DRBIII(R) Does Not Power Up (Blank Screen)

If the LED's do not light or 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 a faulty cable or vehicle wiring. For a blank DRB screen, refer to Powertrain Management.
