General Description
Retained Accessory Power (RAP) is a standard feature. The system allows the radio, wipers power windows, trunk lid and fuel door releases (DeVille/Concours only) and the Astro Roof to be operated after the ignition has been turned off. The system is designed to allow accessory operation for up to ten minutes after the ignition is turned off. The system shuts off all accessories after ten minutes or if a door is opened before ten minutes has elapsed.The main components of the RAP system are the RAP/Illuminated Entry Module (RAPIE), door ajar switches, two RAP Relays and several fuses (see schematic).
When the RAPIE Module sees the ignition has been turned to run, the module performs two operations. First, it terminates illuminated entry and secondly, the module activates the two RAP Relays. The relays allow power to be supplied to the radio, wipers, power windows trunk lid and fuel door releases (DeVille/Concours only) and the Astro Roof. The RAP Relays are wired in parallel with the Ignition Switch. This allows the circuits powered by the RAP Relays to still operate with the ignition in RUN if the RAP system should malfunction.
When the ignition is turned off, the RAPIE Module starts a timer and continues to power the accessory circuits through the RAP Relays. After ten minutes, the RAPIE Module will de-energize the RAP Relays, cutting off power to the accessory circuits. If the RAPIE Module detects a door has been opened through the door ajar switches inputs, the RAPIE Module will de-energize the RAP Relays immediately.
