Schematic of the Left Stabilizer Cylinder Extend Solenoid | |
This diagnostic code is associated with the Left Stabilizer Cylinder Extend Solenoid. FMI 05 indicates that the ECM has detected that an open exists in the circuit of the Left Stabilizer Cylinder Extend Solenoid.
The possible causes of this diagnostic code are listed below:
- The energize circuit of the solenoid is open.
- The return circuit of the solenoid is open.
- The solenoid has failed.
- A relay has failed.
- The stabilizer switch has failed.
- The ECM has failed. This is unlikely.
Note: The following test procedure may create other diagnostic codes. Ignore these codes until the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 2287 FMI 05 is active before performing this procedure.
Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.
System Response:
The left stabilizer cylinder extend control will be disabled until the diagnostic has been corrected.
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 Left Stabilizer Cylinder Extend Solenoid from the machine harness.
- At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire 776-YL) to contact 2 (wire 784-YL).
- Observe the status of the CID 2287 FMI 05.
Expected Result:
The CID 2287 FMI 05 remains active.
Results:
- YES - The diagnostic code remains active. The jumper wire does not affect the diagnostic code. Proceed to Test Step 2.
- NO - The diagnostic is no longer active. The solenoid has failed.
Repair: The solenoid has failed. Repeat this Test Step "CHECK THE SOLENOID" in order to verify the solenoid failure. Replace the solenoid and verify that the new solenoid corrects the problem.
STOP
Test Step 2. CHECK THE HARNESS FOR AN OPEN.
- Turn the key start switch and the disconnect switch to the OFF position.
- Disconnect the connector from the Left Stabilizer Switch.
- The jumper wire that was installed in the previous Test Step remains in place.
- At the Left Stabilizer Switch connector, measure the resistance from switch connector contact 1 (wire 784-YL) to switch connector contact 4 (wire 776-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 resistance measurement is not correct. There is an open circuit in the machine harness.
Repair: Repair or replace the machine harness, as required. The open circuit is in wire 776-YL or in wire 784-YL of the machine harness.
STOP
Test Step 3. CHECK THE RELAYS.
- Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
- Disconnect the Stabilizer Relay 1 or Stabilizer Relay 2 from the machine harness, as required.
- At the machine harness connector for Stabilizer Relay 1, install a jumper wire between contact F1 (wire C903-BU) and contact F2 (wire 116-BR) and for the Stabilizer Relay 2, install a jumper wire between contact A1 (wire C905-OR) and contact A2 (wire 116-BR).
- Observe the status of the CID 2287 FMI 05.
Expected Result:
The CID 2287 FMI 05 remains active.
Results:
- YES - The diagnostic code remains active. The jumper wires do not affect the diagnostic code. Proceed to Test Step 4.
- NO - The diagnostic is no longer active. A relay has failed.
Repair: A relay has failed. Repeat this Test Step "CHECK THE RELAYS" in order to verify the failure of the relay. Replace the failed relay and verify that the new relay corrects the problem.
STOP
Test Step 4. CHECK THE SWITCH.
- Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
- Disconnect the LH Stabilizer Switch from the machine harness.
- At the machine harness connector for the switch, install a jumper wire between contact 2 (wire J759-GN) and contact 1 (wire 784-YL). Install a jumper wire between contact 5 (wire J757-PU) and contact 4 (wire 776-YL).
- Observe the status of the CID 2287 FMI 05.
Expected Result:
The CID 2287 FMI 05 remains active.
Results:
- YES - The diagnostic code remains active. The jumper wires do not affect the diagnostic code. Proceed to Test Step 5.
- NO - The diagnostic is no longer active. The switch has failed.
Repair: The switch has failed. Repeat this Test Step "CHECK THE SWITCH" in order to verify the failure of the switch. Replace the switch and verify that the new switch corrects the problem.
STOP
Test Step 5. CHECK IF THE DIAGNOSTIC CODE REMAINS.
- Inspect the contacts of the harness connectors and clean the harness connectors.
- Reconnect all harness connectors.
- Turn the disconnect switch and the key start switch to the ON position.
- Operate the machine.
- Check the status of the CID 2287 FMI 05.
Expected Result:
The CID 2287 FMI 05 is active.
Results:
- YES - The CID 2287 FMI 05 is active. The diagnostic code has not been corrected. The ECM may have failed.
Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. If the cause of the diagnostic code is not found, replace the ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
STOP
- NO - The CID 2287 FMI 05 is not active. The diagnostic code does not exist at this time.
Repair: The initial diagnostic code was probably caused by a poor electrical connection at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.
