Sensor Troubleshooting Procedure (S1, S2, S3, S4, S5, S16, S43, and
S45):
1. Do GP 6.3.2 SENSORS Procedure. Check to make sure the sensor
shows "0" on the LCD when uncovered and "1" when covered.
If the sensor shows "1" when uncovered, clean the sensor. Also
check if there is any obstacle in the sensor window.
All sensors show "0" when uncovered and "1" when covered
Yes- Return to the RAP that directed you here.
No- Go to Step 2
2. Make sure the sensor wire is connected securely at the Sensor and at
the Main Control Board (PL 5.27). Do REP 1.5 to remove the Rear
Cover to gain access to the connector at the Control Board. Refer
to GP 6.22 and Section 7 for additional info regarding the connector
locations.
All the connections are made securely
Yes- Go to Step 3
No- Make the connection and repeat Step 1.
3. Replace the Sensor with a new one (alternatively, swap the sensor in
the faulty position with a sensor from a different good position to
check if it is a bad sensor).
Replacing the sensor corrects the issue
Yes- Install the new sensor and return to normal operation
No- Go to Step 4
4. Visually inspect the Cable from the sensor all the way to the Control
Board (PL 5.27). If the Cable is damaged, replace the Cable. Refer
to GP 6.22 to identify all cables used with the sensor.
Sensor cable looks okay
Yes- Go to Step 5
No- Go to Step 6
