CDL Diagnostic
Sensor Description DTC CID FMI Harness Pin Number Harness Connector
Fuel Supply Flow Rotor Speed Sensor 1 4515 10 and 14 J1-6 A-C2

Fuel Return Flow Rotor Speed Sensor 1 4517 10 and 14 J1-61 C-C2
Fuel Return Flow Rotor Speed Sensor 2 4518 8 J1-63 C-C3 If the fuel volume speed sensor detects an abnormal rate of change, a diagnostic of FMI 10, "Abnormal Rate of Change", will be reported on the SAE J1939 data link and the CDL data link for the errant sensor. An "Abnormal Rate of Change" will be detected when the measured frequency is greater than the maximum flow rate for which the transducer is rated.If the fuel volume speed sensor detects an abnormal frequency, pulse width or period, a diagnostic of FMI 8, "Abnormal Frequency, Pulse Width or Period", will be reported on the SAE J1939 data link and the CDL data link for the errant sensor. This indicates a loose or pinched wire or an errant speed sensor. An abnormal frequency, pulse width, or period will be detected if the frequency reading indicates that the transducer has been installed backwards.If the fuel volume speed sensor outputs a flow rate of 160 pps or more, a diagnostic with FMI 14 will be reported on the SAE J1939 data link and the CDL. This indicates that the flow rate through the transducer is approaching the maximum flow rate.Temperature Sensor Diagnostic Indicators
If a temperature sensor fails, the ECM raises a diagnostic message and sends it on the main SAE J1939 data link and the CDL bus.
Table 16
Sensor Description SAE J1939 SPN CDL DTC CID Harness Pin Number Harness Connector
Fuel Flow Supply Temperature Sensor 2775 4519 J1-36 A-C4
Fuel Flow Supply Temperature Sensor 2776 1929 J1-37 C-C4 If a diagnostic of FMI 3, Voltage Above Normal, is reported on the SAE J1939 data link or the CDL data link for the errant sensor, this indicates possible short to battery indicating a broken wire or defective sensor.If a diagnostic of FMI 4, Voltage Below Normal, is reported on the SAE J1939 data link or the CDL data link for the errant sensor, this indicates possible short to ground indicating a pinched wire or defective sensor.Data Retention
The system is designed to monitor the fuel consumed by the engine, irrespective of time. If either transducer is replaced, the ECM will not reset the fuel volume values.Replacing Failed Parts
The fuel volume transducer is a precision device. If the transducer experiences a failure in one of the sensors, the specific sensor can be replaced without impacting the calibration of the device.Replacement part numbers are as follows:
