Trail & Street Fix for Jeep JKs that have VSC Issues after Installing a Lift KitJune 28th, 2010 by admin
Jeep JKs have a very sophisticated computer monitoring system that does a continuous check while driving to ensure your ABS brake system and the Vehicle Stability System are operating properly. Adding lift kits and larger tires can affect the way the system gets its information.
After installing my lift kit, while driving to get an alignment, my Jeep went nuts. My steering wheel was off center, causing the VSE to engage. The Jeep computer thinks I am turning but the wheels are going straight. It triggers the brakes to apply, throwing the Jeep into an uncontrollable spin. Here is why….
All Jeep JKs have 2 sensors in the steering column. If the steering wheel is off center just a fraction of an inch, it sets the system in motion. The dealership will fix this by aligning the front end, centering the steering wheel, and hooking the Jeep to a DRB tester to clear the code. However, this will cost you a bunch. I have found a backyard remedy that can work even on a trail.
The day I had my Jeep modified I trailed it and went to the Jeep Easter Safari in Moab, Utah. After a week of putting my Jeep through trails like Pritchard Canyon and Moab Rim, my steering wheel was a little off due to suspension settling. While driving to town after one trail, my dash lights started flashing the VSC icon and the inboard side brakes engaged to stop what it thought was a skid. You lose engine power and it feels eerie.
1. I stopped, got under the Jeep, and adjusted the drag link (just a ¼ turn) to straighten my steering wheel.
2. The system is still tripping, so next you have to disconnect the positive side battery cable. Wait less than a minute.
3. Reconnect the battery. Start the engine.
4. Turn left until you hit the steering stops, then turn right and do the same.
5. Next, center the wheel.
6. Then turn off the engine (this sets the computer system to specs where max left and right turn are and straight ahead).
7. Start the Jeep. The icon should go out in a few seconds. I actually did this on the side of the road, after a trail. It WORKS!!
