Tech 2 menu structure
| 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:
If <ENTER> is pressed, the Tech 2 will again try to contact the DICE. If the <EXIT> key is pressed, the Tech 2 will try to contact the selected control module (the reason for this is that it should be possible to contact the SRS (Airbag) or ABS even if the DICE is not present).
| 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 <OK> 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 <ENTER> or <EXIT> 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 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”.
