Schematic of the Primary Steering pressure switch
This diagnostic code is associated with the Primary Steering pressure switch. An FMI 03 means the ECM has determined the voltage on the Primary Steering pressure switch circuit is above normal. Possible causes of this diagnostic code are:
Both contacts are open at the same time.
One contact is shorted to a voltage source.Note: The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 0793 FMI 03 is active before performing this procedure.Test Step 1. CHECK THE GROUND CIRCUIT OF THE SWITCH IN THE HARNESS.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the J1 and J2 harness connectors from the machine ECM.
Measure the resistance between contact J1-13 (wire 202-BK(Black)) of the machine harness for the ECM and contact A (wire 202-BK(Black)) at the switch. Expected Result:The resistance is less than 5 ohms. Results:
YES - The resistance is less than 5 ohms. The circuit is correct. Go to Test Step 2.
NO - The resistance is greater than 5000 ohms. The circuit is open. The machine harness has failed.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE SWITCH CIRCUITS FOR A SHORT TO THE +BATTERY CIRCUIT.
The J1 and J2 harness connectors remain disconnected from the ECM.
The disconnect switch and the key start switch remain in the OFF position.
Disconnect contact B (wire 417-GY(Grey)) and contact C (wire 484-YL(Yellow)) from the connector of the switch.
At the machine harness connector for the ECM, measure the resistance from contact B (wire 417 J2-37-GY(Grey)) and contact C (wire 484-YL(Yellow)) of the machine harness to all the contacts that are used in the machine harness connectors for the ECM. Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
YES - Each resistance measurement is greater than 5000 ohms. The harness is correct. Go to Test Step 3.
NO - One or more of the measurements were less than 5 ohms. There is a short in the machine harness. Repair: The short is between wire 417-GY(Grey) and the circuit with the lowest resistance measurement or the short is between wire 484-YL(Yellow) and the circuit with the lowest resistance measurement. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE SWITCH CIRCUITS IN THE HARNESS.
The J1 and J2 harness connectors remain disconnected from the ECM and the switch.
At the harness connector for the switch, connect a jumper wire between contact B (wire 417-GY(Grey)) and contact C (wire 484-YL(Yellow)).
At the harness connector for the ECM, measure the resistance from contact J2-37 (wire 417-GY(Grey)) to contact J2-38 (wire 484-YL(Yellow)). Expected Result:The resistance is less than 5 ohms. Results:
YES - The resistance is less than 5 ohms. Go to Test Step 4.
NO - The resistance is greater than 5000 ohms. The circuit is open.Repair: The machine harness has failed. Repair the machine harness or replace the machine harness.STOPTest Step 4. CHECK THE
