2006 chevy impala radio & dash lights stay on now when ahut car off, key out and close and lock doors automatically. Never happened before. Help please..


Could be relay contact's stuck closed allowing power to stay on . Or it could be a BCM - body control module problem .

Retained Accessory Power (RAP)
The retained accessory power (RAP) system allows certain vehicle functions to operate for a specific amount of time after the ignition switch is turned OFF. The body control module (BCM) monitors the ignition switch position, battery condition, and each door ajar switch status to determine whether RAP should be initiated or terminated. RAP is controlled with two different methods; serial data and relay control. Some modules receive a RAP message from the BCM over the serial data circuits. Serial data controlled RAP is deactivated as required by their modules RAP power mode operation. Other subsystems are activated directly by the BCM through a RAP relay. Components and systems that are active in RAP are also activated anytime the ignition is any position other than OFF regardless of the door switch signals.

Relay Controlled RAP
The BCM keeps the RAP relay energized during all power modes, except Off-Awake and Crank. The relay is also energized for approximately 10 minutes after shutting the ignition OFF and removing the key, providing no door is opened.
Relay controlled RAP will end when one of the following conditions is met:
• The BCM receives an input from any door ajar or open switch indicating the opening of any door after the ignition key is out of the ignition.
Important: If the BCM is receiving any door ajar or open signal from those switches when the ignition key is turned OFF, RAP will not initiate.
• The BCM internal timer for the RAP expires after approximately 10 minutes.
• The BCM detects a decrease in battery capacity below a prescribed limit.
Systems powered by the RAP relay during the RAP power mode are as follows:
• A/T shift lock control solenoid assembly (w/ floor shifter)
• Power window circuit breaker
• RAP fuse
• Inside rearview mirror (DD6)
• Sunroof (CF5)
Serial Data Controlled RAP
RAP systems controlled by serial data are as follows:
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.

Do you know what a DTC - diagnostic trouble code is ?
DTC B1475 00: Retained Accessory Power Circuit

Your best bet , take it to a Chevy dealer !

I have a 2000 Suburban and my rap 1 fuse is missing what does it control


1500?/ you forgot that.?
some folks hate RAP, many. no,not the so called music.
first the meaning
R.A.P.
Retained Accessory Power

depends on car ./year etc.
but to find out all it does, login to alldata.com and read the schematic.
what it does is keep the car in accessory poweredup for up to 10mins.
key off.
if you live say in Alaska that can suck, using power key off.
draining the battery for funs and giggles can kill you, if not lucky.

1500
the rap fuse pulled
kills the RAP Relay
that means the BCM can never ever close that relay./

this kills the RAP RADIO feature (read the operators guide yet, it explains this)

the Radio schematic shows there are 2 power pins
RAP C1p9
and
RADIO.C1p10 orange.

so that kills rap power to the radio, there are others.
but that all depends on audio and accessories with RAP options.
the FSM Cover all this, no need to guess.
as does alldata.com, all the time.

Problems WithChevy TrailBlazers
ElectricalProblems
Some of the mostcommon problems with the TrailBlazer involve the vehicle's electrical systemand accessories. Many drivers have experienced problems with the dashboardgauges, including the fuel gauge, speedometer and "check engine"warning light. Additional electrical problems include power automatic doorlocks and windows that fail to work or operate intermittently. These problemscan be difficult to diagnose as they can result from anything from a faultybattery to problems with the wiring or other electrical components.
Read more: Problems With Chevy TrailBlazers ' eHow.com A fuse contains a thin metal bridge between two terminals. When too muchelectrical current is drawn through the fuse the bridge melts, breaking thecircuit. This feature prevents damage to electrical components and limits thepossibility of a fire.The Chevrolet Blazer utilizes small fuses to protect thevehicle's wiring harness from overload. These are typically plug-in blades, notthe glass-barrel fuses used in older vehicles.
Location The fuse panel ona Chevy Blazer is located on the driver's side of the firewall beneath thedashboard. Some later models may be equipped with a fuse panel cover. To removethe cover, pull the retaining clips loose on each side and lift the cover fromthe panel. Replacing a Fuse Locatethe fuse you believe is burned out by its label or use the owner's manual as aguide. To remove the fuse, you may need needle-nose pliers; don't put too muchpressure on the fuse or you could crack the casing. Examine the thin metalstrip between the two terminals. If it is broken, scorched or deformed, it mustbe replaced. Read more: Fuse Box Instructions for a Chevy Blazer ' eHow.com

Sunroof will not work


Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

The RAP relay is responsible for the radio and windows working after the igntion is turned off.

The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

(1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay(1) Park Lamp Relay
(2) Courtesy Lamp Relay
(3) Retained Accessory Power (RAP) Relay
(4) Power Seats Circuit Breaker

(7) Door Lock Relay
(8) Headlamp Ground Relay

Power outlets not working on 2008 Chevy Equinox


Replace the Aux Pwr fuse. On the 2008 Equinox, this fuse is in the fuse block under the hood. It is fuse number 3, 20A (yellow), located on the left side as you're looking it, in the slot immediately forward of the fuse puller tool. Way too late for Kevin256, but I just did this on my daughter's '08 Equinox and it fixed the problem.
