Location of the ripper raise solenoid

This solenoid is connected to the Implement ECM 2. The Implement ECM 2 sends the diagnostic information to the Machine ECM via the CAN data link. This diagnostic code is associated with the return circuit for the Ripper Raise Solenoid. The FMI 03 means that the Implement ECM 2 has determined that the voltage of the solenoid circuit is above normal.

The possible causes of the diagnostic code are listed:

• The solenoid has failed.

• The energize circuit of the solenoid is shorted to the +battery circuit.

• The Implement ECM 2 has failed. This is unlikely.

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 3188 FMI 03 is active before performing this procedure.

Note: Use a digital multimeter for the measurements in this procedure.

Test Step 1. CHECK THE SOLENOID CIRCUIT FOR A SHORT TO THE +BATTERY CIRCUIT.

1. Turn the key start switch and the disconnect switch to the OFF position.

2. Disconnect the machine harness from the solenoid and the Implement ECM 2.

3. At the machine harness connector for the Implement ECM 2, measure the resistance from contact 50 (wire J921-PK) to all contacts that are used in the machine harness connectors for the Implement ECM 2.

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 - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between contact 50 (wire J921-PK) and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness.STOP

Test Step 2. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.

1. Inspect the harness connectors. Clean the contacts of the harness connectors and check the wires for damage to the insulation that is caused by excessive heat, corrosion, or chafing.

2. Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit.

3. Reconnect all harness connectors in order to make sure that the connectors are fully seated. Also, make sure that the clips for each connector are completely fastened.

4. Turn the disconnect switch and the key start switch to the ON position.

5. Operate the machine.

6. Determine if the diagnostic code is active.

Expected Result:

The diagnostic code is active.

Results:

• YES - The diagnostic code is active. The problem has not been corrected.

  Repair: Check the circuit again. It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. Prior to replacing an ECM, always contact your dealership for possible consultation with AVSpare. This consultation may greatly reduce repair time. If the ECM requires replacement, refer to Troubleshooting, "Electronic Control Module (ECM) - Replace".

  STOP

• NO - The diagnostic code is not active. 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. The problem does not exist at this time. Resume normal machine operation.STOP
