DRB III ERROR MESSAGES AND BLANK SCREEN
Under normal operation, the DRB III will display one of only two error messages:
User-Requested WARM Boot (Press MORE and NO at the same time)
User-Requested COLD Boot (Press MORE and YES at the same time)
If the DRB III should display any other error message, record the entire display and call the S.T.A.R. Center for information and assistance.
DRB III DOES NOT POWER UP
If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB III.
If all connections are proper between the DRB III and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB III may be the result of faulty cable or vehicle wiring. For a blank screen, refer to the appropriate body diagnostics.
DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition
SOME DISPLAY ITEMS READ "---"
This is caused by scrolling the DRB III display a single line up or down. The line which was scrolled onto the screen might read "---". Use the Page Down or Page Up function to display the information.

- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
