Abs light on, Speedometer not working and odometer not tracking miles
Please help. New to the group. I have a 2002 sc430 with abs light on, traction control on, speedometer not working and odometer is not tracking miles. I have replaced ECM and checked all known fuses/relays. Diagnostic computers will not communicate with antilock break system but will connect to engine. I have no idea what to do next. Please advise.

My guess would be a speed sensor issue since that would effect ABS. Possibly a broken gear in the speedometer system.
Since you are in Tennessee, was the car involved in any high water with the recent hurricane?

I had the same things happen to my 02 this summer. It turned out to be the skid control module. Techstream would not talk to the ABS system.
I sent the unit out for repair, when it came back it still didn't work. Repair company said some other part of the system may be frying the computer.
I then carried the car to Lexus to be checked out. Results were that only the skid control module was bad. They replaced that and the problem went away.
One question which may not mean anything : Is the steering stiff when barely moving ?

Thank you for all the input! No, it has not been exposed to water or had water damage. This all started a few months back. I have 67xxx miles on the car.
Yes, the steering is difficult....

The Brake light was on in my car but the traction control was not.
Maybe someone with service manual can check to confirm ; I think that I saw where 2 wires from the skid control module
go to the solenoid on the power steering pump. Replacing the skid control did not correct stiff steering at slow speed on my car.
I hope you find your problem is maybe a wheel sensor like has been mentioned.

Update
Update: the skid control module (abs ecu) replacement fixed all issues!!!! I purchased a refurbished skid control module from eBay and installed it. It is a pain in the @ss to get the old one out. But it fixed all symptoms! Thank you for the advice.

The original poster solved the problem by replacing the ABS Computer
