Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic tool
The software has been subdivided. For Saab 900 and 9000 (version 44.000 and later) a 10 Mbyte memory card is used. For 9-5, 9-3, 9-3 Sport Saloon and SPS (version 102.000) a 32 Mbyte memory card is required. The subdivision gives assured functionality for systems in older cars and less validation work with new releases. Both cards can sit in the diagnostic tool. You switch between cards by starting the diagnostic tool, waiting until the introduction screen is shown and then pressing:
- Shift
- Left arrow or right arrow
- Shift
For 9-3 Sport Saloon (9440), connect the P-bus and I-bus are directly connected to the data link connector, which requires use of an adapter (CANdi) for the diagnostic tool. The increased complexity of the car has increased the demands on the diagnostic tool. The diagnostic tool has therefore been adapted more directly to various user situations. When Tech2 is used for car models other than the 9-3 Sport Saloon and 9-5 prior to MY06, the CANdi box must not be used.
