Position Sensor (Left
This diagnostic code is recorded when the powertrain ECM reads the
Brake Pedal/Neutralizer)
signal voltage of the left brake pedal position sensor and the voltage is
Voltage Below Normal
too low. The operating range for the output voltage of the sensor is
or Shorted Low
approximately 0 DCV to 5.0 DCV. The output frequency of the position
sensor is approximately 500 hertz. The value of the sensor's duty cycle
is approximately 50% in the depressed position. The duty cycle of the
signal increases as the brake pedal is pressed. The value of the sensor's
duty cycle is approximately 85% in the pressed position. The duty cycle
of the signal decreases as the brake pedal is moved from the pressed
position to depressed. The value of the sensor's duty cycle is
approximately 15% in the pressed position. This code is generated when
the sensor has failed, the signal circuit in the harness is shorted to
ground, or the powertrain ECM has failed.
0793 03
Pressure Switch
The primary steering pressure switch is connected to two inputs of the
(Primary Steering)
powertrain ECM. One contact is open and the other contact is grounded
Voltage Above Normal
during correct operation. This FMI 03 means that the powertrain ECM
or Shorted High
has determined that both contacts are open.
0793 04
Pressure Switch
The primary steering pressure switch is connected to two inputs of the
(Primary Steering)
powertrain ECM. One contact is open and the other contact is grounded
Voltage Below Normal
during proper operation. This FMI 04 means that the powertrain ECM
or Shorted Low
has determined that both contacts are grounded.
0794 03
Secondary Steering
The primary steering pressure switch is connected to two inputs of the
Pressure Switch Voltage
powertrain ECM. One contact is open and the other contact is grounded
Above Normal or
during proper operation. This FMI 03 means that the powertrain ECM
Shorted High
has determined that both contacts are open.
0794 04
Secondary Steering
The secondary steering pressure switch is connected to two inputs of
Pressure Switch Voltage
the powertrain ECM. One contact is open and the other contact is
Below Normal or
grounded during proper operation. This FMI 04 means that the
Shorted Low
powertrain ECM has determined that both contacts are grounded.
0794 07
Secondary Steering
The CID 0794 FMI 07 diagnostic code is recorded if there is secondary
Pressure Switch
steering pressure when the relay is deactivated.
Mechanical System not
Responding
0795 07
Secondary Steering
This diagnostic code is generated when the powertrain ECM determines
Intermediate Relay
that the machine is moving via the transmission output speed sensor
Mechanical System not
and there is no secondary steering pressure when the relay is energized.
Responding
When the machine is at rest, this diagnostic code will always be
inactive.
