Schematic of the Solenoid Valve (right forward steering) This diagnostic code is recorded when the ECM has determined that the solenoid has not responded in the proper manner.The possible causes of this diagnostic code are listed below:
The left forward steering has failed in the low pressure position.
The machine harness has failed.
The ECM has failed. This is unlikely.System Response:When this diagnostic code occurs, a warning is shown on the monitor. The diagnostic code will cause the transmission to shift to NEUTRAL. Limited operation at a reduced speed may be performed ONLY after you return the speed/direction control lever to the PARK position.Note: Ensure that the CID 0471 FMI 12 is on hold and that the diagnostic indicator shows "SERV CODE". The normal resistance of the coil at room temperature is 7.75 ohms. The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear these diagnostic codes when the original diagnostic code is corrected.Test Step 1. PERFORM THE TRACK SPEED CALIBRATIONS .
Turn the engine OFF.
Turn the key start switch to the ON position.
Use the Caterpillar Monitoring System to enter the calibration mode.
Enter Calibration Mode 5-13.
Hold down the "Clear" switch and the "Sensor/Speed Calibrate" Switch until the arrows that are shown on the main display module point in the up direction. This resets the calibrations for submodes 1 through 9, 15, 16, and 17.
Perform the calibration for submodes 1 through 9, 15, 16, and 17. Refer to the Testing and Adjusting, "Right and Left Pedal Calibration (Submode 1, Submode 2 Submode 5 and Submode 6)", the Testing and Adjusting, "Center Pedal Calibration (Submode 3 and Submode 4)", the Testing and Adjusting, "Speed and Direction Lever Calibration (Submode 7, Submode 8 and Submode 9)", and the Testing and Adjusting, "Track Speed Calibration (Submode 15, Submode 16 and Submode 17)".
Operate the machine.
Check the status of the diagnostic code of CID 0471 FMI 12.Expected Result:The diagnostic code of CID 0471 FMI 12 is not active.Results:
OK - The diagnostic code of CID 0471 FMI 12 is not active. The calibrations corrected the diagnostic code. resume normal operation. Stop.
NOT OK - The diagnostic code of CID 0471 FMI 12 is active. Proceed to Test Step 2.Test Step 2. CHECK FOR DIAGNOSTIC CODES THAT ARE RELATED TO THE OVERRIDE SOLENOID.
Turn the key start switch to the ON position.
Check for diagnostic codes that are related to the solenoid.The related diagnostic codes are listed below:
CID 0471 FMI 03
CID 0471 FMI 05
CID 0471 FMI 06Expected Result:There are no other diagnostic codes that are related to the solenoid.Results:
OK - There are no other diagnostic codes that are related to the solenoid. Proceed to Test Step E.
NOT OK - There are diagnostic codes that are related to the solenoid.Repair: Exit this procedure and perform the procedure for other related diagnostic codes. Stop.Test Step 3. CHECK THE CHARGE PRESSURE
Turn the key start switch to the OFF position.
Use a 3500 kPa (500 psi) gauge to verify that the charge pressure is set to 2850 100 kPa (413
