Transmission Park Selector Switch -F305-, REMOVING AND INSTALLING: Notes

Transmission Park Selector Switch -F305- consists of two micro-switches. The two micro-switches create the signal that the electronic ignition key removal lock needs to release the key only in selector lever position P.

The first micro-switch is closed when the shift lock solenoid -N110- is not active when the selector lever is in "P" (brake pedal not pressed) and also the selector lever manual release below the ashtray is not actuated.

The second micro-switch is closed when the button on selector lever handle is not actuated in selector lever position "P".

Following points must be observed before replacing Transmission Park Selector Switch -F305- :

1. Both micro-switches are switched electrically in sequence, that is, both switches must be closed for ignition key to be removed. Micro-switches can be checked using Vehicle Diagnosis, Testing and Information SystemVAS 5051A in Guided Fault Finding. After performing tests on vehicle system, you must select test program "F305 - Gear selector position P switch" via function/component selection (drive/automatic transmission/01-On Board Diagnostic (OBD) capable systems/02 - Transmission Electronics/Electrical components).
2. An electrical test on the micro-switch is also possible. If a continuity test is performed with a multimeter, note that in this case, there is a resistance value of approximately 470 Ohm when both switches are closed.
