DRBIII Error Messages and Blank Screen

DRB III ERROR MESSAGES AND BLANK SCREEN
If any of the following error messages appear on the DRB III screen, refer to the Vehicle Communications for diagnosis and repair.
- cartridge error
- low battery
- ram result failure
- high battery
- keypad test failure

If the DRB III has a blank screen, do the following:
- Ensure there is a good body ground at the data link connector
- Use the process of elimination. Sequentially substitute another cable, cartridge, and DRB III until the condition is corrected.

Under normal operation, the DRB III will display only two error messages:
- User-Requested WARM Boot or User Requested COLD Boot

If the DRB III should display any other message, record the entire display and call the STAR Center.
