FAQ

Delphi DCM3.7 DTC codes — frequently asked questions

How many DTC codes does Map Decoder have for the DCM3.7?

223 distinct diagnostic trouble codes, 222 of them with a description.

Where do these codes come from?

Each entry was measured on a real file: the address, the enabled value and the disabled value were read from an original and a modified binary. Nothing here is a generic OBD-II lookup table.

Can these codes be switched off on the DCM3.7?

Yes — Map Decoder writes the value that was observed on this ECU rather than a guessed constant, and corrects the checksum afterwards.

Remove DTC codes on Delphi DCM3.7

Map Decoder analyses Delphi DCM3.7 files, detects the maps and generates a verified patch with the checksum corrected.
