GENERAL INFORMATION
3.5.1 DRBIII DOES NOT POWER UP
If the LED's do not light or no sound is emitted at

cable. Check the vehicle battery voltage (data link
connector cavity 16). Check for proper ground con-
nection at DLC cavity. 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, and inoperative
DRBIII may be the result of a faulty cable or
vehicle wiring. For a blank screen, refer to the
appropriate body diagnostics manual.

condition.
