Serial Data Controlled RAP

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

RAP systems controlled by serial data are as follows:

Windows 

Window RAP activation/termination timing is the same as relay operation. The front window switches are separate modules that operate the windows on their respective side of the vehicle

Radio 

Radio RAP activation/termination is the same as relay operation with 1 exception; the only door switch that will turn off the radio during RAP is the driver door open switch.

Vehicle Communication Interface Module (VCIM) (Onstar®) 

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.
