I have a 2009 LMM and my elevated idle will not turn ON. I have used both the DIC to try and turn it on and also pressed the gas in and tap the brake 3 times. It will pop up saying elevated idle but WILL NOT switch to the ON setting. Continually says OFF after trying each process. My check engine light is ON. Does this happen to screw with the elevated idle and stop it from going on?
LMM elevated idle will not turn on
- Thread starter Chadball
- Start date
Depending on the code it will interfere yes. should be abe to make it stay on threw the dic are you doing it right?
I don't have a lmm around at the moment you don't hit the check mark to switch it to on im trying to remember how to do it look threw owners manual it should show the process ill see if I can get ahold of a lmm to do it
It's through the fuel and brake pedal as the op stated.
Without looking at the manual myself I can't remember.
Op if you don't have a manual I think there's a you tube video on it.
Or at least there used to be.
