Schematic of the Solenoid for the Left Steering BrakeThis diagnostic code is for the solenoid for the left steering brake.This diagnostic code is recorded when current of the solenoid is below normal. Test Step 1. CHECK THE SOLENOID.
Turn the key start switch to the ON position. Do not start the engine. Ensure that the Active Events screen shows a problem.
Place the parking brake switch in the OFF position.
Disconnect the machine harness from the solenoid.
At the machine harness connector for the solenoid, place a jumper from contact 1 to contact 2.
Observe the status of the Active Events screen. Expected Result:The Active Events screen changes as the jumper is installed and the jumper is removed.Results:
YES - The Active Events screen changes.Repair: The circuit is correct. The solenoid has failed. Repeat this step in order to verify the solenoid failure. Replace the solenoid. Stop.
NO - The Active Events screen does not change. Proceed to Test Step 2.Test Step 2. CHECK THE SOLENOID CIRCUIT FOR AN OPEN.
Turn the key start switch to the OFF position.
Disconnect the machine harness connectors J1 and J2 from the ECM.
At the machine harness connector for the solenoid, place a jumper from contact 1 to contact 2.
At machine harness connector J2, measure the resistance from the solenoid signal contact to J2-3.Expected Result:There should be less than 5.0 ohms resistance. Results:
OK - There is less than 5.0 ohms resistance. The machine harness is correct. Proceed to Test Step 3.
NOT OK - There is not less than 5.0 ohms resistance. Repair: There is an open circuit in the machine harness. The open is in the wire for the solenoid signal 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.
Enter the Caterpillar VIDS and clear all inactive diagnostic codes.
Operate the machine.
Stop the machine and place the parking brake switch in the ON position.
Determine if the CID 0689 FMI 05 for the solenoid is present.Expected Result:The Active Events Screen shows a problem. Press the "MORE" button in order to display the Diagnostic Code.Results:
YES - The Active Events screen shows a problem.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 Active Events screen does not show a problem.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.
