Schematic of the "Swing Brake Solenoid" circuitThis diagnostic code is associated with the "swing brake" solenoid.This diagnostic code is recorded when the ECM reads the current of the solenoid as being above normal.The possible causes are listed below:
A wire is shorted to ground.
The solenoid has failed.
The ECM has failed. A failure of the ECM is unlikely.Note: The Machine ECM is equipped with LED indicators that serve as a self-diagnostic check. With the key start switch in the ON position, the following can be determined by the ECM indicator lights:
If all of the LED lights are OFF, voltage is not being supplied to the Machine ECM. Check for power to the ECM.
If the yellow LED is Flashing, a communication error exists on the "CAN" data-link circuit.
If the yellow LED is constantly ON, the Machine ECM software may be missing / not loaded.
If the red LED is Flashing, the Machine ECM has failed and may need replacement. Note: The following procedure can create numerous related diagnostic codes. When all harnesses are reconnected, the related diagnostic codes will be shown as being not active. Clear all related diagnostic codes after this procedure is completed.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 machine harness from the solenoid.
Observe the status of the diagnostic code.
Install a jumper wire between contacts 1 and 2 of the machine harness connector.
Observe the diagnostic code.Expected Result:The diagnostic code is active. Then, the diagnostic code changes to an FMI 05 diagnostic code as the jumper wire is installed.Results:
NO - The circuits are correct. The solenoid has failed.Repair: Repeat this test "CHECK THE SOLENOID" in order to verify that the solenoid has failed. Replace the solenoid.STOP
YES - The diagnostic code remains active. Proceed to Test Step 2.Test Step 2. CHECK THE SOLENOID CIRCUIT FOR A SHORT TO GROUND.
The machine harness remains disconnected from the solenoid.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the J1 and J2 machine harness connector from the Machine ECM.
At the J2 machine harness connector, measure the resistance from the solenoid contact J2-23 (wire K907-BU) to all possible sources of ground. Expected Result:Each resistance measurement should be greater than 5000 ohms.Results:
YES - The machine harness is correct. Proceed to Test Step 3.
NO - There is a short in the machine harness.Repair: The short is between the wire for the solenoid signal and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts of the harness connector. Clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Stop the machine and place the parking brake switch in the ON position.
Check if the diagnostic code for the solenoid is active.Expected Result:The diagnostic code is no longer active. Results:
YES - The diagnostic code is no
