Any one knows how to reset the sysytem lmk thanks

[mudman2]

try this

unlock the car, put the key in the lock and turn it 1 click, do not crank it. do not touch anything for more than 90 seconds.

then remove the key and exit

Now try it, don't think this works after one of the many updates, but you may be lucky

For future reference, there is a button combination that resets the PCM. I think its holding down 2,5,8 but would need to dig out an email from my dealer to confirm. It's definitely 3 keys on the keypad.

The combination is: hold down 1 + 4 + 8 simultaneously. Then let go. It will turn off, reset and turn on again
