Lift Glass Release Function

The lift glass release switch is an input to the BCM. The BCM will command the lift glass to release if one of the following conditions exists:
^ The vehicle is in PARK/NEUTRAL.
^ The park brake conditions are met.
^ The lift glass release switch is pressed.

When the BCM receives a message to activate the lift glass release solenoid from the RFA module, the BCM energizes the lift glass release relay if one of the following conditions exists:
^ The vehicle is in PARK/NEUTRAL.
^ The park brake conditions are met.
