The body control module (BCM) monitors the ignition switch position, battery condition, and each door ajar/open switch status to determine whether the retained accessory power should be initiated or terminated. Retained accessory power is controlled by two different methods; relay control and serial data. Some modules receive a retained accessory power message from the BCM over the serial data circuits. Serial data controlled retained accessory power is deactivated as required by their modules retained accessory power mode operation. Other subsystems are activated directly by the BCM through a relay. Components and systems that are active in retained accessory power are also activated anytime the ignition is any position other than OFF regardless of the door switch signals.
The BCM keeps the relay energized during all power modes, except Off-Awake and Crank. The relay is also energized for approximately 10 minutes after shutting the ignition OFF and removing the key, providing no door is opened.
Relay controlled retained accessory power will end when one of the following conditions is met:
Note:
If the BCM is receiving any door ajar or open signal from those switches when the ignition key is turned OFF, retained accessory power will not initiate.
Systems powered by the retained accessory power relay during the retained accessory power mode are as follows:
Note:
The vehicle may not be equipped with all components as listed below.
Retained accessory power systems controlled by serial data are as follows:
RadioRadio retained accessory power activation / termination is the same as relay operation with one exception; the only door switch that will turn off the radio during retained accessory power is the driver door open switch.
Vehicle Communication Interface Module (VCIM) (Onstar?®) (If Equipped)VCIM RAP activation/termination is the same as radio operation with 1 exception; if there is an active call when the ignition key is turned off the VCIM will remain in RAP mode, and keep the radio in RAP mode until the call is terminated.

Electronic Ignition System Description
Electronic Ignition System Operation
The electronic ignition system produces and controls the high energy secondary
spark. This spark ignites the compressed air/fuel mixture at precisely the correct
time, providing optimal performance, fuel economy, and control of exhaust emissions.
