Ram Pickup / Ram Cab Chassis (D2, DD, DJ, DP)
This application chart provides documentation for what Service ID $06 OBDMIDs, TIDs, and scaling IDs are implemented in the CM-2200 ECU. The following defines the convention used to determine the required level of support, with the following appreciation being used:
Mandatory (M) 'M' in the column under Service ID $06 indicates that this PID is supported for all applications.
Conditional (C) 'C' indicates that this PID is application-specific and applies only to certain conditional vehicles types, or equipped packages, etc.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
