Accessory Delay Module: Description and Operation
RETAINED ACCESSORY POWER (RAP) DESCRIPTION AND OPERATION
SERIAL DATA CONTROL OF RETAINED ACCESSORY POWER (RAP)
Retained accessory power (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
The modules listed below all receive a RAP message from the dash integration module (DIM) over the serial data circuits. The DIM monitors the
ignition switch position, battery condition and passenger compartment door status to determine whether RAP should be initiated. The DIM then sends
a message to the listed modules telling them that they are in RAP power mode. The modules then support the operation of the systems under their
control as required by their RAP power mode strategy.
RAP will end when one of the following conditions are met:
The DIM receives an input as a serial data message from any door module indicating the opening of a passenger compartment door.
The DIM receives a message from its internal timer indicating the end of the RAP period after 10 minutes.
The DIM detects a decrease in battery capacity below a prescribed limit.
The transition from OFF to RUN/ON or ACC of the ignition switch.
The DIM module then sends a serial data message to the listed modules ending the RAP function.
The modules receiving serial data messages for RAP functions are:
The driver door module (DDM)
The front passenger door module (FPDM)
The left rear door module (LRDM)
The rear integration module (RIM)
The right rear door module (RRDM)
The TV antenna module
The vehicle communication Interface module (VCIM)
RELAY CONTROL OF RETAINED ACCESSORY POWER (RAP)
When the rear integration module (RIM) is in the RAP function as described above, it actuates the RAP relay. This provides power during the RAP
period for the sunroof control module w/CF5.
The RIM deactivates the RAP relay to end the RAP function when it ends the RAP function as outlined in the previous text.
