Output Diagnostic Test Mode (DTM) (Scan Tool Function 03), Transmissions With Hydraulic Regulation -E18/2-
Output Diagnostic Test Mode (DTM) (scan tool function 03), transmissions with hydraulic regulation -E18/2- - 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 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.
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.
