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

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

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