SECTION VI TROUBLESHOOTING
2005 Tech 2 User’s Guide VI - 13
The screen shown in Figure VI-27 is displayed when the Tech 2 does not detect the CANdi module. This
can occur under the following conditions:
• The CANdi module is not connected to the Tech 2, or
• A problem occurred during start-up that prevented the Tech 2 from configuring the CANdi module.
If this occurs, power the Tech 2 off and start again. If the problem persists, follow the troubleshooting tests
on page VI-15.
It is also possible to connect a CANdi module after the Tech 2 has been powered up via the VCI. If this
occurs, the Tech 2 will not detect CANdi module and will not properly communicate, even if the LED is
flashing on the CANdi module. Power off the Tech 2 and start again.

CANdi module not detected screen
The screen displayed in Figure VI-28 occurs when the Tech 2 loses communication with the CANdi
module. This could be a result of the following:
• VCI not properly seated in the Tech 2 slot
• DLC cable not properly connected
• Poor Burndy cable connection to the CANdi module
• Worn or damaged cable that results in a poor connection between the CANdi module and the VCI
If this occurs, check all Tech 2 and CANdi module connections, power off the Tech 2 and start again.
If problem persists perform the troubleshooting tests on page VI-15.
