Question about 2001 Oldsmobile Alero
I have a 1999 Oldsmobile Alero. I was driving down the street, coming to a stop sign and looked at the speedometer because I felt I was going a little fast for the stop. As I was coming to a stop, looking at the gauges, every single one went to zero.. as if the car was off. I continued to drive the car to my home, with no clue on how fast i was going, how much gasoline I had or what temperature the car was. The light on the gear indicator went off, and the miles do not add anymore. Every single light that could turn on in the dash ( Traction, ABS, Security, Coolant, Battery, Service Engine Soon, and Check Engine), turned on when the gauges dropped to zero.
When I got home and turned the car off, I took the key out of the ignition and the odometer stayed on. Along with the battery light on the far right side of the instrument panel next to the speedometer. Every other light went off. It seemed as if the starter was still engaged. So I popped the hood, and unplugged the positive from the battery. I went to sleep as it was night time.
The next day I plugged the Positive back into the battery, and turned the car on. All of the lights that were on the day before had gone off, except for the battery and the odometer. I drove the car like this for a couple of days.
All of a sudden, another situation as when it first occured, I went to look at the speedometer thinking it worked, trying to figure out how fast I was going, and the car chimed three times, and the gauges started to work again. It started to read miles and only had the security light and traction off light on.
If someone has any clue what this might be, please help. I am in DESPERATE need of some sort of help, as I have absolutely no idea.
I appreciate your work, Jeremy.
P.S. - I went to Auto-Zone and had my alternator checked, it was strong.
- I checked every fuse in the car.
- Cannot check every relay... would not have a clue which relay it would be.
- Tried to have auto zone diagnose from inside the car, came up with no codes.
Could be lose connection on the back of the instrument cluster ,which means you would need to pull it out of the vehicle . Check pin fit to instrument cluster . for the B+ voltage suppy an ground connection's .
You said autozone - Tried to have auto zone diagnose from inside the car, came up with no codes. That's in the PCM - engine computer . There scan tool will not communicate with the instrument cluster ,which is also a computer in it's self. Need a factory scan tool to check instrument cluster.
Speedometer and/or Odometer Inaccurate

Did you complete the repair?
Go to Instrument Cluster System Check
With a scan tool select the instrument panel cluster, data display, gear status.

The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.
