Schematic for the dual speed control |
This diagnostic code is associated with the dual speed control. The dual speed control is connected to two inputs of the Power Train/Chassis Electronic Control Module (ECM). One contact is open and the other contact is grounded during proper operation.
This FMI 03 means that the ECM has determined that the normally open contact and the normally closed contact are open.
Note: The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 1695 FMI 03 is active before performing this procedure.
System Response:
When this diagnostic code occurs, the ECM will limit the machine to reduced speed mode.
Test Step 1. CHECK THE DUAL SPEED CONTROL
- Turn the battery disconnect switch and the key start switch to the ON position.
- At the machine harness connector for the dual speed control place a jumper wire from contact 3 (wire R986-BU) to contact 4 (wire C209-BK).
- The status of the diagnostic code is active and the status of the diagnostic code is not active as the jumper wire is installed and the jumper wire is removed.
- Remove jumper wire that was installed in previous Test Step.
- At the machine harness connector for the dual speed control place a jumper wire from contact 2 (wire R985-WH) to contact 4 (wire C209-BK).
- The status of the diagnostic code is active and the status of the diagnostic code is not active as the jumper wire is installed and the jumper wire is removed.
Expected Result:
If the dual speed control is not the cause of the diagnostic code, the diagnostic code remains active. If the dual speed control has failed, the diagnostic remains not active.
Results:
- YES - The diagnostic code remains active the dual speed control has not failed. Proceed to Test Step 2
- NO - The diagnostic changes from an active state to a inactive state. The dual speed control has failed.
Repair: Repeat this test "CHECK THE DUAL SPEED CONTROL" in order to verify that the dual speed control has failed. Replace the dual speed control.
Stop.
Test Step 2. CHECK FOR AN OPEN CIRCUIT
- Turn the key start switch and the battery disconnect switch to the OFF position.
- Disconnect the J1 and J2 machine harness connectors from the ECM.
- At the machine harness connector for the dual speed control place a jumper wire from contact 3 (wire R986-BU) to contact 4 (wire C209-BK).
- At the J2 machine harness connector for the ECM, measure the resistance from the signal contact J2-62 (wire R986-BU) to frame ground.
- Remove jumper wire that was installed in previous Test Step.
- At the machine harness connector for the dual speed control place a jumper wire from contact 2 (wire R985-WH) to contact 4 (wire C209-BK).
- At the J2 machine harness connector for the ECM, measure the resistance from the signal contact J2-61 (wire R985-WH) to frame ground.
Expected Result:
The resistance that is measured is less than 5 ohms.
Results:
- YES - Each resistance measurement is less than 5 ohms. Proceed to Test Step 3.
- NO - The resistance measurements is greater than 5 ohms. There is an open in the machine harness.
Repair: Repair the machine harness or replace the machine harness. Verify that the diagnostic code is no longer active.
Stop.
Test Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS
- Inspect the contacts of the harness connectors and clean the harness connectors.
- Reconnect all the harness connectors.
- Turn the battery disconnect switch and the key start switch to the ON position.
- Operate the machine.
- Check the status of the CID 1695 FMI 03.
Expected Result:
The CID 1695 FMI 03 is active.
Results:
- YES - The CID 1695 FMI 03 is active. 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 this procedure again. If the cause of the diagnostic code is not found, replace the ECM. Refer to Systems operation, Troubleshooting, Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
Stop.
- NO - The CID 1695 FMI 03 is not active. 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.
