted

    I have a 2018 JL Sport, 3.6L, ESS, AutoTrans. Build date July 2018, purchased Nov 2018. All TSB updates applied. Currently 14K miles. New main and aux batteries March 2020. When new batteries installed, I had to trickle charge every 4 weeks. That is because I average about 550 miles per...
  8. Fender Flare Clips

    The supply for JL fender flare clips (OMIX FENDER FLARE CLIP W-TYPE 9.90 JL/JT 11609.41 ) is delayed and the earliest date I can find is April from Quadratec. Researching the same clip for the JK model shows that they "almost" look alike. Has anyone ever used both and will the JK version...
  9. Wiring Diagram Confusion

    I am trying to wire up the GemPro side flashers. The “instructions” state to wire the side marker to the Beige/Orange wire. The wiring diagram (available on this site and attached) shows three BG/OG wires in the Park Lamp System. Two of those wires are in clusters that have Premium included...
  10. TPMS Re-education

    Is it possible to change the triggering PSI for a low tire pressure in the TPMS? I don't know if that is in the vehicle or in the tire valve. Any insight would be appreciated. Thanks.
  11. A/C Air Mix Question

    Does the a/c mix heater air to achieve the set temperature (and then send it out the vents) or does it cycle in and out to maintain the set temp in the cabin? Thanks.
  12. Mapping the Battery Cables

    I am trying to isolate my Aux battery so that I can separately charge it to determine if it needs replacement. I do not know which cable is which and could not find the info in the forums. Can anyone identify the six cables? Thanks.
  13. JL Door Weight

    I was casually asked about the weight of a front door on my Sport S. The manual only indicates that they are heavy. Heavy is different for different people. I have never removed the doors and was curious if anyone had a feel for the weight of the doors. Thanks.
  14. Tire placement question.

    Let's say I have four equally worn tires at about 15k miles each. I go four-wheel drive off hard road for 5 to 7 miles. One tire needs to be replaced by the spare. The spare has very little wear so it is slightly bigger. I have to 4-wheel 5 to 7 miles back to a hard road. Which tire...
  15. Blind Spot Lamp Wiring addition; In series or in parallel?

    I am trying to install a second Blind Spot Indicator Lamp for Driver and Passenger side. The attached wiring diagram shows a Lamp-Blind Spot Indicator-Driver (the 'Driver' referenced is not a reference to the Left side of the Jeep but to the bulb.) For the Driver (left side) it is a...
  16. Trickle Charging Procedure

    1. Should the negative (black) connector from the charger unit attach at the frame grounding bolt or at the clamping bolt for the negative post on the body? Looking at the wiring diagram, the difference would be the inclusion or exclusion of the IBS during the charge. It might be moot but I...
  17. JL Evaporative Canister Purge Valve

    I need to replace my purge valve but I cannot find it. All the YT videos show the location on JKs and earlier but not JL. Does anyone know where this valve is located? Thanks.
  18. Persistent Battery Charging

    I persistently get a "Stop/Start Not Ready Battery Charging" message on the Stop/Start screen. I do not get any other messages on any other screens. The battery charge with engine off reads 12.6 and the battery/alt voltage while driving reads between 14.1 and 14.3. I have charged both...
  19. Android Auto Wireless to UConnect Systems

    Google has announced that a recent upgrade to Android Auto (4.7) will now fully connect to Android Auto capable head units, eliminating the need for any wired connection to access all features. Does anyone know if UConnect (5, 7, and/or 8") will work with the update or if UConnect intends to...
  20. Default to Mute

    Is there a way to set Mute as the default so that the radio is in Mute at start-up? I am guessing there is some sort of magic incantation that needs to be performed. I just have not found it. Thanks.
