TCM
NOTES:- Output Diagnostic Test Mode can only be performed if the selector lever is in position "P', the engine is not running and the car is stationary
- Output Diagnostic Test Mode is terminated if the engine is started.
- The operation of the Solenoid Valves 1 -N88-, 2 -N89- and 3 -N90- and the shift lock solenoid are checked audibly during Output Diagnostic Test Mode. Avoid background noises when performing the audible check as the switching noise (clicking) of the final control elements is very quiet.
- The Solenoid Valves 4 -N91-, 5 -N92-, 6 -N93- and 7 -N94- are actuated by the Output Diagnostic Test Mode. It is not possible to perform a direct operational check of these components although any electrical malfunctions which occur during this actuation are stored by the On Board Diagnostic (OBD) in the Diagnostic Trouble Code (DTC) memory
- During Output Diagnostic Test Mode the individual control elements continue to be actuated until the key is pressed.
- After switching on the ignition, only a complete Output Diagnostic Test Mode is possible. To repeat Output Diagnostic Test Mode, the ignition must be switched off again and on.

Kickdown switch -F8-
NOTES:
- What is actuated is not the Kick Down Switch -F8- but the switch off function of the A/C in the Transmission Control Module -J217-.
- If the kick down switch is operated, the transmission control module switches The output to the A/C to Ground. This causes the A/C compressor to be switched off for a short time.
- Signal can be tested in Measuring Value Block 11
- Testing operation of the Kick Down Switch -F8-.
