Conditions Which Generate This Code:
Illustration 1 g01362188
Connection of the parking brake switchThis diagnostic code is associated with the parking brake switch. The switch is connected to two inputs of the ECM. The inputs are "Normally Open" and "Normally Closed". One of the inputs is open and the other input is grounded during proper operation.The FMI 2 means that the ECM has determined that the "Normally Open" and "Normally Closed" circuits are in the same state.Note: The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of SPN 117 FMI 2 is active before performing this procedure.Test Step 1. CHECK THE OPERATION OF THE SWITCH
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector or the wires from the switch.
Connect one lead from the multimeter to the common contact (A) for the switch.
Connect the other lead from the multimeter to the normally open contact (B) for the switch.
Measure the resistance between contact A and contact B. Note the resistance.
Disconnect the lead from contact B and connect the lead to the normally closed contact (C).
Measure the resistance between contact A and contact C. Note the resistance.Expected Result:The resistance from contact A to contact B is greater than 5000 ohms, and the resistance from contact A to contact C is less
