Error Messages and Codes
5 Perform the Registration Sensor test
(page 4-29): Service Mode > Engine
Diag > Sensor Test > Regi Sensor.
Does the number on the Control Panel
increase by 1 every time the Actuator
of the Registration Sensor is
activated?
Go to step 11. Go to step 6.
6 Check the wiring harness connectors
P/J23, P/J232, and P/J2322 between
the MCU Board and the Registration
Sensor. Are the connectors securely
connected?
Go to step 7. Reconnect the
connectors.
7 Check the Registration Sensor
Harness for continuity.
1. Disconnect P/J232 and P/J2322.
2. Check continuity between P/J232
<=> P/J2322.
Go to step 8. Replace the
Registration
Sensor
Harness.
8 Check the Right Side Harness for
continuity.
1. Disconnect P/j23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
Go to step 9. Replace the
Right Side
Harness.
9 Check the Registration Sensor for
continuity.
1. Disconnect P/J23 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-8?
Go to step 10. Replace the
MCU Board
(page 8-87).
10 Check the Registration Sensor signal.
1. Measure the voltage across ground
<=> J23-10 on the MCU Board.
2. Does the voltage change when the
Actuator of the Registration Sensor
is activated?
Replace the
MCU Board
(page 8-87).
Replace the
Feeder
(page 8-43).
11 Perform the Tray 1 (MPT) Feed
Solenoid test (page 4-53): Service
Mode > Engine Diag > Motor Test >
Tray 1 (MPT) Feed Solenoid.
Does the Solenoid operate properly?
Go to step 15. Go to step 12.
12 Check the wiring harness connectors
P/J23 and P/J236 between the MCU
Board and the Tray 1 Feed Solenoid.
Are the connectors securely
connected?
Go to step 13. Reconnect the
connectors.
