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 Testing and Inspection, Non-Diagnostic Trouble
Codes in this section.
Display is not visible
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition.
Enhanced Accident Response (Highline CTM Only)
ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors.
The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to
unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key
has been cycled to the "off" position, normal operation will resume.
