Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the surface of the CTD Sensor for
contamination and foreign substances.
Is there any contamination or foreign substances
on the Sensor surface of the
Left/ Right CTD
Sensor section that comprise the CTD Sensor
Assembly?
Clean and remove any
debris on the Sensor
surface of the Left/
Right CTD Sensor.
Go to step 2.
2. Check the installation of the CTD Sensor
Assembly (REP 9.9 CTD Sensor Assembly on
page 4-175).
Is the CTD Sensor Assembly installed properly?
Go to step 3. Reinstall the CTD
Sensor Assembly.
3. Check the connection between the CTD Sensor
Assembly and MCU PWB.
Are the connectors P/J4571, P/J4572, and
P/J4561 connected securely?
Go to step 4. Connect the
connectors P/J4571,
P/J4572, and P/J4561.
4. Check the conductivity between the CTD Sensor
Assembly and MCU PWB.
Are the connections between P/J4571 <=>
P/J457, between P/J4572 <=> P/J457, and
between P/J4561 <=> P/J456 conducting
properly?
Go to step 5. Replace the Main CTD
Harness Assembly.
