Offset Boom Right Solenoid connectionsThis diagnostic code is associated with the attachment Offset Boom Right Solenoid. The FMI 05 diagnostic code means that the Implement ECM 2 has determined that the circuit current for the solenoid is below normal.Note: The Offset Boom Right Solenoid is electrically connected to the Implement ECM 2. The condition of the solenoid is monitored by the Machine ECM. The Machine ECM monitors all components attached to the Implement ECM 2 via the CAN B data link.The Offset Boom Right Solenoid is a proportional solenoid. The solenoid is controlled by the Implement ECM 2 through a PWM driver output. The Implement ECM 2 will control the current to the solenoid depending on the position of the thumbwheel on the right-hand joystick. This solenoid can be overridden in Cat ET.Conditions that could cause this diagnostic code are listed below:
The solenoid has failed.
The energize circuit of the solenoid is open or has a poor connection.
The return circuit of the solenoid is open.
The ECM has failed. This situation is unlikely.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 these diagnostic codes when the original diagnostic code has been corrected.Test Step 1. CHECK THE SOLENOID
Disconnect the solenoid from the machine harness.
At the machine harness connector for the solenoid, connect a jumper wire from contact 1 (wire K762-BU) to contact 2 (wire H864-GN).
Turn the disconnect switch and the key switch to the ON position. Do not start the engine.
Observe the status of the CID 2545 FMI 05 diagnostic code.Expected Result:The diagnostic code changes from an FMI "05" to an FMI "06" diagnostic code as the jumper wire is installed.Results:
YES - The diagnostic code changes from an FMI "05" to an FMI "06" diagnostic code when the jumper wire is installed. 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. Verify that the new solenoid corrects the problem.STOP
NO - The CID 2545 FMI 05 diagnostic code remains active. The jumper wire does not affect the status of the diagnostic code. The solenoid is not the cause of the problem. Proceed to Test Step 2.Test Step 2. CHECK THE CIRCUIT FOR AN OPEN
Turn the key switch and the disconnect switch to the OFF position.
The jumper wire that was installed in the previous test step remains in place.
Disconnect the machine harness ECM connector from the Implement ECM 2.
At the machine harness connector for the Implement ECM 2, measure the resistance from the supply contact Pin 32 (wire K762-BU) to the return contact Pin
