Output Diagnosis Test Mode (DTM)


Output Diagnostic Test Mode (DTM)(scan tool function 03)

Note: A differentiation is made between two types of transmissions:
^ Transmission with hydraulic regulation -E17- on which the transmission input speed sensor (inductive sensor) is secured to the underside of the valve body.
^ Transmission with hydraulic regulation - E18I2-J on which the transmission input speed sensor (camshaft position sensory is secured behind valve body at transmission housing.

For information on which transmission is installed, refer to Transmission and Drivetrain; Automatic Transmission; Application and ID:
^ Output Diagnostic Test Mode (DTM) for transmission with hydraulic regulation E17.
^ Output Diagnostic Test Mode (DTM) for transmission with hydraulic regulation E18/2.

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

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 valves 1-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 (clickings of the actuators is very quiet.
^ The solenoid valves 4 -N91-, 5 -N92-, 6 -N93- and 7 -N94- 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.

Notes:
^ When performing the Output Diagnostic Test Mode the individual actuators will be activated until the (arrow) 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.





Activation sequence

Test sequence
^ Connect VAS 5051 tester or VAG 1551 scan tool and enter address word 02 for "Control module for Transmission electronics".
^ Ignition must be switched off during this process.





Indicated on display:
^ Press keys O and 3. (03 selects the function "Output Diagnostic Test Mode").





Indicated on display
^ Confirm entry with key Q.





Indicated on display
^ Valve is activated (clicks), to switch to the next actuator press (arrow) key.
^ If the valve does not click, perform electrical check.
Malfunction is stored in DTC memory, DTC table.

Eventually electrical malfunctions will be stored in DTC memory of the On Board Diagnostic (OBD), DTC table.





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 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 - 196.
^ For checking function of the kick- down switch -F8-.
- Press (arrow) key to switch to the next actuator.





Indicated on display
^ Solenoid valves activated in position "P" are activated (click), press (arrow) key to switch to the next actuator.
^ Can be disregarded.
^ Press (arrow) key.





Indicated on display
^ Press (arrow) key





Indicated on display
^ Pressing the (arrow) key will terminate the Output Diagnostic Test Mode.





Indicated on display:
^ To repeat the Output Diagnostic Test Mode the ignition must be switched off and then on again, then again select the function 03 Output Diagnostic Test Mode.

Output Diagnostic Test Mode (DTM)(scan tool function 03), transmissions with hydraulic regulation -E1 8/2-

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 valves 1 -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 valves 1 -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 offend on again.
