Step Actions and Questions
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.
8 Check the Right Side Harness for
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.
Check the Registration Sensor for
9
continuity.
1. Disconnect P/J29 from the MCU
Board.
2. Is there +3.3 V across ground <=>
J29-8 pin?
10 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?
Yes
