Seville STS V8-4.6L VIN 9 (1998)
Accessory Delay Module: Initial Inspection and Diagnostic Overview
Circuit Description
The Dash Integration Module (DIM) determines the ignition switch status (OFF, RUN, etc.) by monitoring connector C1 terminals A1, A2, A3, B1 and
B2.
When the DIM determines that the ignition switch has been turned to OFF it sends a class 2 serial data message to the radio, LH front door module
(LFDM), Rear Integration Module (RIM) and cellular telephone module (if equipped) to enable RAP. After approximately 10 minutes the DIM sends
another class 2 serial data massage to disable RAP.
The DIM receives door status (OPEN, CLOSED, etc.) from the LFDM by a class 2 serial data line message. When the DIM determines that a passenger
compartment door has been opened it sends out a class 2 serial data message to disable RAP, regardless of the elapsed time.
Circuit Operation
Retained Accessory Power (RAP) is a standard feature. RAP allows the radio power windows, and it equipped, sunroof and cellular telephone to operate
for approximately 10 minutes after the ignition switch has been turned to OFF, or until a passenger compartment door is opened.
