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 shut-off limit.
The BCM turns OFF the RAP function and de-energizes the RAP#1 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 20 minutes. |
• | The transition from OFF to RUN/ON of the ignition switch. |
RAP Relay #1
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#1 relay. This provides power for
the following:
• | RAP Relay #2 Control Signal |
• | Rear Seat Audio Controller |
• | Left and Right Steering Wheel Control Switches. |
• | Left Front and Rear Power Window Control Switches |
• | Left Front and Rear Power door lock Switches |
RAP Relay #2
When the BCM commands the RAP function active, RAP#1 relay supplies a signal
to RAP#2 relay's control circuit. RAP#2 relay then supplies an isolated fused power
source to the following accessories:
• | Right Front and Rear Power Window Control Switches |
• | Right Front and Rear Power door lock Switches |
