Question about Chevrolet Cavalier

1 Answer

Have a 98 Z-24, the theft system lamp will not shut off. The car starts and stays running. Is there a way to shut the light off or bypass the theft system to avoid having the light come back on. I bought it used and have no original key... the keys I have will now also come out of ignition while the car is running.

2005 avalanche Fog lights are staying on with


The fog lamps are computer controlled .the body control module (BCM) will energize the fog lamp relay control circuit. The BCM receives the park lamp ON signal from the interior park lamps supply voltage signal circuit.
DTC B2527 Front Fog Lamps Circuit Low
The body control module (BCM) monitors the front fog lamp switch signal circuit in order to determine when the fog lamp relay is to be energized. When the BCM senses that the front fog lamp switch signal circuit is grounded momentarily by pressing the fog lamp switch, the BCM energizes the fog lamp relay by grounding the fog lamp relay control circuit.

Your best bet , take it to the dealer . Could need BCM replaced , would need to do testing using the Tech 2 scan tool . A new BCM has to be programmed .

Body Control Module (BCM) Replacement
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
Important: This procedure has to be performed only for vehicles equipped with the Passlock™ System.
Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically, but the powertrain control module (PCM) must still learn the theft information from the BCM.

Theft system 99 sunfire


The security, antitheft, or passlock light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle.
This link may help you find ways to bypass this or fix it yourself.

Doing the 3 10 minute cycle for the anti theft, and now i hear a long clicking noise. the car still wont start. previously, it stayed on for a couple of seconds.help


Car starts up then shuts off. Theft light comes on. Took it to the dealer to diagnose. Result was bad "pass lock sensor". Dealer wanted $300 for the part and with labor they wanted to charge $615. yea right. Found online that this system can be bypassed with keyless entry module. www.gmpasslock.com. Ordered part #PLJX for $79 and had it installed at Alarms etc. in tampa florida on nebraska ave for $75. Their number is 813-971-5950. Ops ck good

I have a 1999 sunfire gt and it starts runs for a second and dies,my anti theft light on my dash is not blinking it just stays on,does anybody know a way to bypass the anti theft so that my car will r


Yes, unfortunately this is very common on GM vehicles. Go to this link for everything you need. Rule of thumb is this. If the light is flashing, the problem will be In the ignition or the smart transponder key. If the light is solid, the problem is in the TDM (theft deterrent module). This is the main computer for the theft system. There is a full bypass method on this link listed under PERMANENT FIX. This is what you will need. It will bypass every aspect of the system 100%.

No fire to fuel pump key faul light stay on


If the key fault light is on, it is most likely the anti theft security shutting off your fuel to the injectors. If this is the case, you can bypass this system to get around that anti theft. http://vatspasslockpasskeysecurityhelp.yolasite.com/

1998 suburban wont stay running. Will start and run for one second or two then dies. This will continue over and over. If it will get past the two second time will stay running til shut off. Is this fuel...


Starting for a second or two is quite possible that the passlock system is causing it. I've seen this happen before. There are a lot of videos on youtube about bypassing this system. Have a look. bypass GM anti theft YouTube

My dodge carvan won't start after 3 attempts. it will run and then die. the alarm system will then light up. does someone have a quick fix


Put key in ignition (do not start) for EXACTLY 10 minutes. As SOON as the anti-theft lights shuts off, IMMEDIATELY start van.

This is a very common problem in GM vehicles.

There is a Passlock or Passlock2 anti-theft system. You can buy a bypass kit with instructions for it.
