Information:
System Operation Description:Use this procedure to troubleshoot the following diagnostic codes:
1442-9 Fuel Actuator #1 abnormal update rate
1442-11 Fuel Actuator #1 other failure mode
1442-12 Fuel Actuator #1 failureThe fuel actuator is an electronic actuator that is controlled by the Electronic Control Module (ECM) in order to ensure the correct position of the fuel valve in all conditions of engine operation.The ECM and the fuel actuator communicate via the CAN data link. The ECM sends a command signal to the actuator. The actuator sends the following information to the ECM:
Actuator position
Heartbeat signal for the Customer Communication Module (CCM)
Software version
Internal fault diagnosisIf the ECM cannot communicate with the fuel actuator, the ECM activates a 1442-9 Fuel Actuator #1 abnormal update rate and the engine is shut down. A 1442-9 diagnostic code is probably caused by a problem with an electrical connector or a harness. The next likely cause is a problem with the actuator. The least likely cause is a problem with the ECM.Terminating resistors must be connected to each end of the CAN data link. The terminating resistors improve the communication between the devices. If there is an intermittent diagnostic code for any of the devices that are connected to the CAN data link, be sure to check the terminating resistors. One of the terminating resistors is connected to a splice in the wiring harness near the J1/P1 ECM connector. The other terminating resistor is connected to a "T" inside the optional remote panel. If the engine is not equipped with a remote panel, the other terminating resistor will be connected at the far end of interconnect harness. Refer to the appropriate documentation for the site in order to determine the location of this resistor.This troubleshooting procedure may generate additional diagnostic codes. Correct the cause of the original diagnostic code before continuing. You clear the diagnostic codes after the problem is resolved.

Schematic for the circuit for the fuel actuatorTest Step 1. Inspect the Electrical Connectors and the Wiring
Remove electrical power from the ECM. Set the engine control to the OFF/RESET mode.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
