Error Messages and Codes
5 1.Perform the Registration Sensor
test (page 4-30): Service Mode >
Engine Diag > Sensor Test > Regi
Sensor.
2.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 1. Check the wiring harness
connectors P/J29, P/J292, and P/
J2922 between the MCU Board and
the Registration Sensor.
2.Are the connectors securely
connected?
Go to step 7. Reconnect the
connectors.
7 Check the Registration Sensor
Harness for continuity.
1.Disconnect P/J292 from the Regi
Sensor and P/J2922 from the Right
Side Harness.
2.Check continuity between P/J292
<=> P/J2922.
Go to step 8. Replace the
Registration
Sensor
Harness.
8 Check the Right Side Harness for
continuity.
1.Disconnect P/J29 from the MCU
Board and P/J292 from the Regi
Sensor Harness.
2.Check continuity between P/J29 <=>
P/J292.
Go to step 9. Replace the
Right Side
Harness.
9 Check the Registration Sensor for
continuity.
1.Disconnect P/J29 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J29-8 pin?
Go to step 10. Replace the
MCU Board
(
page 8-86).
10 Check the Registration Sensor signal.
1.Measure the voltage across ground
<=> J29-10 on the MCU Board.
2.Does the voltage change when the
Actuator of the Registration Sensor
is activated?
Replace the
MCU Board
(
page 8-86).
Replace the
Regi Sensor
(
page 8-43).
11 1.Perform the Tray 1 (MPT) Feed
Solenoid test (page 4-53): Service
Mode > Engine Diag > Motor Test >
Tray 1 (MPT) Feed Solenoid.
2.Does the Solenoid operate properly?
Go to step 15. Go to step 12.
