Saab Problems? Ask a Mechanic for Answers ASAP
Hello and welcome!
The ABS anti lock brake control module, sends a vehicle speed signal to the speedometer. The ABS module receives this signal from the left rear wheel speed sensor.
A problem with the ABS control module, or wheel speed sensors will cause the speedometer not to work and the dash lights you explained to turn on.
There is a known problem with the ABS module in your vehicle to fail and causing your concern. A rebuild ABS module is the most cost effective route.
Ensure that the ABS Fuse #1 is good.
As this is a known problem with your vehicle i can not guarantee just replacing the module will work. Fault tracing the ABS modules power and ground circuits will be needed. and testing for proper AC voltage from the rear wheel speed sensors.
I have not heard of any resets that will work.
If you need any other help please let me know.
Have i answered all of your questions? I only strive for excellent service, If you need anything else at all i will be happy to help you.
Thank you for your question.
