there is no code, if you turn the key and try to start the car and the security light comes on do not keep cranking it because you will just waste the charge in the battery. turn the key like your starting the car to the position where the lights on the dash come on and let it sit for 10 minutes or until the security lite stops blinking then turn the key to off position and try to start the car.. it is really common on these piece of junk cars and if you have an after market key good luck because it will happen a lot and at the worst times possible
Turn the key to the on position, wait ten minutes, then it will turn over.
It would be very rare for a P1684 code to turn the light on.
Sometimes my sons 2001 Grand Am does that. It has to do with the Security System. Turn the key to ACC the Security light will start blinking and will continue to do so for 10 minutes. At that time the Security Light will stay on. At that point you can start you car. This works for him Good Luck.
The light is on because the air bag computer has detected a malfunction and set a code. The failure will have to be repaired to get the light off.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
If Its an older Grand Marquis its easy. Find the knob that you pull out to turn on the headlights. Now, just turn it clockwise and the light will turn off!
If your security light is flashing, then you have had what is referred to as a "bad timing cycle" with your Passlok security system. Turn the key to the ON position, and wait until the security light stops flashing - This takes exactly 10 minutes.If the security light WAS flashing, then the 10-minute trick is only a temporary fix - You will need to have your ignition switch replaced.
i also have Pontiac grand am, mine is a 2001. The pass lock sensor sets off the security light which cuts off gas to the engine, which is a theft deturent. My problem was fixed when i got a new stereo and the one thing that was replaced was my chime module, so we think mine was a electrical problem. But get your pass lock sensor looked at because that is what controls the security light.
The factory alarm causing the issue would be the security light flashing above the RPM guage. If the security light is flashing and the car will not start, follow the directions listed below. To reset the factory alarm, turn the ignition switch to the "on" position NOT the start position for 15min. You will see the security light go off after 15min.
how do you turn off security light on 1989 Buick Rhetta
When you turn the key off and lock the doors, there will be a red light on the top of the dash that flashes while the alarm arms.
this happens to me every time i wash the car...solution is to put the key in the on position and wait for 10 minutes. it will clear the path lock sensor and turn off the light.
