Hi All
I was on my way to work today my security light came on and stayed on. I got to work and locked and unlocked while the car was still running, and the light stayed on. When I shut the car off and the light goes off. Started the car again and light came right back.

Any ideas on what it could be?

Thank you
Keith

Hmmm...that could be caused by a bad key chip, but that's rare. More than likely, it's the (security system) wiring in the lock tumbler that has come loose or broken.

Not possible. The chip in the key (passkey or vats) will not set the light while driving. It's ignored after start.

The most likely candidate is the trunk lock cylinder tamper circuit. If your car has the under-lid carpet under the trunk lid, remove it. Starting at the lock cylinder, follow the mechanical cable from there to the connector where it has an electrical wire. Disconnect that electrical connection. Does the light go out?

This circuit is designed to set when someone tampers with your lock cylinder or tries to use a slide hammer on it. The tab on the cylinder will break, grounding the circuit, and setting the light/alarm. Over time, that tab becomes weak and breaks, setting the light.

Just today, my car exhibits the same symptoms as the thread starter. Security light stays on, never had that problem before. I'm wondering if this could also be caused by a slim jim at one of the doors.

I'm not aware of any tamper switches in the doors. That's a trunk and hood only feature. Interior entry is guarded by the door jamb switches themselves.

Try your hood switch (opposite the battery above the driver's headlight) or the trunk switch I described above. Disconnect them one at a time, see which one kills the light.

Hi and thank you for the help.

My vehicle does not have carpet covering the trunk lid. There are two connectors at the trunk lock. One is for the power actuator and the other must be for the security system. I disconnected the "security" connector and the light still stays on.

I looked under the hood above the drivers head light for a switch but could not find one. I did see a square black box with a wire loom exiting mounted center above the ac condenser near the hood lock. Followed that to a yellow connector located behing the computer on drivers fender wall and disconnected that and the light still stays on. Tried disconnecting another connector in the same area, no change. Also used a key that has had little use over the years- light still on.

Please let me know if I did not follow your instructions correctly and disconnected the wrong connectors.

Thanks

Bob

Please re-connect your airbag impact sensor and don't make a habit of disconnecting any part of the airbag system until you disconnect the battery and let the circuits discharge for about 30 minutes. Any yellow tag or yellow harness would be the same rules.

You're looking for a vertical plunger (plastic) somewhere under the hood area near the front edge of where the hood closes.

The connectors were re-connected after the experiment failed, so no need for concern about my air bag system.

There is no vertical plunger switch under the hood of my vehicle. Never noticed one there and I'm the original owner.

Light will get some black tape over it, that is my solution for now.

Big concern and big caution. The airbag system is very dangerous to you, and very expensive to repair. That's why I was so specific about what you did. That front impact sensor is one of the major components of the system.

As far as your hood pin is concerned, you may not have that feature. I'll have to compare my two cars (when the other gets home) and see what my SLE has in comparison. It may be the hood pin only illuminates the 'hood ajar' on the DIC of the SSE/SSEi, but that would take some book looking to determine for sure.

My '99 SLE does not have a "hood ajar" warning nor the switch you reference.

Prior to this security light issue and ongoing now, is that my car cranks in the morning while cold but I'm having trouble starting it. It takes 3-4-5 attempt for it to start. Coincidence-?- I never had this problem starting cold ever!! I've found no vacuum hose leaks. :helpsmilie:

Sounds like a bad ignition lock cylinder to me. If the light comes on with the engine running, it's a probem with the Vehicle Theft Deterrent (VTD). If the light comes on with the ignition switch off, it's a problem with the Content Theft Deterrent (CTD). They are two different systems that both have the ability to turn the same light on, but CTD can only turn the light on when the ignition switch is off.

Easiest way to fix it is to read the key with an ohmeter to get the resistance and buy a 5-pack of resistors at Radio Shack ($1) then wire on in under the dash. There are instructions on doing this elsewhere on this site.

Hey guys thanks for the info Im gonna take a look at my trunk today cause my light is still on. I know my key is fine cause I tested it not to long ago. I know my wires in the lock tumbler are fine cause I just had to replace them a few weeks back.
Thank you for the ideas I will be back to let you know what I find.

Check the connection under the dash.

Being fed up with the starting issue, (cold start cranks 4-5 times and sometimes it starts the first try). I took it to Azone for a scan and the crank position sensor code was stored. So I bought one and hopefully that will take care of the problem.

Now, I have to search the forum on how to do the CPS job.

Wish me luck 8-[

I thought there wasn't a code that was set for crankshaft position sensor. That's what makes them hard to troubleshoot.

Is there a code?

There must be because I don't think the Autozone was lying to me. Anyway, I'm going to have to bring it in and pay a mechanic. Getting that large nut off the pulley and immobilizing the crank in my driveway seams difficult to do.


I'm thinking of selling this car :angry4:

After doing much reading up on the CAS, I decided to try a few things before replacing. Because the problem is intermittent and happens u[on a cold start, I suspect a faulty wiring condition. So I "worked" on the connector at the CAS and ICM, sometimes twisting the wire and cleaning the connectors will correct a bad connection. Next, I read on this site that after removing the HB pulley "rust/particles" were observed either on the CAS or pulley. I noticed a vent slit in the plastic housing that covers the CAS. I put a nozzzle on my air compressor and blasted air thru that opening in the hope that any "debris" get dislodged. Also, I cleared the computer codes and played around with the wiring under the steering column.

I used a test bulb at the fuel injection wiring while cranking the engine and it lit. The engine fired up first try this AM. However the Security light is still on full time.

The last thing I want to do is bring this car to a mechanic and pay $200+ to install a $30.00 part. I'd probably try and remove the HB pulley and die trying before I go that route :bow:

Wow! I would rather pay $230 than die, but that's just me I guess. :)
