    This car was flooded and I've been told that BCM (GM # 15234845) is part of the keyless entry (by the way the remote doesn't work) but when I tried to order the part the dealer told me that the part I need is a keyless entry fobs and batterys module (GM # 15835548). So I'm really confused which part is the right one. I wish I could get one of those scanner tools but I don't know which one. What do you recommend? And also, I've been looking for wiring diagrams that show all the electical components . I have the Haynes repair manual but it doesn't show me the keyless module or location of mudules in the car. Thank you for all your help.

The remote control door lock reciever controls the door locks, and tire pressure monitor. If your TPM and remote work normaly then it will not be the RCDLR. The body mudule is involved but I don't see this problem being related to it. About a week ago I had a car like yours with a small short in a door causing this exact issue. You need to get it scaned for body codes to give you a better idea where to go. Let me know if you need moer help. I have looked on the GM service web site and there are no known issues related to this. Good Luck.

    Ok the flooded tells me alot. I can get all those schematics and info for you, but I can not post a link to them. How bad was it flooded? There are two bodys, sedan and extended sedan(malibu max). If you have the regular malibu then the door lock reciever is in the trunk under the back window. If you have the max then it is in a panel beside the rear seat. If the water did not get that deep, I would lean towards the body module. It is in the console on the right side behind a panel. It has a fuse block built into it. I can e-mail you schematics, but I am not supposed to (publish them) . Let me know.

Why doesn't the horn beep when i lock my doors with the remote on my 03 malibu is it a bad relay


When you push the horn switch (button) on the steering wheel ,do the horns work then ? The BCM - body control module energizes the horn relay for keyless entry operation . Start by having BCM checked for DTC'S - diagnostic trouble codes .

How do you reset the alarm system on a 98 olds silhouette after it triggers without the remote entry


Theft Deterrent Arm/Disarm Modes
Important: Although mode 2 provides increased security, the content theft deterrent system disarms only by pressing unlock on the keyless entry transmitter. This can pose a problem if the keyless entry transmitter is damaged, lost, or inoperative for any reason while you attempt to disarm the content theft deterrent system.
Mode 1: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter. The system does not arm when you lock the doors with a power door lock switch.

Mode 2: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the doors with the keyless entry transmitter. The system does not disarm when you unlock the doors with the key.

Mode 3: The system arms when you lock the doors using a power door lock switch or the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter.
Changing the Feature Customization Modes
  1. Turn off the IP dimmer switch.
  2. Turn the ignition switch to the LOCK position.
  3. Remove the BCM PRGRM fuse.
  4. Turn the ignition switch to the ACC position. The BCM flashes the fasten belts indicator and sounds the chime 4 times, which indicates that BCM type 4 is installed on the vehicle. At this point, the BCM has entered the feature customization mode.
  5. In order to change the theft deterrent/shock sensor mode, turn the headlamp switch from OFF to PARK and back to OFF.
  6. The BCM flashes the fasten belts indicator and sounds the chime a number of times equivalent to the theft deterrent/shock sensor mode. A transition past mode 4 repeats the sequence starting with mode 1.
  7. Complete the following steps in order to change the theft deterrent arm/disarm mode:
6.1.
Insert the key in the left front, right front, or liftgate door lock cylinder.


6.2.
Rotate the key from the center to the unlock position.


6.3.
Press the horn button on the remote keyless entry transmitter.


6.4.
Count the number of chimes that you hear. The number of chimes tells you which mode you have set.


6.5.
Press the horn button again in order to change the mode. Continue to press the button until you hear the number of chimes that indicates the mode that you want.


6.6.
Turn the key back to the center position and remove the key from the door key cylinder.

In order to exit and save the current feature customization modes use the following procedure:

  1. Turn the ignition switch to the LOCK position.
  2. Reinstall the BCM PRGRM fuse.
If you are unable to change locking modes Theft Deterrent System Feature Customization Inoperative

Rocker switches,nor remote will lock or unlock doors fuse good


So , the power door locks won't lock or unlock with switches inside the vehicle or with the keyless entry remote fob.??? Is this correct ????
Do you know what a BCM - body control module is ? Do you know what diagnostic trouble codes are ? If not your best bet would be to take your vehicle to a GM dealer or someother qualified repair shop.
DTC B3142 or B3143
The body control module (BCM) provides an output to the driver switch assembly through the door unlock control circuit for controlling automatic door unlock, anti-lockout, and keyless entry unlock functions.
DTC B3152 or B3153
It could be the driver door master switch , could have broken wires inside the rubber boot from the body to the door . Do the power windows work ?
The keyless entry system has the following main components:
• The transmitters
• The body control module (BCM)
When you press a button on a transmitter, the transmitter sends a signal to the BCM. The BCM interprets the signal and activates the requested function.

How did you do this ,,checked and made sure locks and remote programmed,they were,but still do not work ?????

Need a scan tool to program
Important: All key fobs must be programmed each time any one fob is programmed. The scan tool must stay connected until all of the transmitters are programmed.
Install a scan tool and navigate to the BCM Module Setup menu.
Select Program Key Fobs.
Follow the scan tool on-screen directions.
When the programming operations have completed, operate the transmitter functions to verify correct system operation.

Where is BCM located on 2002 PT Cruiser locks working even when car is not on have been told to check BCM don't know where to find it


I don't find a body control module for your car, but according to the wiring diagram the door locks are controlled by a keyless entry module which is located on top of the dash behind the ac vents.
There are three fuses that power the module.
Check with your dealer for more details.

Keyless entry does not unlock doors, open trunk, or start vehicle (remote start built onto keyless entry). Battery is new in BOTH remotes and neither one works. Could a fuse in vehicle be bad? Secondly,...


RFA / MOD fuse 10amp . location - insturment panel fuse box. Fuse Block - I/P
Right side of the I/P, behind the access panel
If the fuse is good your best bet would be to take it to a qualified repair shop , that doesn't mean the dealer . Lot of good independant repair shops around , just have to check the yellow pages.
Do you know what DTC'S are ? diagnostic trouble codes ! Not only the ones for the engine management system OBD 2 . There are also DTC'S for the remote keyless entry system , BCM - body control module. You need a factory or professional scan tool to view this codes
DTC B3101
DTC B3102
DTC B3103
DTC B3106

The remote control door lock receiver (RCDLR) communicates with the body control module (BCM) through the keyless entry serial data circuit. When any button on the keyless entry transmitter is pressed, the transmitter sends a signal to the RCDLR. The RCDLR sends a lock, unlock, or panic alarm request to the BCM, depending on which button is pressed on the transmitter. The BCM receives the message and performs the appropriate function. The BCM also uses the keyless entry serial data circuit in order to communicate with the RCDLR when programming transmitters. Do you know what serial data circuits are ?

DTC B3101 Keyless Entry Data Link Circuit Range/Performance
DTC B3102 Keyless Entry Data Link Circuit Low
DTC B3103 Keyless Entry Data Link Circuit High
DTC B3106 Keyless Entry Data Link Parity Error

This is what the factory manual said as to the location of power steering fluid reservoir ! Not much help , you would do better googling it.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine
