If any of the following error messages appear on the DRB screen, refer to the Vehicle Communications section for diagnosis and repair.
-
cartridge error
-
ram test failure
-
keypad test failure
-

-
high battery
If the DRB has a blank screen, do the following:
-
Ensure there is a good body ground at cavity 1 of the data link connector.
-
Use the process of elimination: Sequentially substitute another cable, cartridge, and DRB until the condition is corrected.
Under normal operation, the DRB will display one of only two error messages:
-
User-Requested WARM Boot
-
User-Requested COLD Boot
If the DRB should display any other error message, record the entire display and call the scan tool manufacturer for assistance. This is a sample of such

DRBIII Does Not Power Up
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 2). 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 Test 1A. See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Manufacturer Code Charts/Body Control Module/Symptom Identification (Start
