the secret to the security light

[TheBulldog]

i found out the most brilliant thing recently when my car refused to do anything when i put in the key and the security light flashed. i had recently researched it and found out it was the two wires in my ignition were probably frayed and the dealer would want to rip me off and put in a new ignition cylinder. i though i would take care of it myself so i started pulling apart my steering wheel. i didn't have a wheel puller so i gave up. i discovered that our cars have the pass II system that reads the resistance in the chips in our key, while this makes the car almost impossible to steal, it also makes an older car hard to start. with all the friction going on in the steering wheel with the key being turned, the wheel turning and tilting, the wires sometime get frayed, so naturally i decided to pull my dash apart and see what i couls do. there are two little white wires coming down fromt the steering wheel, bundles with the airbag wires. once those are located all you have to do is unplug it. this causes the computer to read infinite resistance so it just make the security light stay on forever but your car will start just like it used to. now all i have to do is figure out how to disable that stupid bulb ;)

I wasn't aware you could just disable it that way. On my car I installed a remote start and tried the resistor with a relay but the relay wouldn't stay closed long enough for the resistance to be measured, so I just cut the 2 wires and made a loop with the resistor, 2 wires aren't connected from the ignition, that will double the resistance and shut down the fuel pump and starter. You can get one at just about any electronic place, I went to a car electronic installer, they measured the resistance in my key and gave me a resistor for a few dollars
