DRB III Does Not Power Up (Blank Screen)

DRBIII ERROR MESSAGES AND BLANK SCREEN
If any of the following error messages appear on the DRBIII screen, refer to the Vehicle Communications for diagnosis and repair.

- cartridge error
- low battery
- ram result failure
- high battery
- keypad test failure

If the DRBIII 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 DRBIII until the condition is corrected.

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





This is a sample of such an error message display.
