Schematic of the "Stick In" SolenoidThis diagnostic code is associated with the solenoid of the Stick In solenoid. The FMI 03 diagnostic code indicates that the Machine ECM is detecting a voltage for the solenoid that is above normal. Conditions that can cause this diagnostic code to be activated are listed below:
There is a problem with the power supply for the solenoid.
The signal circuit for the solenoid has an open or a bad connection.
The signal circuit for the solenoid is shorted to a voltage source.
The solenoid has failed.
The ECM has failed. A failure of the Machine ECM is unlikely.Note: When this diagnostic code is activated, verify that there are no other active diagnostic codes for the solenoid. The active diagnostic code for the solenoid must be cleared before proceeding with this procedure.Note: Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure and in good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected.Test Step 1. CHECK THE POWER SUPPLY OF THE SOLENOID
Turn the key start switch and the disconnect switch to the ON position.
Disconnect the machine harness connector from the sensor.
At the machine harness connector for the sensor, measure the supply voltage between the contact of the power supply (wire P943-GY) and the ground contact (wire K869-BU).Expected Result:The measurement of the supply voltage is 5.0 0.3 VDC.Results:
OK - The voltage measurement is approximately 5.0 0.3 VDC. The power supply for the sensor is correct. Proceed to Test Step 2.
NOT OK - The voltage measurement is less than 5.0 0.3 VDC. The power supply for the sensor is not correct. Repair: Either the return circuit K869-BU or the supply circuit P943-GY has a bad connection or an open in the machine harness. Examine all of the connectors that are in the circuit. Ensure that the connections are clean, secure, and in good condition. Refer to the CID 0262 diagnostic code procedures in this manual for troubleshooting of the power supply. Correct the problem with the ECM power supply. After the power supply is correct, verify that this diagnostic code is still active before proceeding with this procedure.STOPTest Step 2. CHECK FOR AN OPEN IN THE SENSOR CIRCUITThe machine harness connector remains disconnected from the sensor.
Turn the key start switch and the disconnect switch to the OFF position.
At the machine harness connector for the sensor, place a jumper wire between the return contact of the solenoid (wire K869-BU) and the signal contact (wire P943-GY) .
Disconnect machine harness connectors J1 and J2 from the ECM.
At the harness connectors for the ECM, measure the resistance from
