Schematic of the "Brake Cooling Pump" solenoid
This diagnostic code is associated with the "Brake Cooling Pump" solenoid. The FMI 06 diagnostic code means that the ECM has determined that the current for the solenoid is above normal. There may be a short to ground in the solenoid circuit. Some possible causes of this diagnostic code are listed below:
The energize circuit of the solenoid is shorted to ground.
The solenoid has failed.
The Brake ECM has failed. This situation is unlikely.System Response:When the CID 1230 FMI 06 diagnostic code is active, the machine response will be:
The rear axle cooling fan will not operate correctly.
The coolant temperature may increase.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. Ensure that the diagnostic code of CID 1230 FMI 06 is active before performing 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.
Observe the status of the diagnostic code.
Disconnect the solenoid with the active diagnostic code from the machine harness. Expected Result:The CID 1230 FMI 06 diagnostic code changes to a CID 1230 FMI 05 diagnostic code when the solenoid is disconnected.Results:
YES - The CID 1230 FMI 06 diagnostic code changes to a CID 1230 FMI 05 diagnostic code when the solenoid is disconnected. The circuit is correct.Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID" to verify the solenoid failure. Replace the solenoid.STOP
NO - The CID 1230 FMI 06 diagnostic code remains active. Proceed to Test Step 2.Test Step 2. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO GROUND
Turn the key start switch and the disconnect switch to the OFF position.
The solenoid remains disconnected from the machine harness.
Disconnect the machine harness connectors J1 and J2 from the Brake ECM.
At the machine harness connectors, measure the resistance from the signal contact J1-49 (wire J817-WH(White)) to frame ground or to a ground contact on connectors J1 or J2. Expected Result:The resistance measurement is greater than 5000 ohms.Results:
OK - The resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - The resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between J1-49 (wire J817-WH(White)) and one of the grounded wires in the machine harness. Repair: Repair or replace the machine harness. STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS
Inspect the contacts of the harness connectors that are used in the solenoid circuit. Ensure that the contacts are secure. Clean all of the contacts in 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 1230 FMI 06 diagnostic code. Expected Result:The CID 1230 FMI 06 diagnostic code is still active. Results:
YES - The CID 1230 FMI 06 diagnostic code is still
