How the Parking button works:
When pressed, the button sends a signal to the automatic transmission control unit, which activates the mechanism that locks the gearbox output shaft. This prevents vehicle movement even on slopes. To exit park mode, press the brake pedal and move the selector to another position (R, N, D).
Common failures and wear signs:
- Difficulty pressing or sticking of the button.
- Failure to lock in "P" mode.
- Appearance of transmission control system errors.
- Physical damage to the housing (cracks, chips).
Replacement is recommended if any of these symptoms appear to avoid safety risks and further damage to the transmission selector.
Installation:
Installation is performed after removing the decorative trim of the transmission selector. The button is secured in its mounting location and connected to the factory connector. For proper operation, system adaptation using diagnostic equipment may be required.
Using the PPB7 button guarantees full compliance with factory safety and reliability standards.
