Step Actions and Questions
5 Perform the Registration Sensor test
(page 4-29): Service Mode
Diag > Sensor Test
Does the number on the Control Panel
increase by 1 when the Actuator of the
Registration Sensor is activated?
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?
Check the Registration Sensor
7
Harness for continuity.
1. Disconnect P/J232 and P/J2322.
2. Check continuity between P/J232
<=> P/J2322.
Check the Right Side Harness for
8
continuity.
1. Disconnect P/J23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
Check the Registration Sensor signal.
9
1. Disconnect P/J23 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-8?
Check the Registration Sensor for
10
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?
11 Perform the Tray 2 Motor test
(page 4-42): Service Mode
Diag > Motor Test
Does the Motor operate?
Check the wiring harness connectors
12
P/J25 and P/J251 between the MCU
Board and the Tray 2 Motor. Are the
connectors securely connected?
Check the Right Side Harness for
13
continuity.
1. Disconnect P/J25 and P/J251.
2. Check continuity between P/J25 <=>
P/J251.
