Schematic of the "Bowl Raise" solenoid
The CID 1275 diagnostic code is associated with the "Bowl Raise" solenoid. The solenoid is a part of the towed scraper. The FMI 05 means that the ECM has determined that an open in the circuit exists.The possible causes of this diagnostic code are listed below:
The circuit that energizes the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The ECM has failed. This condition is unlikely.Note: The following 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 CID 1275 FMI 05 diagnostic code is active before performing this procedure.Note: Use the digital multimeter of the measurements in this procedure.Test Step 1. CHECK THE SOLENOID
Turn the disconnect switch and the key start switch to the ON position. DO NOT start the engine.
Disconnect the solenoid with the active diagnostic code from the machine harness.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire J921-PK(Pink)) to contact 2 (wire H802-GY(Grey)).
Observe the status of the CID 1275 FMI 05 diagnostic code. Expected Result:The CID 1275 FMI 05 diagnostic code is no longer active. A CID 1275 FMI 06 diagnostic code becomes active when the jumper wire is connected.Results:
YES - The CID 1275 FMI 05 diagnostic code is no longer active. A CID 1275 FMI 06 diagnostic code becomes active when the jumper wire is connected. The solenoid has failed.Repair: Repeat this Test Step "CHECK THE SOLENOID" to verify the solenoid failure. Replace the solenoid. Verify that the new solenoid corrects the problem.STOP
NO - The CID 1275 FMI 05 diagnostic code remains active. The jumper wire does not affect the status of the diagnostic code. The solenoid is not causing the problem. Proceed to Test Step 2.Test Step 2. CHECK THE HARNESS FOR AN OPEN
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connectors from the ECM.
The jumper wire that was installed in the previous Test Step remains in place.
At the machine harness connector, measure the resistance from signal contact J1-58 (wire J921-PK(Pink)) to J1-60 (wire H802-GY(Grey)). Expected Result:The resistance is less than 5.0 ohms.Results:
OK - The resistance is less than 5.0 ohms. The machine harness is correct. Proceed to test step 4.
NOT OK - The resistance is greater than 5000 ohms. The resistance measurement is not correct. There is an open circuit in the machine harness.Repair: Check all of the connectors that are in the circuit. Ensure that all of the contacts for the circuit are in good condition, are clean, and are securely fastened in each of the harness connectors. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE OPERATION OF THE ECMThe disconnect switch and the key start switch remain in the OFF position. The machine harness connector for the solenoid and the Implement ECM J1 connector remain disconnected.
Remove the jumper wire that was installed in
