Serial Data Control of Retained Accessory Power (RAP)
Retained accessory power (RAP) permits the operation of some devices after the
ignition switch is turned OFF. These selected items will remain in operation until
any of the front passenger doors is opened or until the RAP function timer reaches
its shut-off limit, which is 10 minutes. The instrument panel module (IPM)
monitors the ignition mode signal from the ignition mode switch, battery condition
and the front doors status to determine whether RAP should be initiated.
RAP will end when one of the following conditions is met:
| • | The IPM receives information about the opening of the driver or the front
passenger door. |
| • | The battery capacity decreases below a prescribed limit. |
| • | Any other ignition switch state is chosen. |
The functions supported in the RAP power mode are:
| • | The instrument panel cluster (IPC) and driver information center (DIC)
displays |
| • | The entertainment devices |
The sunroof operation is allowed when sunroof enable signal circuit from rear
integration module (RIM) to sunroof module is active. The circuit is activated by
RIM anytime, in all power modes, except Off-Awake. In Off-Awake power mode,
the sunroof enable signal circuit is activated by RIM for the RAP period.
