    I have a 00 Alero. Is it much of a problem going thru the steering column. This is just a pain in the ??? having to wait 10 mintues, and I notice that it only happens in the winter (cold), in the summer time, my security light stayed on, and always cranked up. Now that its cold now, it never wants to start. I really don't care about the security light staying on after the wire is cut.

You can not remove the system. It is intergrated in to the powertrain control module, the body control module and the theft module. It as is tied in to you factory door locks. You can bypass it and disable it but you cant remove it without causing alot of problems

    Ok get acess to the wiring under the steering column. There is a group of 3 small wires in a small wire loom. They are black white and yellow. Start the car with the key and cut the yellow wire the theft lite will come on and stay on but the system will be disabled. If there is a small metal strip in the key its even easier so let me know.

How to reset anti-theft on a 2000 alero


The security, antitheft or lock picture/icon 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 misinterprets 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. This link explains it pretty well.

FUEL PRESSURE WHEN CYCLING THE KEY, NO PRESSURE AFTER THAT


The pump gets power from the pump relay, for 3-5 seconds during cranking, and then once the engine computer sees oil pressure or RPM. The engine computer grounds the relay.

Car wont start code reading is u1000 loss of serial communiocation class 2


most likely cause is the pass lock sensor is bad in the ignition switch. is the security light flashing also? if so then that is a good indication that the sensor will need replacing.

I just replaced the starter in my 2000 olds alero and now it wont start it keep flashing securty....it thinks it is benig stolen....how can I fix this


Most likely you replaced the starter because it wouldn't crank over. If this is correct and the security light was flashing before replacing the starter, then most likely you have a problem with the pass-lock system. If your ignition cylinder is located in the dashboard, you will need to remove it and replace the passlock housing.

1999 Alero anti lock brake light


u can have the light scanned by autozone free of charge. Also in new york state the anti lock system is not part of inspection and can not be a failable issue. Ofcourse your state may be differant. Also the abs light will not turn on for brake pads.. Most common on the olds alero is a bad wheel bearing. The abs sensor is built into all the wheel bearings. The code that u can get out of the car will even tell you what wheel it is that is causing he light to come on. Unless ofcourse its not a wheel bearing and its a internal abs system issue. Let me know what the code is and I will try to get you a pinpoint place to look....
