Schematic of the "Priority Solenoid" valve
The CID 0697 diagnostic code is associated with the priority valve solenoid. The FMI 06 diagnostic code is recorded when the current of the solenoid circuit is above normal.Note: The following 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 CID 0697 FMI 06 diagnostic code is active before performing this procedure.System Response:The low-pressure pump will remain at a high pressure. Some horsepower will be lost during the times when increased high-pressure flow is not necessary.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 active CID 0697 FMI 06 diagnostic code changes to a CID 0697 FMI 05 diagnostic code.Results:
OK - The active CID 0697 FMI 06 diagnostic code changes to a CID 0697 FMI 05 diagnostic code. The circuit is correct.Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID" to verify the solenoid failure. Replace the solenoid. Calibrate the solenoid for the "bladelower" function. Refer to Testing and Adjusting, "Calibration" procedure in the service manual for your machine.STOP
NOT OK - The CID 0697 FMI 06 diagnostic code remains active. The solenoid is not causing the problem. Proceed to test step 2.Test Step 2. CHECK THE SIGNAL CIRCUIT OF THE SOLENOID FOR SHORT TO GROUND.
Turn the key start switch to the OFF position. The machine harness remains disconnected from the solenoid.
Disconnect the J1 and J2 machine harness connectors from the ECM.
At machine harness connector J1 or J2, measure the resistance from the J1-12 (solenoid signal) to all possible sources of ground. Expected Result: Each resistance should be greater than 5000 ohms.Results:
OK - The machine harness is correct. Proceed to test step 3.
NOT OK - There is a short in the machine harness. The harness has failed.Repair: The short is between wire K978-BU(Blue) and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE STATUS OF THE DIAGNOSTIC CODE
Inspect the contacts and 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 CID 0697 FMI 06 diagnostic code is active. Expected Result:The CID 0697 FMI 06 diagnostic code is NO longer active. Results:
OK - The CID 0697 FMI 06 diagnostic code is no longer active. The diagnostic code does not exist at this time. The initial diagnostic code may have been caused by a poor electrical connection that was corrected when a harness connector was disconnected and reconnected.Repair: Resume normal machine operation.STOP
NOT OK - The CID 0697 FMI 06 diagnostic code is active. The problem has not been corrected.Repair:
