SECTION VI
Additional CANdi Troubleshooting Tips
Transformer voltage output test using DVOM:
• Set DVOM to Volt setting.
• Probe cable end inside and outside the terminal.
• Twelve volts is the minimum.
Updating the CANdi module:
IMPORTANT
You must use a 32-megabyte (32-MB) PCMCIA card in the Tech 2, not a 10-megabyte (10-MB) card.
You must update the 32-MB PCMCIA card before connecting the CANdi module to the Tech 2.
Always disconnect the CANdi module from the Tech 2 before downloading software updates to
the PCMCIA card.
The CANdi module is capable of storing up to three different software versions.
• Will the CANdi module require updates?
Possibly. The CANdi module ships complete with software, but possibly not the most current version.
• Be sure to update the Tech 2 with the latest software before using the CANdi module.
The CANdi module will compare software and look for a possible update from the Tech 2. When you
update the Tech 2, any software updates for the CANdi module will download to the PCMCIA card.
The CANdi module will automatically receive updates each time it is connected to the DLC and Tech 2 at
power-up. Therefore, it is very important that you always run the latest available software version when
using the CANdi module.
