Riviera 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 Rear Fuse Block Fuse "INST PANEL 1" to the Remote Function Actuator
(RFA) Module, and from Rear
Maxi(R) Fuse Block "IGN" Fuse. When the ignition switch is turned to "ACCY" or "RUN," voltage is applied from I/P Fuse Block "WSW" Fuse 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 "B7." With the RAP relay energized, battery voltage from Engine Compartment Maxi® Fuse 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 "B7," 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) INOP. See: Symptom Related Diagnostic Procedures
Troubleshooting Hints
1. Check Rear Fuse Block "INST PANEL 1" Fuse by visual inspection.
2. Check I/P Fuse Block "WSW" Fuse by visual inspection.
3. Check Rear Maxi(R) Fuse Block "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.
