Retained Accessory Power (Rap): Enabling

When the ignition switch is turned to RUN position, the BCM grounds the coils of the RAP relays through CKT 707 at terminal 2A10 and both relays energize. See WIRING DIAGRAMS  . After the ignition is turned off, the BCM starts an internal ten minute timer while keeping the RAP relays energized.

Battery voltage is applied at all times through Fuse D9, Maxi(R) Fuse 2 and respective CKTs 440 and 1446 to the coils/contacts of RAP ACC Relay "A" and RAP Ignition 3 Relay. When the RAP relays are energized battery voltage is applied through the contacts of RAP ACC Relay "A" CKT 4, Fuses A1 and A3 and CKTs 93 and 41 to the Wiper/Washer Switch, the Radio Control Head and the Remote Radio Receiver. The radio and wiper system can now operate.

Battery voltage is also applied through the contacts of RAP Ignition 3 Relay, CKT 70, RAP Circuit Breaker and CKT 76 to the power window/trunk lid release systems and the Console Compartment Lamp. The RAP circuits can be tested by entering diagnostics and selecting BCM Output BO03. When the output is LO the RAP relays should energize, and when the output is HI the RAP relays should de-energize.
