Schematic for the Modulating Valve for Speed 3 (Number 3)
This diagnostic code is for the Modulating Valve for Speed 3 (Number 3).See Systems Operation, "Solenoid Valves" for help with the identification of the locations of the solenoids.This diagnostic code is recorded when there is a speed difference between two transmission components. System Response:The components of the transmission should be locked by the clutch that corresponds to the recorded CID. Test Step 1. CHECK FOR OTHER RECORDED DIAGNOSTIC CODES.
View the log of the diagnostic codes. Check for recently logged diagnostic codes for speed sensors. Expected Result:There are other diagnostic codes that are active, or there are recently logged diagnostic codes for speed sensors.Results:
YES - There are other diagnostic codes that are active, or there are recently logged diagnostic codes for speed sensors.Repair: Other diagnostic codes may indicate the reason for the speed difference between the transmission components that corresponds to the diagnostic codes. Exit this test procedure and perform the procedure for the diagnostic codes that are active or logged. The diagnostic codes for the speed sensor are listed: CID 0671 FMI 02, CID 0672 FMI 02, CID 0673 FMI 02, CID 0674 FMI 02 and CID 0675 FMI 02. Operate the machine. If the CID 0693 FMI 07 is still present, return to the test procedure for CID 0693 FMI 07.STOP
NO - There are not other diagnostic codes that are active. Proceed to Test Step 2.Test Step 2. CHECK THE SUPPLY PRESSURE.
Check the supply pressure to the transmission modulating valves. Refer to the Testing and Adjusting manual for the power train of the machine that is being serviced. Expected Result:The supply pressure to the transmission modulating valves is correct.Results:
YES - The supply pressure to the transmission modulating valves is correct. Proceed to Test Step 4.
NO - The supply pressure to the transmission modulating valves is not correct. Proceed to Test Step 3.Test Step 3. RECHECK THE SUPPLY PRESSURE.
Repair the cause of the incorrect supply pressure to the transmission modulating valves. Refer to the Testing and Adjusting manual for the power train of the machine that is being serviced.
Operate the machine.
Stop the machine and place the parking brake switch in the ON position.
Determine if CID 0693 FMI 07 is present. Expected Result:CID 0693 FMI 07 is present.Results:
YES - CID 0693 FMI 07 is present. Proceed to Test Step 4.
NO - CID 0693 FMI 07 is not present.Repair: Resume normal machine operation.STOPTest Step 4. CHECK THE CLUTCH PRESSURE.
Check the pressure to the reverse clutch. Refer to the Testing and Adjusting manual for the power train of the machine that is being serviced. Expected Result:The pressure for the reverse clutch is correct when the machine is in forward or reverse.Results:
YES - The pressure for the reverse clutch is correct when the machine is in forward or reverse. Proceed to Test Step 6.
NO - The pressure for the reverse clutch is not correct when the machine is in forward or reverse. The pressure for the reverse clutch is incorrect. Proceed to
