General






The transmission control module (TCM) can be read off manually using the flashing code sequences, this however means relatively long flashing sequences for each incident. In contrast, using the facilities available in the ST, the TCM can be read off ten times faster. High speed activation occurs in approx. 10 seconds. After this initial period each operation takes only a few seconds to complete.


Depending on the system module to be activated the following abbreviations appear in the text display on the ST:
