CANdi Module Troubleshooting
The following troubleshooting information applies only to the CANdi module. This application is
unavailable for most vehicles at the time of writing.
Figure VI-25 shows the screen that the Tech 2 displays during programming of the CANdi module.
If the Tech 2 loses power during programming, the CANdi module will not be properly programmed. The
CANdi module will be automatically reprogrammed when power is available.

If a fault occurs during reprogramming, a screen like the one shown in Figure VI-26 may appear. If this
occurs, power off the Tech 2 and attempt to reprogram the CANdi module again. If the problem persists,
incorrect CANdi software may be present on the Tech 2 PCMCIA card. Connect the Tech 2 to the TIS
terminal and download a new version of the software.

NOTE: Do not perform a VCI self-test while the CANdi module is connected. If the CANdi module is
connected and an error screen occurs, disconnect the CANdi module from the Tech 2 and
perform the test again.
