STATE DISPLAYS Mode
- This display enables technician to view conditions at the signal level. The 2 types of signals used are analog and digital. Analog signals are monitored at pins corresponding to vehicle harness splices (e.g., fuel pump relay).
- Digital signals correspond to data transmitted by the system controllers. Both signals are displayed in common units (e.g. temperature), but this information is not relative to diagnostic intent. Use up and down arrow keys on DRB-II to scroll through displays available.
- The following STATE DISPLAYS are available on the DRB-II:
- Module Information:
Allows technician to read ECU part number and application.
- Engine Sensors:
Allows technician to look at various engine sensors and system controllers during engine operation.
- Inputs/Outputs:
Allows technician to read input and output states of various switches and sensors that affect ECU operation.
- Monitors:
This screen shows technician sensors and system controllers that affect fuel control, spark advance, RPM and A/C relay. There are 4 different screens available. For example, screen No. 1 will show: AIRFLOW SENSOR, O2 SENSOR, BATTERY, FUEL INJECTOR, THROTTLE POSITION SENSOR (TPS), BAROMETRIC PRESSURE SENSOR, COOLANT SENSOR and RPM. All of these inputs affect fuel control.
- Custom Display:
This screen allows technicians to set up their own custom display. Two custom display screens can be programmed into DRB-II.
