Can anyone tell me how to enable the self diagnostic mode on an '03 Escalade?
The service ride control message came on and I want to know what the problem is before taking the truck to a dealer.
Ive read about how to enter diagnostic mode on older models, but my DIC has no on/off button nor up arrow.
Thanks
