3.18.1 DRBIII
T
DOES NOT POWER UP
If the LEDs 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 DRBIII
t
. Check for
proper ground connection at DLC cavities 4 and 5.
If all connections are proper between the DRBIII
t
and the vehicle or other devices, and the vehicle
battery is fully charged, an inoperative DRBIII
t
may
be the result of faulty cable or vehicle wiring.
3.18.2 DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the
display. Adjust the contrast to compensate for this
condition.
