Schematic for the LSI Hydraulic Lockout Override SwitchThis diagnostic code is associated with the Longitudinal Stability Indicator (LSI) Hydraulic Lockout Override Switch. The FMI 02 means that the ECM has determined that the signal is erratic, intermittent, or incorrect. The ECM could be receiving invalid combinations from the circuit.System Response:The system will default to no active LSI override.Test Step 1. CHECK THE CONTINUITY OF THE SWITCH IN THE NORMAL POSITION
Turn the key start switch and the disconnect switch to the "OFF" position.
Remove the switch from the dash.
Unplug the switch from the wire harness.
With the switch in the Normal position, check resistances from terminal "2" to each of the following: terminals 1, 3, 4 and 6. Next check resistances from terminal "5" to each of the following: terminals 1, 3, 4 and 6.Expected Result:All of the resistance measurements are greater than 5000 Ohms.Results:
OK - All measured resistances are greater than 5000 Ohms. Proceed to Test Step 2.
NOT OK - One or more resistance is less than 5000 Ohms.Repair: The switch has failed. Replace the switch.STOPTest Step 2. CHECK THE CONTINUITY OF THE SWITCH IN THE OVERRIDE ON POSITION
Press and hold the switch in the Override ON position.
With the switch held in the "ON" position, check resistances from terminal "2" to each of the following: terminals 1, 3, 4 and 6. Next check resistances from terminal "5" to each of the following: terminals 1, 3, 4 and 6.Expected Result:The resistance from terminal 2 to terminal 3 should be less than 5 Ohms. The resistances from terminal 2 to terminals 1, 4, and 6 is greater than 5000 Ohms.The resistance from terminal 5 to terminal 6 should be less than 5 Ohms. The resistances from terminal 5 to terminals 1, 3, and 4 is greater than 5000 Ohms.Results:
OK - All measured resistances are correct. Proceed to Test Step 3.
NOT OK - One or more resistances are NOT correct.Repair: The switch has failed. Replace the switch.STOPTest Step 3. CHECK THE CONTINUITY OF THE SWITCH IN THE OVERRIDE OFF POSITION
Press and hold the switch in the Override OFF position.
With the switch held in the "OFF" position, check resistances from terminal "2" to each of the following: terminals 1, 3, 4 and 6. Next check resistances from terminal "5" to each of the following: terminals 1, 3, 4 and 6.Expected Result:The resistance from terminal 2 to terminal 1 should be less than 5 Ohms. The resistances from terminal 2 to terminals 3, 4, and 6 is greater than 5000 Ohms.The resistance from terminal 5 to terminal 4 should be less than 5 Ohms. The resistances from terminal 5 to terminals 1, 3, and 6 is greater than 5000 Ohms.Results:
OK - All measured resistances are correct. Proceed to Test Step 4.
NOT OK - One or more resistances are NOT correct.Repair: The switch has failed. Replace the switch.STOPTest Step 4. CHECK THE HARNESS
The key start switch and the disconnect switch remain in the "OFF" position.
The switch remains disconnected from the harness.
Disconnect the "J1" and "J2"
