Shift Interlock: Description and Operation






DESCRIPTION





The Shifter's serpentine pattern does not require the shifter to have a button on the knob to release it from "Park". There is a blocking lever within the Shifter that prevents undesired shifting out of "Park".










The shifter has a solenoid which is actuated by depressing the brake pedal. This prevents shifting out of "Park" without the brake pedal being depressed. To operate the solenoid, the ignition must be in the "On" or "Run" position and the brake pedal must be depressed. The Brake Switch sends a signal to the Cabin Compartment Node (CCN) and the CCN, in turn, energizes the solenoid that moves the Park Lock Lever to allow the driver to shift out of 'Park". On the right side of the Console Pod is a plug that allows access to the Park Lock Lever for manual operation.
