I have attempted to scan my 1996 W210 to find out why my cruise control is not working. Each time I connect the OBDII scanner, the scanner is unable to communicate with the vehicle. I have tried at least 5 different scanners, and they all show the same message. At the same time, I will appreciate anyone who can assist with the reason why my cruise control will not function and what I need to do to fix the problem. Can anyone help?
