Conditions Which Generate This Code:
This diagnostic code is recorded when the system voltage is below 9 VDC. When this diagnostic code is recorded the transmission will shift into neutral.
The possible causes of this diagnostic code are listed below:
- The wiring in the machine harness has failed.
- A charging system component has failed.
- The system has a low voltage.
- The ECM has failed. This is unlikely.
Test Step 1. CHECK THE BATTERY VOLTAGE.
- Start the engine and run at high idle for several minutes.
- Measure the battery voltage at the battery posts.
Battery voltage should be greater than 9 VDC.
- OK - Battery voltage is greater than 9 VDC. Battery voltage is correct. Proceed to Test Step 2.
- NOT OK - Battery voltage is not greater than 9 VDC.
Repair: The charging system is not correct. Check the charging system. See Troubleshooting, "Charging System".
Test Step 2. CHECK THE SYSTEM VOLTAGE AT THE ECM.
- The engine must still be running at high idle.
- DO NOT DISCONNECT the machine harness from the ECM. At connector "J1" of the ECM, prepare to make a voltage measurement by using the 7X-1710 Multimeter Probe.
- At the machine harness for the ECM, insert the probe into the back of connector "J1". Measure the voltage (VDC) between J1-39 (wire 126-RD) and J1-23 (wire 202-BK).
Voltage should be greater than 9 VDC.
- OK - Voltage is greater than 9 VDC. Battery voltage is correct. Proceed to Test Step 3.
- NOT OK - Voltage is not greater than 9 VDC.
Repair: The machine harness is not correct. Repair the machine harness or replace the machine harness.
Test Step 3. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.
- Remove connectors "J1" and "J2" from the ECM. Inspect the contacts and clean the contacts of the harness connectors.
- Reconnect all harness connectors.
- Turn the key start switch to the ON position.
- Operate the machine.
- Determine if CID 0168 FMI 04 is present.
CID 0168 FMI 04 is present.
- YES - CID 0168 FMI 04 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 the ECM, always contact your dealership for possible consultation with AVSpare. This consultation may greatly reduce repair time. If the cause of the diagnostic code is not found, replace the power train ECM. See the Troubleshooting, "Electronic Control Module (ECM) - Replace".
- NO - CID 0168 FMI 04 is not present.
Repair: The diagnostic code is NOT present. 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.
