Output Diagnostic Test Mode (DTM)


Notes:

The DTM can only be performed with the
ignition switched on and the engine not running.
The DTM is terminated if the engine is started
or if an engine speed pulse is detected.
During the DTM, individual control elements will
be activated for approx. 1 minute, or until the
test program is advanced to the next control
element by pressing the button.

The control elements can be tested either by
listening or by touching.
If the DTM is to be repeated, the engine must
be started. The engine control module needs to
detect an engine speed of more than 300 rpm.
The electric fuel pump runs continuously
throughout the DTM.
