© 2018 Madison Ross Media Group. I've had my security light come on a number of times. Well I had the same problem and it turned out that orange tube that has the two wires that read the key resistor were broken so all I did was to read the resistance on the key and then went to radio shack and bought a resistor it was a 2. My car started giving occasional no reads and read okay on reinsert key immediately. I like option 2, bypass by installing a resistor of a correct value.
If you're worried about losing your security feature, you can also place a toggle switch on the wire to disconnect the resistor when needed. And if it is, where in the world would I find another one? Does anyone know what sets this off? I got the placement screws off of it, and when I disconnected the 2 connectors, the seatbelt light quit flashing alltogether. So there's gotta be some kind of connection between all this right? Pulling fuse's till the draw goes away. The easiest fix although it disables this security feature is to measure the resistance in your key the little chip on the part of the key that goes into the ignition using a multi-meter, then buy a resistor from radio shack of the same reistance; then hook the resistor to the two small wires in the orange shroud underneath the dash going into the steering column leaving the wires coming out of the steering column dead. Using the drivers side door unlock it using the key. On 4th attempt, your car should now start.
A very common problem with your vehicle is the wires to the ignition switch that read the chip in the key are prone to breaking after many years of use. The resistance in the thin threads of the wires where the steering column tilts changes while driving, e. I have found the best way to reset the system is to open the hood and lock all of the doors. You may not even notice it. Fully push and release the accelerator pedal 3 times within 5 seconds. This will at least allow you to operate the car. If the wrong resistance is read, the light flashes for 3 minutes, then releases for another try with reading a key resistance again.
Hooking up a amp meter between the neg. Pull the compartment door off. The resistance at the key lock cylinder is not longer read and the resistors supply the correct reading. Normally, that light just stays on instead of flashing when my lap belt isn't fastened. Once in a while it would take 3 minutes. A symptom of impending failure was that the security light would come on while driving which never cuts off the engine--it's only able to do that at starting time and go out. This way, the computer always reads the correct resistance.
At first I did this it fixed the problem but a few months later the problem came back and this time just jiggling the wires didn't help. Always verify all wires, wire colors and diagrams before applying any information found here to your 1998 Buick LeSabre. Do you know which wire needs the resistor and what the ohms should be? I believe there are two small white wires running up the steering column to your key-switch. I don't know if it is supposed to be like that, maybe its telling you they are working I'm not sure I never had the owners manual. Request a Car Alarm Wiring Diagram If you can not find your car alarm wiring, car security wire diagram or auto alarm wire diagram on Modified Life, please feel free to post a car alarm wiring diagram request on this page and we will do our best to find you the diagram, schematic or information you need for your mobile security installation. If it's over 80 miliamps you have a draw on the electrical system.
I usually wait about 10 minutes or so for the light to go … off. It would do the same, show an issue when the car was remote started. Your nearest Autozone will do that for free. It has diagrams and step by step instructions. If it starts and runs normally, the relearn is complete. Resistors are fairly cheap at Radio Shack.
The control units will exchange the correct commands during the next start-up attempt. These day's more like a module not powering down when it's suppose to. The dark blue - is for all other doors and is located low in the drivers kick panel. After the oil has been changed, you'll need to reset your system. I have a 97 Buick Lesabre and have been having a issue with the security light coming on for a few months now. For instance, a failed O2 sensor makes your mixture richer typically which not only burns more fuel but ultimately will ruin your catalytic converter. Good luck and hope this helps, keep me posted.
Measured the resistance and it appears to be in the range of 500-600 ohms. Could anyone let me know if there is anything I can do to turn this security stuff off so I can know that I don't need to take it in if there is something really wrong with my car. The light coming on and going off while driving may indicate the latter is happening. The parking brake also makes this light come on be sure it is fully released, Technical info,,,. A dealership's answer that will certainly work. Keep the temporary fix in mind, or write it down and stick it in your glovebox. You'll need to reset the system again.
Resistors are fairly cheap at Radio Shack. It will cost somewhere around 30 dollars of so and if you ever need to fix any other part of the same vehicle you will have it at your fingertip … s. I cleaned the key and there was no change. You cant really feel it when you are driving, its just noise that gets worse the faster you go. The security light will blink when either door, hatch, or hood is opened and will continue blinking until it is closed. This is the only thing that holds the unit on the car.
But I did disconnect and reconnect both of them and the passenger auto seatbelt still does not work. You can try the thirty minute relearn procedure. You may never have a problem starting it. First try the spare if you have it if that does not work it may be the contacts inside the ignition. Find the orange wire underneath the dash by were your fuse box is at. One connector is grey, and the other is black.
