EcmSpy - ECM Error Codes

ECM Error Codes

Errors are stored in the various error bytes. Depending on the DDFI version up to three different error types will be shown:

Current errors are set when an error is currently present, like a broken wire, that hasn't been fixed yet.
Recent errors occured on the last ride, but are not present any more (e.g. raised by a slack joint) and will be cleared once the ECM is powered down.
Historic errors are stored in the non-volatile memory of the ECM until they get cleared with the software.

For XB models, the errors are grouped into Diagnostic Trouble Codes, which help identifying the faulty device (e.g. temperatur sensor). Most trouble codes therefore cover quite opposite errors, as a too low or a too high voltage. The EcmSpy software will decode the actual error from the error byte (as shown below) and provide you with a clear text error message too.
