Schematic for the speed control circuit (typical example)Test Step 1. Inspect the Electrical Connectors and the Wiring
Remove electrical power from the ECM.
Thoroughly inspect the engine interface connector and the J1/P1 ECM connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details that are related to inspection of the electrical connectors.

Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the engine interface connector that are associated with the circuit.
Check the allen head screw on each ECM connector and the engine interface connector for the proper torque. refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect" 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, and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The connectors and wiring appear to be 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 Status for "Throttle Position"
Connect Caterpillar Electronic Technician (ET) to the service tool connector.
Restore electrical power to the ECM.
Observe the status for "Throttle Position" on Cat ET while you operate the throttle through the entire range of travel.
Remove electrical power from the ECM.Expected Result:The status is zero percent when the throttle is in the lowest position of travel. The status progressively increases to 100 percent when the throttle is in the highest position of travel.Results:
OK - The throttle position sensor is working properly.Repair: There may be an intermittent electrical problem with the harness or the connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect" if an intermittent electrical problem is suspected.STOP
Not OK - The throttle position that is displayed on Cat ET does not correspond to the movement of the throttle. Proceed to Test Step 3.Test Step 3. Check the Supply Voltage at the Sensor
Disconnect the throttle position sensor at the harness connector.
Restore electrical power to the ECM.
Measure the voltage across terminal A (+Battery) and terminal B (−Battery) on the harness side of the connector.
Remove electrical power from the ECM. Restore the wiring to the original configuration.Expected Result:The supply voltage measures 24 2 VDC at the sensor connector for 24 V systems. The supply voltage measures 12 2 VDC at the sensor connector for 12 V systems.Results:
OK - The correct voltage is measured at the sensor connector. The sensor is receiving the correct supply voltage. Proceed to Test Step 4.
Not OK - The voltage is not correct at the sensor
