Tech 2 Menu Structure: Introduction: Notes

WARNING: This page is about a different car, the 2002 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

Regardless of the control module selected in the Tech 2 menu, the Tech 2 will first contact the DICE to check that all control modules connected to a bus are communicating correctly. A warning is given by the Tech 2 in the event of a fault. The Tech 2 can detect the following faults:

  1. No communication with the DICE.
  2. No communication with one or more control modules connected to a bus.
  3. No communication with any of the systems not connected to the bus.
