Replace the
Right Side
Harness.
6
Check the Registration Sensor for
continuity.
1. Disconnect P/J29 from the MCU
Board.
2. Is there +3.3 V across ground <=>
J29-8 pin?
Go to step 7.
Replace the
MCU Board
(page 8-86).
7
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?
Replace the
MCU Board
(page 8-86).
Replace the
Regi Sensor
(page 8-43).
