Troubleshooting Procedure
Step Actions and Questions Yes No
1. 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 2. Reinstall the CTD
Sensor Assembly.
2. Check the connection between the CTD Sensor
Assembly and MCU PWB.
Is the connector P/J4561 connected securely?
Go to step 3. Connect the connector
P/J4561.
3. Check the conductivity between the CTD Sensor
Assembly and MCU PWB.
Is the connection between P/J4561 <=> P/J456
conducting properly?
Go to step 4. Replace the Main CTD
Harness Assembly.
4. Check the connection in the CTD Sensor
Assembly.
Is the connector P/J4563 connected securely?
Go to step 5. Connect the connector
P/J4563.
5. Replace the CTD Sensor Assembly (REP 9.9 CTD
Sensor Assembly on page 4-175).
Does the error persist?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
