Step Actions and Questions
8 Check the Exit Sensor for signal.
1. Measure the voltage across ground
<=> P/J17-3.
2. Does the voltage change when the
Actuator of the Exit Sensor is
activated?
Perform the Registration Sensor test
9
(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?
10 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?
11 Check the Registration Sensor
Harness for continuity.
1. Disconnect P/J232 and P/J2322.
2. Check continuity between P/J232
<=> P/J2322.
Check the Right Side Harness for
12
continuity.
1. Disconnect P/J23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
Check the Registration Sensor for
13
continuity.
1. Disconnect P/J23 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-8?
Check the Registration Sensor signal.
14
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?
15 Perform the Main Motor test
(page 4-40): Service Mode
Diag > Motor Test
Does the Motor operate properly?
Check the wiring harness connectors
16
P/J21 and P/J211 between the MCU
Board and the Main Drive. Are the
connectors securely connected?
