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 any of the systems not connected to the bus.

1 No communication with the DICE.
If the Tech 2 cannot contact the DICE, it will not be able to check that the control modules connected to a bus are communicating correctly either. 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:







If is selected, Tech 2 will again attempt to make contact with DICE. If is selected, Tech 2 will attempt to make contact with the selected control module (as Airbag and ABS must be able to be contacted even when DICE is not present).

No communication with one or mere control modules connected to a bus
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 is pressed, a list of the control modules fitted as original equipment on the car will be displayed. "OK" is shown on the right of each control module if it is communicating correctly and "Missing" if the control module is missing from the bus.

Regardless of whether or is pressed, the Tech 2 will try to communicate with the selected control module. If the Tech 2 cannot contact the selected control module, the following menu will appear:

3 No communication with any of the systems not connected to the bus.
The fault then probably is caused by the control module not being supplied with power or that the diagnostic cable is not connected to the control module. If Tech 2 cannot make contact with the system, the following menu will be displayed:

Changing car configuration

If a new control module connected to a bus is installed in the car, the list will be appended 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".
