Step Actions and Questions
6 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?
Check the wiring harness connectors
7
P/J23, P/J232, and P/J2322 between
the MCU Board and the Registration
Sensor. Are the connectors securely
connected?
8 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
9
continuity.
1. Disconnect P/J23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
10 Check the Registration Sensor for
continuity.
1. Disconnect P/J23 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-8?
Check the Registration Sensor signal.
11
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?
