KICKDOWN SWITCH ____________________________________________ (range ON/OFF) Indicates the state of the kickdown switch. The kickdown switch is integrated into the Bowden accelerator cable. It is used to detect situations where the accelerator pedal is depressed beyond the full-throttle point. With the kickdown switch actuated, the AC compressor is disengaged to provide more power on acceleration. NOTE: i On vehicles with a TDI engine, the TCM receives the kickdown signal from the acceleration pedal position (APP) sensor.
