01-164

Output Diagnostic Test Mode (DTM)
(scan tool function 03), transmissions
with hydraulic regulation -E17-


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 when the engine is
started.
The function of solenoid valves 1 -N88-, 2 -N89-
, 3 -N90- and the solenoids for the selector
lever lock are checked acoustically during the
DTM. Avoid noise in the surrounding area
during the acoustic check, because the
switching noise (clicking) of the actuators is
very quiet.
The solenoid valves 4 -N91-, 5 -N92-, 6 -N93-
and 7 -N94- are activated during the DTM. A
direct functional check of these valves is not
possible. But possible electrical faults which
occur during the activation, will be recognized
by the On Board Diagnostic (OBD) and stored
in the 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.

Kick-down switch -F8

Indicated on display
Notes:

It is not the kick-down switch -F8-, but the switch-off function for the air
conditioner in transmission control module -J217- which is activated. If the kick-down switch is operated, the Transmission Control Module
(TCM) grounds the output to air conditioner. This briefly switches off
the air conditioner compressor. Can be disregarded here. The signal can be checked in measured value block 011 01
