Action/Troubleshooting
VENT +6V FAIL Vent Fail. Monitoring
Only
In the Service Software / Vent Interface Bd Power Diagnosis, view the "Vent Int Bd 10VA Voltage" from
Board Supplies:
If "Vent Int Bd 10VA Voltage" reads "OK, and +6.0Vdc reads "Fail", replace the VIB.
If "Vent Int Bd 10VA Voltage" reads "Fail" and the "Vent Int Bd 10VA Voltage" from the Anes Cntrl Bd
reads "OK", Check cabling between ACB and VIB.
VENT 1.22V FAIL Vent Fail. Monitoring
Only
In the Service Software / Vent Interface Bd Power Diagnosis, view the "Vent Int Bd 10VA Voltage" from
Board Supplies:
If "Vent Int Bd 10VA Voltage" reads "OK, and 1.22 Vdc reads "Fail", replace the VIB.
If "Vent Int Bd 10VA Voltage" reads "Fail" and the "Vent Int Bd 10VA Voltage" from the Anes Cntrl Bd
reads "OK", Check cabling between ACB and VIB
VENT -6V FAIL Vent Fail. Monitoring
Only
In the Service Software / Vent Interface Bd Power Diagnosis, view the "Vent Int Bd 10VA Voltage" from
Board Supplies:
If "Vent Int Bd 10VA Voltage" reads "OK, and
If "Vent Int Bd 10VA Voltage" reads "Fail" and the "Vent Int Bd 10VA Voltage" from the Anes Cntrl Bd
reads "OK", Check cabling between ACB and VIB.
VENT ADC VREF FAIL Vent Fail. Monitoring
Only
In the Service Software / Vent Interface Bd Power Diagnosis, view the "Vent Int Bd 10VA Voltage" from
Board Supplies:
If "Vent Int Bd 10VA Voltage" reads "OK, and 3.2 Vdc reads "Fail", replace the VIB.
If "Vent Int Bd 10VA Voltage" reads "Fail" and the "Vent Int Bd 10VA Voltage" from the Anes Cntrl Bd
reads "OK", Check cabling between ACB and VIB.
