This diagnostic code is associated with the Right Grade Offset Switch that is used for setting the offset for the right end of the blade. The FMI 03 means that the ECM has determined that the voltage of the switch circuit is above normal.The possible causes of this diagnostic code are listed:
The switch has failed.
The switch is shorted to the +battery circuit.
The ECM has failed. This is unlikely.Note: Ensure that the diagnostic code of CID 2262 FMI 03 is active before performing this procedure.Test Step 1. CHECK THE OPERATION OF THE SWITCH.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector from the Switch.
Table 1
Contacts    Switch State    
Increment Neutral    Decrement    
Contacts 1 to 2     Greater than 5000 ohms     Greater than 5000 ohms     Less than 5 ohms    
Contacts 2 to 3     Less than 5 ohms     Greater than 5000 ohms     Greater than 5000 ohms    
Contacts 2 to 4     Greater than 5000 ohms     Less than 5 ohms     Greater than 5000 ohms    
Measure the resistance between the contact points on the connector listed in the table above. Note the resistance values.Expected Result:The measurements agree with the values that are listed in Table 1.Results:
YES - The resistances that were measured agree with the expected measurements listed in the table. Proceed to Test Step 2.
NO - The resistance measurements do not reflect the expected measurements that are listed in the table. The switch has failed.Repair: Replace the switch.STOPTest Step 2. CHECK FOR A SHORTED HARNESS.
The Right Grade Offset Switch remains disconnected.
Turn the disconnect switch and the key start switch to the OFF position.
Disconnect the harness connector (J1) from the ECM.
At the harness connector for the ECM (J1), measure the resistance between contact J1-34 (wire K722-YL) and ALL other J1 connector contacts.
At the harness connector for the ECM (J1), measure the resistance between contact J1-35 (wire K723-PU) and ALL other J1 connector contacts.
At the harness connector for the ECM (J1), measure the resistance between contact J1-40 (wire Y935-OR) and ALL other J1 connector contacts.
At the harness connector for the ECM (J1), measure the resistance between contact J1-56 (wire C209-BK) and ALL other J1 connector contacts.Expected Result:The resistance is greater than 5000 Ohms.Results:
YES - The resistance is greater than 5000 Ohms. The harness resistance is correct. Proceed to Test Step 3.
NO - Resistance is less than 5000 Ohms. Repair: The harness has failed. Repair the harness or replace the harness.STOPTest Step 3. CHECK FOR AN OPEN HARNESS.
The Right Grade Offset Switch remains disconnected from the harness.
The key start switch and the disconnect switch are in the OFF position.
At the harness connector for the Right Grade Offset Switch, place a jumper wire between the following contacts:
Contact 1 (wire K722-YL) and Contact 2 (wire C209-BK)
Contact 3 (wire K723-PU) and contact 4 (wire Y935-OR)
The J1 connectors remain disconnected from the ECM.
At the harness connector for the ECM, measure the resistance between contact J1-34 (wire K722-YL)
