Speed Sensor
This code is recorded when the powertrain ECM reads the speed sensor
(Transmission Output
signal as being erratic, intermittent, or incorrect. There are two speed
Speed 2) Data Erratic,
sensors for transmission output speed, the transmission output speed
Intermittent, or Incorrect
(TOS) sensor 1 (leading) and the transmission output speed (TOS)
sensor 2 (trailing). The powertrain ECM determines the existence of
this diagnostic code by comparing the signals from sensor 1 and the
signals from sensor 2. This diagnostic code is recorded when one of the
sensors shows a valid speed signal above the minimum and the other
sensor signal is below the dropout signal level. Failures of the
transmission output speed sensor will be shown only while the machine
is moving. This code is generated when the signal from TOS Sensor 2
(trailing) to the powertrain ECM is incorrect. When this code is
generated, transmission shifting may be harsh, transmission control
may be unable to determine the direction of travel and/or transmission
control will be unable to determine the ground speed of the machine.
0702 02
Lever Switch
The transmission gear selector switch has seven inputs to the powertrain
(Transmission Shifting/
ECM. During normal operation, one input is grounded and the other
Direction) Data Erratic,
inputs are open. If the powertrain ECM detects more than one input is
Intermittent, or Incorrect
grounded, a circuit failure is present. This code is generated when there
is a harness fault or a failed switch.
0702 03
Lever Switch
The transmission gear selector switch has seven inputs to the powertrain
(Transmission Shifting/
ECM. During normal operation, one input is grounded and the other
Direction) Voltage
inputs are open. This diagnostic code of FMI 03 means that the
Above Normal or
powertrain ECM has determined that all contacts are open.
Shorted High
0737 03
Position Sensor (Left
This diagnostic code is associated with the Left Brake Pedal Position
Brake Pedal/Neutralizer)
Sensor. The FMI 03 means that the powertrain ECM has determined
Voltage Above Normal
that the voltage of the circuit for the sensor is above normal. This code
or Shorted High
is generated when the signal circuit for the sensor is open, the signal
circuit for the sensor is shorted to the +battery circuit, the sensor has
failed, the power circuit or the ground circuit has failed, or the
powertrain ECM has failed.
