Question about 2007 Hummer H3 SUV

1 Answer

The power locks go up and down at random times along with the door chime when driving our H3, can this be reset or will I need a new BCM?

So far i have called the dealership who basically says to bring it in and have it checked, followed by the standard answer that it will cost $500-$700 to repair.

Dealer is trying to soak you. You have a short in the power lock circuit. It could be as simple as a loose wire in the door(s). If you have a voltmeter, you can check each lock switch individually, if you find one that's bad, replace it. drive H3 for a while, see if you solved the problem. if not try another one. U-tube has a video on the subject, contact local repair shop for another price estimate.
My dealer told me headlight switch repair would be $ 500, local repair did the work for $ 88 including parts.

How to program New key switch 2000 oldsmobile silhouette


Key switch ? key fob ? Transmitter Programming ?
If you lose a transmitter, program the old and new transmitter(s) into the remote control door lock receiver's memory. Up to 4 transmitters may be programmed.
Important: Once the remote control door lock receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information, requiring the programming of all transmitters.
Program only 1 vehicle remote control door lock receiver at a time. If more than 1 receiver is being programmed at the same time, it is possible that the same transmitter could be programmed to more than 1 remote control door lock receiver.
Perform the following steps in order to program the transmitter:
  1. Remove the ignition key from the ignition lock cylinder.
  2. Remove the BCM PRGRM fuse from the fuse panel. Refer to Fuse Block in Wiring Systems.
  3. Close all of the doors.
  4. Close the lift gate.
  5. Turn the ignition lock cylinder to ACC.
  6. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
  7. Open and close any vehicle door.
  8. A chime will be heard when the system enters the BCM programming/diagnostic mode.
    Important: After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary to wait approximately 14 seconds for a second chime that will confirm successful programming.
  9. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
  10. Repeat the previous step on each additional transmitter to be programmed.
  11. Remove the ignition key from the ignition lock cylinder.
  12. Install the BCM PRGRM fuse back into the fuse panel. Refer to Fuse Block in Wiring Systems.

If I lock my 2006 Chevy Cobalt, the security system will randomly lock and unlock the doors accompanied with the horn honking


I think you have a BCM - body control module problem ! The BCM controls the automatic door locks .
Automatic Door Lock Operation
This BCM controlled feature can be personalized to driver preference. Refer to Power Door Systems Connector End Views Personalization Description and Operation in Personalization.
The BCM will automatically lock the vehicle doors if the following conditions exist:
?€¢
All vehicles doors are closed.


?€¢
The ignition is in the ON position.


?€¢
The vehicle is shifted out of PARK.

The BCM will then unlock the doors when the ignition is placed in the OFF position. Do the exterior lights flash as well as the horn sounding ?
Body Control Module (BCM)
The
Content Theft Deterrent
system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.
When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.

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

How do I program keyless entry on my 2002 grand prix? I have tried the way I found by removing mall pgm fuse n open door n turn key to acc. Doesnt work. The fob I have was for gp why it not work?


Important: All transmitters which are to be recognized by the remote control door lock transmitter (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to four transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
  1. Remove the ignition key from the ignition lock cylinder.
  2. Close all of the doors.
  3. Remove the MALL PGM fuse from the fuse block.
  4. Insert the ignition key into the ignition lock cylinder.
  5. Turn the ignition to ACC.
  6. The body control module (BCM) will perform the following in order to identify the type of BCM installed in the vehicle:
    ?€¢
    Flash the seat belt indicator 1, 2, or 3 times.


    ?€¢
    Chime 1, 2, or 3 times.

  7. Turn the ignition to OFF, and then back to ACC within 1 second.
  8. The BCM may begin to chime and flash diagnostic trouble codes (DTCs). If the BCM has stored any DTCs, refer to Diagnostic System Check - Body Control System in Body Control System.
  9. Open and then close any vehicle door.
  10. The BCM will chime in order to confirm that the programming mode has been entered.
  11. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for approximately 14 seconds.
  12. Important: After approximately 7 seconds the BCM will chime once to confirm that synchronization has been completed. After approximately 14 seconds the BCM will chime a second time to confirm that the programming has been completed.
  13. Repeat the previous step in order to program each additional transmitter.
  14. Remove the ignition key from the ignition lock cylinder.
  15. Install the MALL PGM fuse into the fuse block.
  16. Operate the functions of each transmitter in order to verify correct system operation.

Does the bcm control the alarm in a 2006 monte Carlo? I can't seem to get the alarm to go off. I've also noticed that I have no chime and turn signal sounds. I just recently purchased this car and...


The no chime and turn signal has nothing to do with the alarm. You have a issue with power supply to turn flasher and door chime. The alarm consist of The door ajar switch,body control module,front door lock switch,power door lock switch. You need to check your fuse for turn signal and the door chime

My instrument lights and the high beam indicator doesn't work. I checked all the fuses and they are good.What else do I need to check?


It sounds like the Body Control Module (BCM) took a dump. They're about $50.00 at a junk yard, $500.00 for a rebuilt one from a dealer. It's located behind the fuse panel under the dashboard.

If you get a used one, make certain that the part numbers match.

Good luck! The BCM provides the following features:
• Automatic door locks
• Battery protection
• Chimes
• Compass/mini-trip support
• Courtesy lamps
• BCM diagnostic support
• Door lock inhibit
• Headlamp time delay
• Ignition key lamp
• Illuminated entry
• Instrument panel dimming
• Mechanical instrument cluster support
• Power door locks (with/without remote keyless entry)
• Sliding door memory lock
• Vehicle Theft Security system (VTSS)
• Windshield wipers / washers (front and rear)

Flashing light on my dashboard for air conditioner and blower


Possible Solution 1 - Check your fuses2 - You can try disconnecting the battery for about 5 minutes to reset the onboard computer (Body Control Module BCM) which controls the items you mention. 3 - If that does not work, you can then try disconnecting (with battery disconnected for at least 30 mins to disarm airbag) and reattaching the wire connector to the BCM in case it has developed a bad connection - This is located under the dashboard on the drivers side. Should be a big square or rectangle connector with lots of wires and a bolt going through it. Unscrew the bolt and disconnect the connector from the BCM then reattach and screw the bolt back in.
The Body Control Module (BCM) supplies vehicle occupants with visual and audible information and controls various vehicle functions, To provide and receive information, the module is interfaced to the vehicle's serial bus communications network, the Chrysler Collision Detection (CCD) bus. This network consists of the powertrain control module (PCM), the Transmission Control Module (TCM) , the electro/mechanical instrument cluster (MIC) , the Airbag Control Module (ACM) , the Compass/mini-trip module and the Controller Antilock brake Module (CAB). The BCM is operational when battery power is supplied to the module. Ignition switch power is needed for ignition switch functions.
The BCM provides the following features: • Automatic door locks • Battery protection • Chimes • Compass/mini-trip support • Courtesy lamps • BCM diagnostic support • Door lock inhibit • Headlamp time delay • Ignition key lamp • Illuminated entry • Instrument panel dimming • Mechanical instrument cluster support • Power door locks (with/without remote keyless entry) • Sliding door memory lock • Vehicle Theft Security system (VTSS) • Windshield wipers / washers (front and rear)
