Where is the RAP Retained Aux Power module/relay located in a 2005 Corvette C6? Where can I find a wiring diagram and how would I check RAP status with a TechII???


Serial Data Control of Retained Accessory Power (RAP)
Retained accessory power (RAP) is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door is opened or until the RAP function timer reaches its shut-off limit.
The class 2 RAP power mode is mapped to GMLAN serial data circuit as Off power mode. Refer to Data Link Communications Description and Operation for more information on data link communications. The body control module (BCM) monitors the ignition mode signal from the ignition mode switch, battery condition and the doors status to determine whether RAP should be initiated. The modules that support the RAP power mode will operate the systems under their control as required by their RAP power mode strategy.
RAP will end when one of the following conditions is met:
• The BCM detects the opening of a passenger compartment door.
• The RAP timer expires.
• The battery capacity decreases below a prescribed limit.
• Any other ignition switch state is chosen.
The functions supported in the RAP power mode are:
• The power windows
• The instrument panel cluster (IPC) and driver information center (DIC) displays
• The entertainment devices

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.

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.

To be more specific its a 91 eldorado. i have the wiring grid for the bcm but can't locate a relay. everything i read suggested control module/resistor but nothing changed with a new one.


please , do post all facts. none of this makes any sense
sorry !
what car, 91 eldo, ok. Caddy. a very old car. (problems aplenty)
what engine?????????? is it an engine issue???????
3.0, 4.5,4.6l or 4.9Liter ? DOHC engine>?

what country> (guess USA, but how would i know that?)
BCM a 91 has a BCM. ill look that up, GRid what is a grid.?
why not post the symptoms and get GREAT advice.?
I see no BCM, (body computer in 1991 only the PCM /ECU)

ok i now read all you post and see the word blower.
the HVAC blower?
some cads have, quote.
A vehicle that has front and rear climate controls may be configured differently than a vehicle that has front controls only.

does the blower fail on all speeds,?
ok, you said, blower runs with the ignition key removed.
this is NOT a blower problem, its a KEY issue.(circuiT)
AH, GRID, you mean a SCHEMTIC, or wiring diagram.
the FSM has this as does alldata.com (should)

sadly my online source the climate control module is not covered.

Id check my ignition key (off) the pins on the switch proper
do not have power on the output pins.
this car has yellow wire that is hot at all times
but the others must be dead key off.
other key facts. no pun

under dash "intererior relay center"
pull the relays 1 by one ,see if the blower goes off, be a big clue.

15 relays there, and 2 spare spots
RAP relay?
RAP Accessories?
Retained Accessory Power
some cars have this , and delays the aCCessories from turning off
until, doors open or even a delay.
what controls this in 1991 ive not a clue.
quotes from web:
The 85 redesign introduced the "retained power accessory" feature where certain features like the radio and power windows remain available for a short period of time after the ignition is shut off.

on new cars this is a BCM function, pure software. too.
cept a relay.
its only my guess that this is RAP failure causing Climate control to fail. pure guess.
no drawings,
id buy the FSM. i never restore any old car without one.
saves me a bundle over time.

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
(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 (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 (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

When I turn the car off,and pull the key out,the radio light comes on and I can play the radio also.if I open the door,it all shuts off.What is wrong?


The feature is called "retained accessory power" or RAP for short. The purpose is to allow accessories such as the radio, power windows and blower functions to continue for the drivers convenience after the key is turned to the off position or the key is removed. The RAP feature will remain active for 20 minutes or until the drivers door is open which ever occurs first.
Hope this explains it for you.

My power window in my 2002 chevy impala will not work


The RAP circuit breaker is directly behind the left side fuse panel. The chevy dealer acts like its a big secret and wants 75.00 to plug it in. You have to reach up under the dash and plug it in the BACK side of the left fuse panel. The diagram on the plastic cover is misleading. If you put the seat all the way back, you will have to lay on your back and with a flashlight you should look and you will see where it plugs in. This is on a 2002 chevy impala. Hope this helps.
