Step
Checking the connectors of the Exit Sensor in the FUSING
UNIT for connection.
Check the connections between the PWBA MCU and
FUSING UNIT.
Are P/J17 and P/J171 connected correctly?
11
Checking the HARNESS ASSY FUSING UNIT MG AIO for
continuity.
Remove the FUSING UNIT.
12
Disconnect J17 from the PWBA MCU.
Is each cable of J17 <=> P171 continuous?
NOTE: P171 is attached to the frame.
Checking the power to the Exit Sensor in the FUSING UNIT.
Disconnect the connector of J17 on the PWBA MCU.
13
Is the voltage across J17-1pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Checking the Exit Sensor for operation.
Check the voltage across J17-3pin <=> ground on the
