Abs traction control Saab 2001 9-3

the ABS system is defective, probably one or more of the sensors.

Traction control system works with the ABS sensors to monitor to monitor traction slippage.

The stability control system uses the abs wheel speed sensors to detect when a wheel is losing traction and would presumably apply the brake on that wheel to maintain traction.

The system is the Vauxhall (GM's British operation) version of a traction control system further refined by Saab's engineers.

Stability control failure means the system will no longer be available to assist the driver maintain traction.

P1625 means that the engine computer has lost communication with the antilock brake and/or traction control computer for at least 3 seconds. How expensive this is depends on why it has lost communication, It could be something as simple as a loose connection at a wiring connector or a broken or shorted wire in the PCI bus circuit inside the wiring harness. (Which may require considerable diagnostic time to find) or it could be an internally failed ABS module.

Recommendation:
If you are NOT experiencing ANY of the symptoms below, I would simply clear the code and move on.... It is an intermittent fault that you will most likely not find very easily. If you ARE experiencing ONE OR MORE of these symptoms, then the problem needs to be diagnosed by checking the ABS module's ability to communicate with a scanner while testing the PCI Bus circuits.

Other possible symptoms of Diagnostic Trouble Code (DTC) P1625
• Speedometer malfunctioning
• Traction Control malfunctioning
• Antilock Brake System malfunctioning or ABS light on
• Cruise Control malfunctioning

I have a 2001 Cadillac Deville with 105,000 miles. The ABS and Traction Control light stay on. What could be the problem? Could I reset the ABS and Traction Control light?

The abs light , when on turns off the traction control thats why that light is on,once the abs is repaired the traction light will go out, you need to first have the computer scanned for codes, the codes for the abs are stored in the abs computer, these codes will tell you what part of the system is not working. most of the time its a wheel speed sensor but scanning the codes is needed to find out,

your traction control mechanism uses the abs breaks to slow the spinning and give you better traction. i'm thinking your traction control sensor has gone bad

abs control module is bad

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

The traction control system uses the abs wheel sensors to detect wheel speed if the abs light is on the entire abs system will disable giving you regular braking but it will also stop feeding info to the traction control

An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
