Error Messages and Codes
14 Check the Registration Sensor signal.
1. Measure the voltage across ground
<=> J29-10 pin 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
Registration
Sensor
(page 8-43).
15 1. Perform the Main Motor test
(page 4-41): Service Mode >
Engine Diag > Motor Test > Main
Motor .
2. Does the Motor operate properly?
Go to step 19. Go to step 16.
16 1. Check the wiring harness
connectors P/J22 and P/J222
between the MCU Board and the

2. Are the connectors securely
connected?
Go to step 17. Reconnect the
connectors.
17 Check the Right Side Harness for
continuity.
1. Disconnect P/J22 from the MCU
Board and P/J222 from the Main
Drive Assembly.

(page 8-86).
19 1. Perform the Sub Motor test
(page 4-42): Service Mode >
Engine Diag > Motor Test > Sub
Motor .
2. Does the Motor operate properly?
Go to step 23. Go to step 20.
20 1. Check the wiring harness
connectors P/J22 and P/J221
between the MCU Board and the
