Erasing diagnostic trouble code (DTC)

Hint: The transmission control module (TCM) has registered an internal fault. The fault can be of intermittent nature, so the diagnostic trouble code (DTC) should be deleted and read again.

Note! Erasing will delete all the stored diagnostic trouble codes (DTC) with any associated information. If there are any other diagnostic trouble codes (DTC) present for the transmission control module (TCM), they should be investigated first. If necessary, go to Car Communication and read off "Extended diagnostic trouble code (DTC) information".




- Ignition on
- Erase diagnostic trouble code (DTC) by clicking the VCT2000 symbol.










Continue - Reading off diagnostic trouble codes (DTCs)

-------------------------------------------------

Reading off diagnostic trouble codes (DTCs)




- Ignition off
- Wait for two minutes so that the diagnostic trouble codes (DTC) can be stored in memory in the transmission control module (TCM).
- Ignition on
- Read out diagnostic trouble codes by clicking the VCT2000 symbol.









Are there any diagnostic trouble codes (DTC) still stored?

Yes - Control module replacement and programming

No - DONE
