Section 5.28
PID 110, FMI 4, Flash Code 15, the Coolant Temperature Sensor Input Voltage Low
The Coolant Temperature Sensor (CTS) input voltage is low due to a short.
Section 5.28.1
Troubleshooting PID 110, FMI 4, FLASH CODE 15
Troubleshoot as follows:
NOTICE: |
To avoid damage to the harness and connectors when disconnecting harness connectors, ensure the pulling force is applied to the connectors and not to the wires extending from the connectors. |
- Check wire 133 (yellow, coolant temperature) cavity P-3 in the Engine Sensor Harness (ESH) 30–pin connector for a short to ground (see Figure
"Engine Sensor Harness 30–pin Connector"
). If there is a short, repair or replace any open wire(s).

- If the code is still active, go to step .
- If the code is no longer active, refer to "5.28.2 Verification" .
- Check pin B (coolant temperature) in the Coolant Temperature Sensor connector for a short. If there is a short, repair or replace any open wire(s).
- If the code is still active, call Detroit Diesel Technical Support.
- If the code is no longer active, refer to "5.28.2 Verification" .
Section 5.28.2
Verification
Verify troubleshooting as follows:
- Check the DDR to see if PID 110, FMI 4, Flash Code 15 is still active.
- If the code is still active, go to step 2.
- If the code is not active, troubleshooting is complete.
- If the code is still active, call Detroit Diesel Technical Service.
