6 Check the connectors of the for
connection.
Check the connections between the
MCU Board and Registration Sensor.
Are P/J23 and P/J232 connected
correctly?
Go to step 7. Reconnect the
connector(s) P/
J23 and/or P/
J232 correctly.
7 Check the Left Side Harness Assy for
continuity.
Disconnect J23 from the MCU Board.
Disconnect J232 from the Registration
Sensor.
Is each cable of J23 <=> J232
continuous?
Go to step 8. Replace the
Left Side
Harness Assy.
(PL 3.1.18)
8 Disconnect J23 from the MCU Board
and measure the voltage across P23-3
<=> ground on the MCU Board.
Is the voltage about +3.3 VDC?
Go to step 9. Replace the
MCU Board.
