Abstract
A control system for electronically controlled vehicle dynamics control systems and ride control systems includes a system ECU and a diagnostics ECU, each having a memory with vehicle parameters stored thereon. When one of the system ECU and the diagnostics ECU is replaced, the other one communicates via a communications link the vehicle parameters stored in the memory thereof to the replaced one of the system ECU and the diagnostics ECU. The vehicle parameters stored on at least one of the system ECU and the diagnostics ECU are user modifiable, and when the vehicle parameters stored on one of the system ECU and the diagnostics ECU are modified by a user, the one of the system ECU and the diagnostics ECU on which the vehicle parameters were modified communicates via the communications link the modified vehicle parameters to the other one.
