FAQ
Siemens SID321 DTC codes — frequently asked questions
How many DTC codes does Map Decoder have for the SID321?
421 distinct diagnostic trouble codes, 241 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 SID321?
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 Siemens SID321
Map Decoder analyses Siemens SID321 files, detects the maps and generates a verified patch with the checksum corrected.
