Component Tests and General Diagnostics
Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic

DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION.DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR

DRB III(R) Does Not Power Up (blank Screen)
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.
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. Perform the "Blank Screen" test under Vehicle Communication.
Display Is Not Visible
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition.
