DRB Test Functions: Notes
NOTE:
DO NOT touch DRB keypad during power-up sequence, or an error message will result.
NOTE:
Because DRB is grounded through its connector, only one volt-ohmmeter test lead is required when using volt-ohmmeter option. DRB volt-ohmmeter should only be used when specified by diagnostic procedure.
- DRB must be in LH CLIMATE CONTROL menu to perform diagnostic tests. At LH CLIMATE CONTROL menu, fault codes can be retrieved and DRB test functions can be performed.

- All DRB character positions will light, and copyright information will appear on screen for a few seconds. After a few seconds (no error messages present), the DRB menu will appear. If DRB screen is blank, see REPAIRING DRB BLANK SCREEN.
- At DRB menu, press "4" (SELECT SYSTEM) key to enter diagnostic test program. At SELECT SYSTEM menu, press "9" (LH CLIMATE CONT) key to enter climate (A/C-heater) control part of the DRB program. After a few seconds, the LH CLIMATE CONTROL menu will appear. The screen will display a menu of the DRB test categories for the A/C-heater system.
