Information:
System Operation Description:Use this procedure to troubleshoot the electrical system if a problem is suspected with the throttle actuator or if one of the diagnostic codes in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table
Description Conditions which Generate this Code System Response
1440-9 Throttle Actuator : Abnormal Update Rate The Electronic Control Module (ECM) has lost the last four messages that were expected from the throttle actuator over the CAN data link. The code is logged.
The alarm output is activated.
The shutdown output is activated.
The engine is shut down.
1440-12 Throttle Actuator : Failure The throttle actuator has reported that an internal fault has occurred. The throttle actuator is an electronic actuator that works with the master ECM in order to ensure the correct throttle position during all engine operating conditions.The master ECM is capable of modulating the throttle from a fully closed position to a fully opened position.CommunicationsThe master ECM and the throttle actuator communicate via the CAN data link. The master ECM sends a command signal to the actuator. The actuator sends the following information to the master ECM: actuator position, heartbeat signal, software version and internal fault diagnosis.If the ECM cannot communicate with the actuator, the ECM activates a 1440-9 diagnostic code and the engine is shut down. A 1440-9 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 or a problem with the power circuit for the actuator. The least likely cause is a problem with the ECM. After checking the power circuit for the actuator, refer to Troubleshooting, "CAN Data Link - Test" for information that is related to troubleshooting the 1440-9 diagnostic code.Self-diagnostic FunctionIf an internal fault is detected by the actuator, the condition is communicated via the CAN data link. The master ECM activates a 1440-12 diagnostic code and the engine is shutdown. The most likely cause of a 1440-12 diagnostic code is a problem with the actuator.

Set the engine control switch to the OFF/RESET position. Remove the electrical power from the engine.

Thoroughly inspect the harness connectors for the throttle actuator. Also, check the mechanical condition of the components of the throttle body. Check the full travel of the throttle plate and the throttle actuator. Ensure that the components are in good mechanical condition. Inspect the condition
