The retained accessory power (RAP) feature allows you to
operate the following components after the ignition switch is turned from
the RUN position to the LOCK or the OFF position:
• | The driver information center (If Equipped) |
These circuits are powered through the RAP relay terminal 30
in relay block 2. The RAP relay terminal 85 and terminal 87
are powered at all times from the RAP fuse in the underhood fuse block through
CKT 742 (RED). The ground is controlled by the body control module
(BCM) through CKT 755 (BLK). Power is also supplied to terminal 87A
of the RAP relay from the ignition switch. With the ignition switch in the
ACC or RUN position, the RAP relay is powered through CKT 3 (BRN).
With the RAP relay de-energized, power is supplied to the accessories from
the ignition switch. The RAP relay is energized when a ground is provided
by the BCM. The BCM will energize the RAP relay when the ignition switch
is turned to the OFF position and all of the doors are closed. This closes
the contacts at terminal 87 and terminal 30 of the RAP relay
in order to power the accessories. The accessories will remain operational
until the ground is removed from the relay. The BCM will remove the ground
when one of the following conditions occur:
• | A 20 minute timer has elapsed. |
• | The driver/passenger door is opened. |
• | The ignition switch is activated. |
• | The liftgate jamb switch is activated. |
