Bonneville V6-3.8L VIN K (1996)
Accessory Delay Module: Initial Inspection and Diagnostic Overview
Circuit Operation
Retained Accessory Power
(RAP) allows the radio, power windows and sunroof to be operated for approximately 10 minutes after turning the ignition
switch to "OFF."
Battery voltage is applied at all times from RH I/P Power Distribution Center Fuse 2 to the Remote Function Actuator
(RFA) Module, and from Engine
Compartment MaxiFuse(R) Block RH "IGN1." When the ignition switch is turned to "ACCY" or "RUN," voltage is applied from I/P Fuse Block
WPR/WSHR Fuse 8E to the Remote Function Actuator (RFA) Module "IGNITION 2" input.
When the ignition switch is turned to "OFF," the RFA module senses this and energizes the RAP Relay by grounding RAP Relay terminal F86. With the
RAP relay energized, battery voltage from Engine Compartment MaxiFuse(R) Block RH "IGN1" is applied to power the radio. The radio operates for
approximately
10 minutes or until any door is opened. If any door is opened, the RFA module deenergizes the RAP Relay by removing the ground
source from RAP Relay terminal F86, thus discontinuing power to the radio. The
10 minute time interval can be reset by turning the ignition switch to
"RUN," then back to "OFF."
System Diagnosis

Begin System Diagnosis by following
Chart #1 Retained Accessory Power (RAP) inoperative. See: Symptom Related Diagnostic Procedures
Troubleshooting Hints
1. Check RH I/P Power Distribution Center Fuse 2 by visual inspection.
2. Check I/P Fuse Block WPR/WSHR Fuse 8E by visual inspection.
3. Check Engine Compartment MaxiFuse(R) Block RH "IGN1" Fuse by visual inspection.
^
Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a
continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be
checked by monitoring for a voltage drop with the system operational (under load).
^
Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
