Information:
System Operation Description:Perform this procedure if the "Direct Fuel Control Mode" is "ON" and a 91-08 Throttle Position Signal Abnormal diagnostic code is active.The direct fuel control mode enables the engine to be controlled by an external governor. You must install the components of the signal converter for the direct fuel control in order to operate in direct fuel control mode. The configuration parameter must be programmed to "ON" in order for the Electronic Control Module (ECM) to respond properly to the external governor.The input to the signal converter is a 0 to 200 mA signal. The signal is received from the external governor. The output signal from the signal converter is a Pulse Width Modulated signal (PWM).The output signal varies with the current to the signal converter. The ECM calculates the desired fuel from the PWM signal.The duty cycle for a valid signal is between 5 and 95 percent. If an invalid signal is received, the engine will automatically be set to a minimum fuel setting and the engine will shut down.The following functions are not used in direct fuel control mode.
Low idle
Crank terminate speed
Cooldown speed

Typical example
Test Step 1. Check for Connector Damage
Turn the Engine Control Switch (ECS) to the OFF/RESET position.
Turn the battery disconnect switch to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the allen head screw on each ECM connector for the proper torque. Refer to Troubleshooting, "Inspecting Electrical Connectors" for the correct torque values.
Check the harness and the wiring for abrasion and for pinch points. Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check the Current Input to the Signal Converter
Measure the current to the signal converter. Note: Some external governors may only be able to output approximately 150 mA. This should not be seen as a problem with the external governor.Expected Result:The current range is between 0 and 200 mA.Results:
OK - The current is within the correct range. Proceed to Test Step 3.
Not OK - The current is not within the correct range.Repair: Replace the external governor that is supplying the controlling current.STOPTest Step 3. Check the Voltage at the Battery
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Measure no-load battery voltage at the battery terminals. Refer to Testing and Adjusting, "Test Tools for the Electrical System" for the proper procedures to check the batteries.
Load test the batteries. Use the 4C-4911 Battery Load Tester. Refer to the Operating Manual,
