Illustration 1 g01271022
Schematic of the Right Drive (Forward) Pump Solenoid CircuitThis diagnostic code is recorded when the ECM reads the voltage of the solenoid circuit as being above normal or shorted to +battery.The possible causes of this diagnostic code are listed:
The energize circuit of the solenoid is shorted to the +battery circuit.
The ECM has failed. This is unlikely. Note: The following test procedure may create other diagnostic codes. Clear the diagnostic codes when the problem has been corrected. Verify that cid 1705 fmi 05 is active before performing this procedure.System Response:The diagnostic will generate a cid 1705 fmi 03 level 2 warning. If the machine is traveling, the machine will be brought to a stop. The parking brake will engage. The park brake will not release until the diagnostic has been corrected and the hystat lever has been brought back to neutral.Test Step 1. CHECK THE SOLENOID CIRCUIT FOR A SHORT TO THE +BATTERY CIRCUIT.
Turn the key start switch to the OFF position.
Disconnect the machine harness from the solenoid.
Disconnect J1 and J2 machine harness connectors from the ECM.
At the machine harness connector, measure the resistance from signal contact J1-51 (wire K947-YL) to all contacts that are used in the machine harness connectors for the ECM.Expected Result:Each resistance measurement should be greater than 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to test step 2.
NOT OK - One or more resistance measurements is not correct. There is a short in the machine harness. The short is between signal contact J1-51 (wire K947-YL) and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts of the harness connectors and clean the contacts.
Reconnect all harness connectors.
Turn the key start switch to the ON position.
Clear all of the logged diagnostic codes.
Operate the machine.
Check if the CID 1705 FMI 03 is present. Expected Result:The diagnostic code for the solenoid is NOT present. Results:
YES - The diagnostic code is NOT present. The diagnostic code does not exist at this time. Repair: The initial diagnostic code 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
NO - The diagnostic code has not been corrected. The ECM may have failed. Repair: It is unlikely that the ECM has failed. Exit this procedure and perform the procedure again. Prior to replacing an ECM, always contact your dealership's Technical Communicator for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the cause of the diagnostic code is not found, replace the ECM. SeeTroubleshooting, "Electronic Control Module (ECM) - Replace".STOP
