    1999 Saab 9-5 SE ABS Lights

    I have the ABS lights on and could really use some advice. Car is a 1999 Saab 9-5 SE … 135k miles

    After starting the car and the car going through its checks, there are no dash/warning lights on at all. When I start driving (either forward or reverse or rolling in neutral) and at 8 mph (according to my GPS) the ABS lights come on, including Brake, TCS and ! The speedo, tach, and other gauges work throughout. The control module has been checked good by BBA, the 4 wheel speed sensors are new, and the tone rings are clean. The #26 7.5 amp and #1 60 amp fuses, tire pressure, brake fluid and brake thickness are all good. I’ve checked the continuity and voltage on the front speed sensors – both check good. I tried disconnecting each speed sensor, one at a time, and each resulted in all the lights coming on. The are no codes on an OBD and unfortunately I don’t have a Tech II.

    I looked through the forums and didn’t see a situation like mine. I have a state vehicle inspection coming up and would appreciate any advice.

    Sounds like a wheel speed sensor or the associated reluctor ring. The reluctor rings crack, being clean is no indication that they aren't cracked. The ring forms a magnetic circuit and the crack breaks that circuit.

    Thanks for the feedback. Things are pointing toward a bad reluctor ring. I take it there is no way to test the rings while still on the car? The CV axles for the early 9-5s aren't available anymore, but looks the the rings are.

    Thanks. Regards, Gary

    Yes there is a way of testing the rings. Put the car on a lift, switch on and then spin each wheel separately, the one with the cracked reluctor should be the one that brings the light on. However, I don't know enough to be certain of that and it isn't a practical DIY approach anyway.
