Diagnostic software and interfaces for Detroit Diesel engines, covering fault codes, parameter settings, service routines and powertrain ECU reprogramming across CPC, MCM, ACM and D12 TCM controllers. Most workshops start with Detroit DiagnosticLink Pro, the professional edition that allows reprogramming rather than read-only diagnosis. You will also need an RP1210-compatible interface – ask us and we will match one to the trucks you run.
