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".
