Question about Chevrolet Silverado 1500

1 Answer

Have a 1999 Silvrado. Has the factory alarm/security sytem. Fobs quit working years ago so havn't used it. Starting a couple of days ago it would just start going off. Cycle the door locks or ignition key and will shut off. Sometimes followed 5 or 6 horn beeps and it starts blaring again. Help me with my gremlins. Thanks Paul

    Hello Ditech. I am waiting for my load tester to arrive from Harbor Frieght. I charged the battery for several hours last weekend after reading your comment. It seems to help. Thank you.

The first thing I would do would be to give the battery a good load test. I have seen low or partially shorted batteries cause all kinds of problems with engine computers, body control computers and security modules. Many times, the customer states that the vehicle seems to start and run ok. When I load test the battery I find that it is only at 40% of its rated capacity. Computers do all kinds of wierd things when they get hungry :)

Factory alarm for 2001 cabrio, is it part of the radio?

No, it is not part of the radio unit proper. I have been driving my car since it was 3 days old without the factory radio. I could not tell you where the alarm is located, & I would not cut any of the original wires that lead to the radio to the harness, those might have something to do with the alarm, Vw tends to wire things funny

Let me be a little more specific about the steering column security system, I was stranded for half a day two years ago. The car would start for half a second and die. When I finally got it to the d

1999 GMC Safari is equipped with a PassLock* system. It is designed to disable engine starting unless the ignition lock cylinder rotates correctly when the proper key is installed. The system is similar in concept to the PassKey* system. However, it eliminates the need for a key-mounted resistor pellet.
The components of the PassLock* system are as follows:
> The ignition lock cylinder
> The ignition switch
> The PassLock* sensor
> The PassLock* module
> The security indicator
> The Vehicle Control Module (VCM)

If any of the components (with the exception of the security indicator) is replaced, the PassLock* sytem must be reprogramed before engine start will be enabled.

When the system malfunctions, it is necessary to retrieve fault codes from the VCM to correctly determine which part of the system is causing the problem.

I have a 1999 jeep grand cherokee. the alarm goes off whenever i open the door if the vehicle has been locked the alarm stops when i start the vehicle i only have a key, no remote any ideas on how to fix...

If ithe alarm is factory when they will have to reset the alarm module with a scanner. If the alarm if aftermarket go to the control module and see if it has a reset button. FOBs (remote) can reset alarm. You Jeep is always set for break-in mode. The FOB sets this when ever the FOB is used to lock the doors. May be bad alarm module - Sorry - Good luck

I have a 94 Jeep Grand Cherokee Laredo and the alarm/security system is sparately being set off. I no longer have the "clicker" to reset the sytem. I usually have to end up having to have the car jumped. I...

I had the same problem with my '94 laredo just a few days ago. Seems this is a serious problem with jeeps. Here's how to fix it yourself. First, find the kick panel on the drivers side near the hood release latch. Remove the panel(2 screws). You will see a couple of bundles of wires...I know...I can do this...I did. Look for a purple wire with a yellow stripe. You will see other purple wires, but it HAS to be the one with the yellow stripe. It should be leading into a black connection. Trust me it's there. Once you've found the purple wire with the yellow stripe, the hard part is over. Strip a section of the covering to expose part of the wire. Do not cut wire in half. Then take a piece of similar gauge wire...I used speaker wire pulled in half...and connect one end of it to the exposed part of the purple and yellow wire. Take the other end of the speaker wire, and ground it to the metal part of your jeep with a screw. I ran my wire underneath the plastic trim leading from the kick panel down along floorboard and door opening. there are a couple of screws that hold the trim and carpet to the metal chassie. Wrap end of wire onto end of one of the screws and ground it to metal part of chassie. Adding a small washer will give it a more secure ground. Once you do these steps, your factory alarm will be disabled.
