Schematic of the Right Brake SolenoidThis diagnostic code is for the Right Brake Solenoid.This diagnostic code is recorded when current of the solenoid is below normal. Note: Ensure that the diagnostic code is active.Test Step 1. CHECK THE SOLENOID.
Turn the key start switch to the ON position. Do not start the engine.
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 diagnostic code. Expected Result:The diagnostic code changes as the jumper is installed and the jumper is removed. Results:
YES - The diagnostic code changes as the jumper is installed and the jumper is removed.Repair: The circuit is correct. The solenoid has failed. Repeat this step in order to verify the solenoid failure. Replace the solenoidSTOP
NO - The diagnostic code does NOT change as the jumper is installed and the jumper is removed. 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 J1, measure the resistance from the solenoid signal contact to J1-59.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 contact 1of the machine harness. Repair the machine harness or replace the machine harnessSTOPTest 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.
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 0690 FMI 05 for the solenoid is present.Expected Result:CID 0690 FMI 05 for the solenoid is present. The diagnostic code is active.Results:
YES - CID 0690 FMI 05 for the solenoid is present. The diagnostic code is present.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 Troubleshooting, "Electronic Control Module (ECM) - Replace".STOP
NO - CID 0690 FMI 05 for the solenoid is not present. 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 operationSTOP
