Greetings!
I just bought a 2005 Magnum. Drove it about 200 miles and decided to turn off MDS (it was driving me nuts).
I first checked the DIAG codes - no codes.
Read the car, turned off MDS, wrote the car.
Started car and rechecked the codes - communication errors between all modules and no CEL on the dash.
Cleared the codes.
Proceeded to drive it 2300 miles home, and dropped it off at my buddies shop.
On the way home, no AC.
My buddy said that he filled it with refrigerant and the compressor is coming on, but not the fan.
He wants to reflash the whole car with stock tune and see if that fixes it.
My question is this - Does disabling MDS usually cause a communication error?
Thanks in advance for your time and responses!
