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.
If the Tech2 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 fault screen may appear. If this occurs, power off
the Tech2 and attempt to reprogram the CANdi module again. If the problem persists,
incorrect CANdi software may be present on the Tech2 PCMCIA card. Connect the Tech2
to the TIS2Web computer and download a new version of the software.
