Output Diagnostic Test Mode (DTM)
(scan tool function 03), transmissions
with hydraulic regulation -E18/2-


Note:

The Output Diagnostic Test Mode (DTM) can
only be performed when the ignition is switched
off, the selector lever is in position "P", the
engine is not running, and the vehicle is
stationary.
DTM will be terminated if the engine is
started.
The function of solenoid valves 1 -N88-, 2 -N89-
, 3 -N90- and the solenoids for the shift lock are
checked acoustically during DTM. Avoid noise
in the surrounding area during the acoustic
check, because the switching noise (clicking) of
the final controls is very quiet.
The pressure control valves 1 -N215-, 2 -N216-,
3 -N217- and 4 -N218- are activated during
DTM. A direct functional check of these valves
is not possible. But possible electrical faults
which occur during the activation will be
recognized and stored in DTC memory.

When performing the Output Diagnostic Test
Mode (DTM) the individual actuators will be
activated until the button is pressed.

Only one complete DTM is possible after
switching the ignition on. To repeat DTM, the
ignition must be switched off and on again.
