Information:
Illustration 1 g01159306This diagnostic code is associated with the Auto/Manual Switch for the right side of the Motor Grader. The FMI 03 means that the ECM has determined that the voltage of this circuit is above normal.The possible causes of this diagnostic code are listed:
The switch has failed.
The normally closed circuit of the switch is open.
The ground circuit of the switch is open.
The ECM has failed. This is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 2259 FMI 03 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this diagnostic code is active the hydraulic control system will default to the "Auto Not Allowed" state.Test Step 1. CHECK THE SWITCH
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector from the switch.
Use a Multimeter to verify the proper operation of the switch. Refer to Table 1 for the switch operation.
Table 1
Contacts A to B Contacts C to B Switch Status
Less than 5 ohms Greater than 5000 ohms Switch Not Pressed
Greater than 5000 ohms Less than 5 ohms Switch Pressed Expected Result:The switch is operating correctly.Results:
OK - The switch is operating correctly. Proceed to Test Step 2
NOT OK - The switch is not functioning correctly. There is an internal failure in the switch.Repair: Replace the switch.STOPTest Step 2. CHECK THE N/O AND N/C SWITCH CIRCUITS IN THE HARNESS
The key start switch and the disconnect switch remain in the OFF position.
Disconnect the machine harness connectors from the ECM. The switch remains disconnected.
At the connector for the switch place a jumper between contact A and C.
At the machine harness connector for the ECM, measure the resistance from contact "J1-40 (wire Y938-YL)" to contact "J1- 26 wire (J769-YL)". Expected Result:The resistance is less than 5 ohms.Results:
OK - The resistance is less than 5 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - The resistance is greater than 5000 ohms. The circuit is open.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE GROUND CIRCUIT OF THE SWITCH IN THE HARNESS
The key start switch and the disconnect switch Remain in the OFF position.
The machine harness connectors remains disconnected from the ECM and the switch.
Remove the jumper placed in the previous step.
At the connector for the switch place a jumper between contact a and c.
At the machine harness connector for the ECM, measure the resistance from contact "J1-56 (wire C209-BK)" to contact "J1- 26 wire (J769-YL)". Expected Result:The resistance is less than 5 ohms.Results:
OK - The resistance is less than 5 ohms. The machine harness is correct. Proceed to Test Step 4.
NOT OK - The resistance is greater than 5000 ohms. There is an circuit is open.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 4. CHECK IF THE DIAGNOSTIC CODE
