Tech 2 Menu Structure

Introduction
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 the SRS (Airbag) or ABS.

1 No communication with the DICE.
If the Tech 2 cannot contact the DICE, neither can it check that the control modules connected to a bus are communicating correctly. The fault is probably because the DICE is not supplied with current or the diagnostics cable is not connected to the DICE (pin 7 of the data link connector and pin 28 of the DICE). The following menu will appear on the Tech 2:

2 No communication with one or more control modules connected to a bus
If the Tech 2 is in communication with the DICE but one or more control modules connected to a bus are missing, the following menu will appear on the Tech 2:

If

Regardless of whether

3 No communication with the SRS (Airbag) or ABS
The fault is probably because the Airbag or ABS control module is not supplied with current or the diagnostics cable is not connected to the control module. If the Tech 2 cannot contact the Airbag or ABS, the following menu will appear:

Changing car configuration
If a new control module connected to a bus is installed in the car,the list will be filled in automatically.

If a control module connected to a bus, such as the CD changer, is removed from the car, the list can be reset to zero with a command under "All systems/Read/Clear Configuration" or "DICE/Read/Clear Configuration".
