Schematic of the "Priority Solenoid" valve
This diagnostic code is recorded when the current of the solenoid is below normal. 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 0697 FMI 05 is active before performing this procedure.Note: The following procedures should be performed while the engine is OFF. This will ensure that the machine will not move when the parking brake switch is in the OFF position. Test Step 1. CHECK THE SOLENOID.
Turn the key start switch to the ON position. Ensure that the CID 0697 FMI 05 diagnostic code is on hold.
Disconnect the machine harness from the priority valve solenoid.
At the machine harness connector for the solenoid, place a jumper from contact 1 to contact 2.
Observe the status of the fault present indicator. Expected Result:The CID 0697 FMI 05 diagnostic code remains active. Results:
YES - The circuit is correct. The solenoid has failed. repeat this test step in order to verify that the solenoid has failed.Repair: Replace the solenoid.STOP
NO - The diagnostic code remains. Proceed to test step 2.Test Step 2. CHECK THE HARNESS FOR AN OPEN.
Turn the key start switch to the OFF position.
Disconnect the J1 and J2 machine harness connectors from the ECM.
The jumper wire remains installed.
At the machine harness connector J1 and J2, measure the resistance from J1-12 (solenoid signal) to J2-4. Expected Result:There should be less than 5.0 ohms resistance.Results:
OK - The machine harness is correct. Proceed to test step 3.
NOT OK - There is an open circuit in the machine harness. The harness has failed.Repair: The open is in wire K978-BU(Blue) or in wire F761-BR(Brown) of the machine harness. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn 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 OFF position.
Determine if the diagnostic code is present. Expected Result:The CID 0697 FMI 05 diagnostic code is active. Results:
YES - The problem has not been corrected. The ECM has failed.Repair: Exit this procedure and perform the diagnostic code procedure again. If the problem persists, the ECM may have failed. Prior to replacing an ECM, always contact your dealership's "Technical Communicator" for possible consultation with Caterpillar. This consultation may greatly reduce repair time. See the Troubleshooting, "Electronic Control Module (ECM) - Replace".STOP
NO - The diagnostic code is NOT present.Repair: The problem does not exist at this time. The initial problem was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.STOP
