DRBIII Does Not Power Up (Blank Screen)

DRBIII 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. 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 Body Control Systems.
