DRBIII Error Messages and Blank Screen

DRBIII ERROR MESSAGES
Under normal operation, the DRBIII will display one of only two error messages:





^ User-Requested WARM Boot
^ User-Requested COLD Boot

If the DRBIII should display any other error message, record the entire display. Further scan tool diagnosis will be required.

DRBIII DOES NOT POWER UP (BLANK SCREEN)
If the LEDs 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. A minimum of 11 volts is required to adequately power the DRBIII.

If all connections are proper between the DRBIII and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRBIII may be the result of faulty cable or vehicle wiring. For a blank screen, refer to appropriate diagnostics.
