What is the easiest way to bypass the security light on my 98 bravada


The security 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. Remember too, the TDM controls the security light. Sometimes you can have ALL the symptoms and no lights.

1998 oldsmobile bravada security light flashing car wont start


This happens due to a failed or failing antitheft system. When the system cant communicate properly, it will disable your starter or injectors and show the SECURITY light. Go to this link for info and ways to beat this system yourself.

What does itmean when the security light come on?


the light usually comes on when you turn on your key, BUT if the security light is flashing and the car wont start, it can be reset by turning on the key till all the lights come on and let it set for 10 minutes and after that turn the key off for 3 seconds and then it should start. hope this helps.
