1996 Olds Achieva: Security light flashes upon startup

1996 Olds Achieva - Ongoing issue: Security light FLASHES upon start up and car stops running. Gas is restricted from injectors. (When I can get it to start, it runs fine. While running, security light is on SOLID sometimes and OFF other times - never FLASHING. Only presents a problem on startup when it FLASHES. For about a month it took several tries to start sometimes but would eventually start. Last night it refused to start at all, even after leaving key engaged and turned to run position for 20 minutes in an attempt to "reset" the computer (read this on a web site). Tried disconnecting the yellow wire in the ignition cluster of 3 wires (read this on a web site) but it did not solve problem. Car will turn over but not stay running do to FLASHING security light.

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

Looks like the TDM in the security system (VATS/PassKey) is having problems, it's typical on those cars and it can get worse till the car wont start anymore. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

96 olds achieva wont start unless daylight running lights come on when ignition switch is turn on


You may have a key that has a transponder hidden in the plastic key head. If the security light is on, that means that you DO have an antitheft feature that is not working properly and is most likely causing your problems. Take a look at this link, it explains the security issue and some symptoms. Along with some DO IT YOURSELF solutions.

98 olds acheiva won't start, replaced starter and solenoid and tried the turn key on for 10 minutes then turn off and start, did not work I see no chip in my key but security light stays on and car...


If the security light is on, then it can only be one thing. The security system is failing and immobilizing your car. Go to this link and read up on the problem. The security light is a dead give away that the security is messed up. If you have no little black chip in the shaft of your key, then this means you must have a passlock that runs on the transponder. You need the PERMANENT fix from this site. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Ignition keeps going into security car starts then stalls and security idiot light flashes


ignition switch problems on these cars are notorious, you can bypass the anti-theft module by placing a resistor inline so that the module 'thinks' the correct key is not an attempt to steal the car. the anti theft is located behind the glovebox and the resistor costs 15 cents at radio shack, not as hard to do as it sounds and it fixes it for good.

The car fires but stops immediately


I had a problem with a 97 Achieva recently.Someone else replaced the PCM/ignition switch and passlock sensor.I replaced the ICP.Engine would turn over but wouldn't start and the security lamp was dim and flashing and then it would go solid.I tried the wait 10 minutes thing but,the light would never go off! I put the original passlock sensor back onto the lock cylinder. But this is what fixed the problem.I cleaned the contacts on the black wires and green on the ignition switch with tv tuner cleaner! After I cleaned those contacts the security light was flashing brightly.So I turned the key to run and left it there.After a few minutes it stayed on solid.I waited about 10 minutes but the light never went out.So I turned off the switch and then tried starting.It started right up and the security lamp flashed and then went off.Has started every time since.Note:I also scraped the pins that I cleaned with the cleaner with a knife.

1996 Oldsmobile Achieva: Security light flashes upon startup


Here is what you do, but only when the SECURITY light flashes - if it is always ON or OFF it's no use.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes ( SECURITY light will flash for 10 minutes and then stay on SOLID)
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the ignition OFF.

Start the car normally.
It has relearnt the keycode and you're good to go.
NOTICE - it takes 30 minutes to relearn, that's THREE cycles of ON - 10 minutes - OFF.

Good luck.

Security light flashing and car won't start now


does it start at all, or does it run for about 1 second and shut off? if the latter, then it's the passlock system, and he could have a defective key or security module. the keys have a predetermined resistance value which activates the passlock system to prevent hotwiring. If it is the passlock system, then sometimes you have to wait 15-20 mins for it to reset before starting the engine.

Security light flashes car wont start


You need to go to GM and find out what defective part is causing this, the most common is the sensor in the ignition lock cylinder fails, then when you try to start it doesn't send a usable signal from the key chip to the electronic module that controls the security system and it locks you out.
