I have a 2002 saab 9-3 and the traction control light, abs light, and triangular warning lights are all on after the car gets hot and the speedometer stops working when the lights come on. Any ideas?

There is a diagnostic code P1625 for 2001 Saab 9-3 convertible with 88,115 miles. Is this an expensive fix?


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

Abs and traction lights stay on saab 9 3 2005 1.9 vector sport


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,

1999 saab 95 speedometer not working, abs and check engin light comes on


You will need to have your car's ECM (Computer) read by a OBD II scanner to determine what Trouble Code your ECM is giving so a mechanic can properly diagnose the problem. You can go to your local AutoZone store and they can pull the codes out of your ECM for no charge.

Speedo suddenly not working and two warning lights appeared on dashboard one being ABS light warning light.


If the ABS (and likely the traction control) light came on at the same time that the speedometer stopped working, you likely have a faulty wheel speed sensor at the right rear wheel. You can test this by swapping the two rear wheel speed sensors (ABS sensors). If the speedometer then works (but the ABS & Traction control lights stay on), replace the sensor that is now at the left rear (was at the right rear). If no change, you may have a fault in the ABS & Traction control - control unit.
