Output Diagnostic Test Mode (DTM)


Control element diagnosis / Output Diagnostic Test Mode (DTM)
Note:
^ Control element diagnosis can only be performed if the ignition is ON, the selector lever is in position P, the engine is not running and the vehicle is stationary.
^ Control element diagnosis is terminated if the engine is started.
^ Solenoid Valve 1 -N88-, Solenoid Valve 2 -N89, Solenoid Valve 3 -N90-, Pressure Control Valve 1 -N215- and Shift Lock Solenoid -N110- are tested acoustically during control element diagnosis. Ambient noises must be avoided during the acoustical test.
^ Pressure Control Valve 2 -N216-, Pressure Control Valve 3 -N217- and Pressure Control Valve 4 -N218- are energized through control element diagnosis. Acoustical testing is made more difficult by the fact that these valves click very quietly, which can be heard only in the area of the ATF oil pan. However, any electrical faults that occur when the valves are energized are saved in the DTC memory by the On Board Diagnostic (OBD) system.
^ During control element diagnosis the individual actuators are energized for approximately 45 seconds, unless the test is automatically advanced to the next actuator by pressing the > button.
^ To repeat control element diagnosis, switch the ignition OFF and ON again.





Test sequence
- Connect VAS 5051 Vehicle Diagnosis, Measurement- and Information System and in selection touch vehicle system 02 -Transmission Electronics. Ignition must be switched ON.





Display on VAS 5051:
- In selection touch -1- diagnostic function 03 - Control element diagnosis.
- Touch > button





Display on VAS 5051:
A - Actuator test is pending - Test must be advanced
1 - Shift Valve 1 go to Solenoid Valve 1 -N88-
- Touch > button A - Actuator test is running - Test may be advanced
^ This valve is energized (clicks) for approximately 45 seconds, unless the test is automatically advanced to the next actuator by touching the > button

Note: Any electrical malfunctions are saved in the DTC memory = DTC chart starts on.

If the valve is not energized (does not click):
- Perform electrical test
- Touch > button





Display on VAS 5051:

- Touch > button





Display on VAS 5051:
A - Actuator test is pending - Test must be advanced
4 - Shift Lock Solenoid -N110-
- Touch > button.

A - Actuator test is running - Test may be advanced
^ The Shift Lock Solenoid -N110- is triggered at intervals for about 45 seconds (clicks), unless control element diagnosis is terminated by touching the > button

Note: In addition, the brake symbol on the shift mechanism cover must illuminate at intervals.

If the solenoid is not energized (does not click):
- Perform electrical test
- Touch > button





Display on VAS 5051:
