Question about Cars & Trucks

1 Answer

Hi I have a 2002 Chevy s10 that is having a malfunction with electrical system and I'm not sure where to start. When car is in drive the locks... Lock. But now while in driving they often open or reclose for no reason. Also the car alarm always goes off during the night..1230 or later sometimes once sometimes multiple times. Is it poltergeist? Wondering if there is a fuse I can pull to disconnect the dang alarm. TY

Sounds like a problem with a door sensor or the body control module. The body computer takes signals from the doors and activates the horn in the case of theft. It also powers the door locks.
You may be able to pull the fuse for the bcm but that could cause more problems when you go to start the truck.

    Interesting. I was thinking of pulling the fuse at night so I don't wake myself or the neighbors up... It has been every night for a week.
    Also, I don't think there was a BCM Fuse but I will check tomorrow, thats a great tip!
    Also I had new pins put into the door a couple of years ago bc the door panel was acting up bc the door was broken... After some more time the door panel itself broke So i removed rhe panel... everything else is now duct taped... It's been like that for a year now. Probably is a loose wire. Thanks for your help!

SOURCE: VW Jetta 2003 1.9 TDI trunk does not want to open with remote

If your lock actuator engages (you can hear the sound it makes) with the remote/electric button on the door, but the trunk doesn't open then the problem is likely a broken plastic arm that the electric assembly pushes. You can see it if you unscrew the inside cover from the trunk lid and try the remote. I started having the same issue with VW Jetta 2002 GLS that was rear-ended 8 months ago. My guess is the cracked plastic finally gave out in the cold weather.

SOURCE: After alarm goes off, all electrical works except car won't start

hi there
from what it sounds to me is that the alarm is still in anit theft mode
i had this happen to my vehicle

one thing you can try is lock all the doors try and unlock from the passenger side make sure that all the lock come up to the top where they should be
then try it

if that does not work then lift up the rear of the car like it was being towed and it should reset the alarm
short of that you will have to have alarm shop come to you

SOURCE: Explorer alarm going off randomly; additional electrical isues

Open drivers door and look at the hinge area. You will see a black rubber accordion looking tube going from the door to the a-pillar. This is the protector for the wiring harness. Wiggle it and see if this recreates your concern. If it does then pop it loose at both ends so you can inspect the wiring.Check each one carefully,feel them and tug on them.You will be looking for one that the wire inside the wiring insulation has broken,the two wires to really look at closley are the YE/BK and BK .
It may also possibly be a door ajar switch sticking and for this take some WD40 and shoot some in each latch on the side of the door and open and close the door several times and this usually un-sticks it.

SOURCE: 1993 Nissan Maxima SE Car Alarm freaks out, and other electrical

Im no professional but i did recently buy a 93 maxima and i have the same security alarm problem and my powered locks dont work at all. im taking off the door panel today to take a look and see if the alarm sensor is loose or damaged, if it is, ill probably just disconnect it. one thing i have noticed though is that when i hit the lock or unlock button, i hear a faint click from the dashboard area which im assuming is the solenoid on a transistor which would mean that the buttons work but the transistor isnt delivering power. Semi-Solution for Locks: Listen for very quiet click when you lock/unlock doors, if you hear it, uve got major work to do, if you dont, then take apart the door and check the switch connections. Semi-Solution for Alarm: take off the door panel and disconnect the sensor.

2000 chevy s10 wont keep running many scan codes


Your truck has an antitheft system called passlock. It runs thru you bcm. When this system fails, your truck will start for 1-5 seconds and then stall. The fuel enable is switched off, and injectors fail to squirt. This may be your problem and is a "bypassable" problem. This link explains.

Keyless entry wont work 2002 chevy s10


The only way to program them is with a scan tool so you'll need to visit your local dealer to have it done. Here is how it is done.

  1. Install a scan tool.
  2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
  3. Press the START soft key on the scan tool. Important: The scan tool must stay connected until all of the transmitters are programmed.
  4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
  5. Repeat the previous step in order to program up to 4 transmitters.
  6. Remove the scan tool.
  7. Operate the transmitter functions in order to verify correct system operation.
