Retained Accessory Power (RAP) Power Mode
RAP is a vehicle power mode that permits the operation of selected customer
convenience items after the ignition switch is turned OFF. These selected items will
remain in operation until a passenger compartment door is opened or until the RAP
function timer reaches its limit.
The BCM turns OFF the RAP function and de-energizes the RAP relay when one of
the following conditions are met:
• | The BCM senses the opening of any door or the liftgate. |
• | The BCM detects a decrease in battery capacity below a prescribed limit. |
• | The BCM receives a message from its internal timer indicating the end
of the RAP period after 10 minutes. |
• | The transition from OFF to RUN/ON on the ignition switch. |
The body control module monitors the ignition switch position, battery condition
and passenger compartment door status to determine whether RAP should be initiated.
If the ignition switch transitions from RUN/ON to OFF, the battery level is within
the acceptable range and the passenger compartment doors are closed, the body control
module energizes the RAP relay. This provides power for the following:
• | power window control switches |
• | power door lock control switches |
• | steering wheel control switches |
• | outside rearview mirror switch |
