Output Diagnostic Test Mode (DTM) (scan tool function 03), transmissions with hydraulic regulation -E18/2-: Notes
NOTE:
- The Output Diagnostic Test Mode will be terminated if the engine is started.
- The Output Diagnostic Test Mode can only be performed when the selector lever is in position "P", the engine is not running and the vehicle is stationary.
- The function of the solenoid valves1 -N88-, 2 -N89-, 3-N90- and the solenoids for the selector lever lock are checked acoustically during the Output Diagnostic Test Mode. 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 valves1 -N215-, 2 -N216-, 3 -N217- and 4 -N218- are activated during the Output Diagnostic Test Mode. 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 the individual actuators will be activated until the --> button is pressed.
- Only one complete Output Diagnostic Test Mode is possible after switching the ignition on. To repeat the Output Diagnostic Test Mode the ignition must be switched off and on again.
