Hi all
2012 jeep wk2,, my cruise control wouldn't switch on,,
my solution press on and resume at the same time, it then resets and works
The indicator light comes on and its fine for the day or so
Thanks, I wasn't aware that there was a reset procedure that can be done, that does help....
But, you still have a problem and I suspect that you have a bad control unit in the steering wheel, which several folks have posted replacing it fixed their problem.....
Something not brought out in this long and old thread.....
The cruise control is an interaction of several systems, its not just one single system.....
So those saying the Dealer just replaced their cruise control? I'm like, Huh? which part or did they replace a $1,000 worth of system components to replace everything in the Cruise Control?
I suspect, the Steering Wheel Control unit, which I suspect is also more than switches, it might have a microprocessor in it and communicating on the CAN Bus with messages, is what some of the posters are talking about when they say the whole system was replaced.....
- I'm pretty sure the Cruise Control Functions are all be done by the PCM in the WK2...
- Its get signaled to do so and what speed to hold by the control module in the steering wheel, and to interrupt it with signals from the brake switch....
- There are also faults that it looks for and won't engage the Cruise Control if there is something wrong with the brakes... ...so if you have an ABS warning lamp or brake warning lamp, the Cruise Control will refuse to operate...
My cruise control was refusing to set a speed or drop off the setting it was on, after several hours of use on long highway trips, restarting the vehicle would solve it.
Then the length of time before the fault occurred shortened and it would happen within an hour, and the brake light would turn on when the cruise control would fail to set a speed.... (by fail to set a speed, I mean, I could turn it on, but no matter how much I pressed the set or resume button, the little arrow would not turn on, nor would the vehicle react and hold a certain speed)....
Then I had the brake light come within a few minutes of starting, every time I started the vehicle, to the point the brake light came on within seconds of completing the dash self-test every time I started....
The cruise control refused to set a speed anytime the Brake Warning light was on, I forget if it would turn on or not, because its a pretty moot point if it would turn on but not set a speed....
I replaced the
Brake Pedal Switch, thinking that was the problem, it did not solve the brake warning lamp nor the Cruise Control Issue.... (although mine wasn't bad, I'm confident a bad brake switch would cause these symptoms)....
I replaced the
Brake Master Cylinder Reservoir Low Sensor and it fixed both problems (cause they are related), no more brake warning lamp, cruise control works perfectly...
