Output Diagnostic Test Mode (DTM) (Scan Tool Function 03), Transmissions With Hydraulic Regulation -E17-
Output Diagnostic Test Mode (DTM) (scan tool function 03), transmissions with hydraulic regulation -E17- - 5 Spd. Automatic Transmission 01V
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.
Note:
^ 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.
Test sequence
- Connect VAS 5051 tester or V.A.G 1551 scan tool and enter address word 02 for "Control module for Transmission electronics".
Ignition must be switched off during this process.

Kick-down switch -F8
Indicated on display
Note:
^ 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.
^ Check function of Kick-down switch -F8-.
