Sensor.
2. Does the number on the Control
Panel increase by 1 when the
Actuator of the Registration Sensor
is activated?
1. Check the wiring harness
6
connectors P/J29, P/J292, and P/
J2922 between the MCU Board and
the Registration Sensor.
2. Are the connectors securely
connected?
7
Check the Registration Sensor
Harness for continuity.
1. Disconnect P/J292 from the Right
Side Harness and P/J2922 from the
Regi Sensor.
2. Check continuity between P/J292
<=> P/J2922.
Check the Right Side Harness for
8
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.
9
Check the Registration Sensor signal.
1. Disconnect P/J29 from the MCU
Board.
2. Is there +3.3 V across ground <=>
J29-8 pin on the MCU Board?
10
Check the Registration Sensor for
signal.
1. Measure the voltage across ground
<=> J29-10 pin on the MCU Board.
2. Does the voltage change when the
