This was so helpful and so accurate. I have been getting that light pop up intermittently for a few months, and none of the Jeep service centers or other mechanics could tell me why. Because the light didn’t stay on, they said I have to bring it when the lights are active. I found a Jeep genius recently who was able to find the issue immediately without me even asking by reading my codes. He said the exact same thing you said- the vacuum pump. I actually found your video because I'm fact-checking him because my thoughts are, “Why would the vacuum pump be triggering a stability control system light?” But now I see he was right. I wish I could have found this video b4 I paid 2 diagnostic fees for nothing smh.
You good sir! I had to come back to this video to THANK YOU for this video. I had this warning come up recently and I knew it wasn't the aux battery because I replaced it recently. I really want to thank you for listing the troubleshooting steps. I went with the vacuum hose and that immediately did the trick. Extremely easy fix. Saved me money and time! Again THANK YOU!
This Service Electronic Stability Control just came on today after I got my 2020 JL Wrangler back from the Jeep dealership. All I had done was an oil change and tire rotation. I am going to do some troubleshooting today and see what unfolds....Plus my check engine light came on as well.
Can’t imagine an oil change or a tire rotation causing this error to go off. Start with making sure that the fuses in the fuse box under the hood are not loose. The vacuum pump does reside almost directly under the oil filter housing. Perhaps some got on the pump?
Awesome video! I have same lights on, my Jeep guy replaced new vacuum pump, lights were gone for the day, day after they came back. Will got though this. Is it hard to replace the vacuum hose?
ONE BATTERY RARELY FAILS WITHOUT THE OTHER ONE FAILING TOO. CAN BUS BEHIND THE GLOVEBOX CAN HAVE BROKEN CONNECTORS AND CAUSING A COMMUNICATIONS ERROR. Causes the same codes and lights for stability control.
Could be a number of things. I would start with a code scanner to see if anything pops up. If the codes are vacuum related, follow the video here to troubleshoot.
Don’t remove them, just go through the fuse box and make sure that everything is seated properly. In my case, it wasn’t the cause, but Ive oddly heard others running into this issue (especially when you go off-road and bump things around a bit).
@@MotoMaximus I want to go to desert offroading so someboday was saying about fixing kill switch. And its very expensive. But instead we can remove only the fuses only at that offroading time. So do you know which all are they ?
@@midhunmohan2913 the only thing you typically have to do is disable traction control via desired setting inside the cabin, otherwise you can also pull fuse J6 I believe to disable the entire system. I’ve never had to pull the fuse and only used the button inside and done a lot of serious off-roading without issues. 🤘
hi, the problem seems to be similar with my 2018 JL sport s. My auto start stop hasn’t been working so I swapped out and it works great. But now the engine light is on and I’ve had issues where ESC, ABS, service shifter, antilock brake system, traction control, and gear going into pause mode, steering control lock, and etc. brought to dealership and looks like they cleared codes and it’s fine now. Only today I discovered from the reader from autozone saying P0456 (Evap Systemm Small Leak and C1252-92 ( Vacuum Pump Control Circuit performance or Incorrect Operation) is the issue that was found in the code. Do you think this has to do with the Vacuum Pump or the Hose like the video? Thanks.
Is it behaving fine right now? Any lights on dash? If no, I would wait. If the lights are back, test the vacuum pump by unplugging the vacuum line that goes to it and putting your finger over the inlet pipe while the car is running and when the pump activated (it cycles on and off on a regular basis). If there is suction, pump is good, move onto the vacuum line. If there is no suction while pump is activated, vacuum pump should be replaced.
@@MotoMaximus I’m not quite sure. Maybe it’s the gas cap issue and I didn’t close it right. I will have to check on my vehicle I’m purposely not using the vehicle for a week to see if it changes anything. I’m no expert when it comes to vacuum pump and lines. Do you know if there are any videos you can watch regarding this issue with vacuum pump and line problem? any help I’d highly appreciate. Thanks again.
@@j.christopherchang1668 just drive it normally and see if any error codes pop up… I didn’t see other videos on this subject, thus I made this one. I can always do a short one to point out the location of the pump and routing of the vacuum lines..
@@MotoMaximus that would be great. I did goto Autozone and got myself a Fix Finder Report. I found two codes. 1. Replace ESIM (EVAP small leak) 2. Replace Vacuum Pump (control circuit performance or incorrect operation). Now im wondering if I should replace the vacuum pump or just the hose. I will most definitely replace the ESIM Detector its only about $40 on Mopar. Just dont want to spend tons of money going to dealership.
Try the simplest thing first: Start the engine. Center the steering wheel. Turn the steering wheel all the way to the left until the internal stop in the steering gear is met, then turn the. Center the steering wheel.
Hey man, what made you realize this was a vacuum pump issue? I’m getting both lights. I replaced the vacuum booster with an advanced auto parts pump. Hopefully that’s not the problem..I get a bit of acceleration hesitation in highway traffic and when lightly pressing the gas. Any of that sound familiar?
I trolled the forums which all pointed to the vacuum pump, but also suggested testing other things. So I started with simple stuff first and worked my way toward vacuum. I replaced the vacuum pump but the issue persisted, so that’s when I went after a leak in the lines. Once I replaced that, the issue went away. It’s a goofy design to base your TCS on vacuum as that’s typically that’s done via sensors. But, it is what it is.
Did this happen all the time? I only get this error when my 2018 JLU Rubicon is cold. As soon as the engine warms up, if I turn my jeep off and back on the error doesn't come anymore. Do you think I have the same issue you had?
It would come on after I started driving. When starting the car, there would be no lights on the dash, as soon as I would go for a drive they would come on because the system wasn’t seeing enough vacuum to properly control the stability control system.
I have a 2020 jeep wrangler JL and the dashboard is going nuts giving me lights for service shifter, service electronic stability control, auto park disable stop/start unavailable all at the same time. Plus the gearbox light will start to flickering. After turning the car off and turning on again the check engine will come on. I took it to the dealer and they did a software update which they say it would solve the issue but it didn't. Would this troubleshoot steps help me? Has anyone have all those lights go off at the same time?
May wanna try taking off and reseating the fuse box. Also some guys ran into loose connections at the cam bus - the strip of wires behind the glove box.
Replace the green CANBUS block behind the glove box , dealership is expensive but eBay for 20 or 40 bucks. Make sure it's the the 20 slot not the 13 slot
Something happening to my 2019 right now. All the lights going on and off randomly. It locked up once and wouldn't go into gear. Been in the dealership twice and they can't fix it. Any update on yours? Get it fixed?
@@MotoMaximus I’m getting stability A light and check engine I replace the ground from block that Jeep ripped I’m waiting for the vaccum line hopefully that works
@@Bigpimp6969.. take current line off at the vacuum pump and put your finger on the inlet of the pump, if when the pump activated you feel suction, pump is good, if not, suspect the pump. Mine was good. If vacuum like doesn’t fix it after that, try that sensor by the brake booster. There is a good chance that the line is defective. I don’t understand why they used that stupid plastic line with o-rings inside instead of simple high pressure, rubber lines. Stupid cost cutting =)
68053596AA nothing wrong with using aftermarket stuff, but you may as well use OEM mopar parts since there shouldn’t be much of a price difference. The only exception is the pump, which may be harder to get in OEM and will be pricier. Chances are, the pump is fine.. simply start the car, unplug the vacuum line, put your finger over the intake line to the pump and wait for it to kick on. If there is suction, then it should be fine.
I have the same blue gladiator, only has 32K. However, my jeep just goes into limp mode and the esc comes on and the truck just shut off!! and wont restart and and i have to tow it to the dealership every time!!. I have only changed the from bumper only on my jeep so far. I do believe the steering is slightly off a bit. My question is can the esc light cause the jeep into limp mode and just shut off for safety reasons etc. I need help!!!
No I don’t think the ESC is the issue in your case. Some folks spoke about having a loose cradle for the fuses, which may be the issue. What’s the starting issue like? Cranking but won’t fire or won’t even crank?
