DRB Scan Tool Error Messages and Blank Screen

Data Link Connector (DLC):

DRB II BLANK SCREEN
If the DRB has a blank screen, do the following:
- Ensure there is a good body ground at cavity 6 of the data link connector.
- Use the process of elimination: Sequentially substitute another cable, cartridge, and DRB until the condition is corrected.

DRB III ERROR MESSAGES AND BLANK SCREEN
Under normal operation, the DRB will display one of only two error messages: - User-Requested WARM Boot or User-Requested COLD Boot




If the DRB should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display:




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. A minimum of 11 volts is required to adequately power the DRB.

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

DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition.
