Schematic of the Solenoid for the Right Steering ClutchThis diagnostic code is recorded when the current of the solenoid is below normal. Note: Ensure that the diagnostic code for the solenoid is showing on the Active Events screen. This procedure can cause new diagnostic codes to be recorded. Ignore these created problems. When the procedure is completed, clear the created problems. Test Step 1. CHECK THE SOLENOID.
Turn the key start switch to the ON position. Ensure that the 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 diagnostic code is displayed and the diagnostic code is not displayed as the jumper is installed and the jumper is removed.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 SIGNAL CIRCUIT FOR THE SOLENOID 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 machine harness connector J1 and J2, measure the resistance from J1-18 (solenoid signal) to J2-3 or to J1-7.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 F789-YL or in wire 975-WH of the machine harness. Repair the machine harness or replace the machine harness. Stop.Test Step 3. DETERMINE 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.
Access the VIDS and 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 diagnostic code is present. The Active Events screen shows a problem.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 for possible consultation with Caterpillar. This consultation may greatly reduce repair time. See the Testing and Adjusting, "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.
