transaxle output shaft. The frequency of the
square-wave signal increases with the speed of
the transmission output shaft.
The OSS sensor picks up the speed at the gear of
the parking lock.
The TCM uses the information from the OSS
sensor for the following parameters:
• Calculation of the degree of torque reductionthat needs to be requested by the PCM during
shifting.
• Calculation of the shift points.
• Calculation of the engaging and disengaging point for the TCC (lock-up function).
• Calculation of the current gear ratios by comparison of the TSS sensor signal.

2 • The torque converter lockup and adaptation
functions are deactivated.
• The wheel speed signal is transmitted by the ABS to the TCM via the HS-CAN data bus. This
signal serves as a substitute value.
• When the engine is restarted (ignition switched off for approx. 15 seconds), the transaxle is no
longer in limp home mode. There is no longer
a fault indication on the instrument cluster, and
the MIL is off. However, the fault remains stored
in the TCM. If the fault is still present, limp home
mode is reactivated.
The TFT sensor

The TFT sensor is located in the valve body and
is an integral component of the internal transaxle
wiring harness.

control saves the current speed as the target
speed.
Cruise control goes into STANDBY mode in the
following situations:
• Operation of the brake pedal
• Operation of the clutch pedal
• Operation of the parking brake
• If the driver operates the accelerator pedal andthe saved target speed is subsequently
exceeded for more than 5 minutes.
• Pressing any cruise control button for more than 2 minutes
• Intervention by the traction control or electronic stability program (for longer than 40 ms)
• Shifting of the gear selector lever to the "N" position (vehicles with automatic transmission
only)
• Minimum speed falls below 40 km/h.
• Occurrence of particular DTC (diagnostic trouble code)
• faulty signal from the backup lamp switch
Cruise control is switched off when the "OFF"
button is pressed.
If the accelerator pedal is pressed down, the
vehicle speed increases. As soon as the pedal is
released, the speed falls to the saved target value. The following components supply the signals
needed by the cruise control:
• The APP sensor.
– The APP sensor identifies the currentposition of the accelerator pedal and sends
a PWM (pulse width modulation) signal to
the PCM and an analog DC (direct current)
signal to the GEM.
– If one or both of the APP sensors fails, a fault is stored in the PCM fault memory and cruise
control cannot be activated.
• BPP switch – The BPP switch tells the PCM whether thevehicle is being braked. In its rest state the
switch is closed and sends an earth signal
to the GEM. This signal is sent via the CAN
to the PCM.
– The brake light switch is likewise connected to the GEM and is opened in the rest state.
When the vehicle is braked, the brake light
switch sends a signal to the GEM. This
compares the signals from the BPP switch
and the brake light switch. If a discrepancy
occurs, a fault is stored in the error memory
of the GEM. Cruise control cannot be
activated.
• CPP switch – The CPP switch sends a ground signal to theGEM as soon as the clutch is operated. This
signal is passed on by the GEM via the CAN
bus to the PCM. This then supplies the signal
to the cruise control.
– If the CPP switch is incorrectly installed or set, cruise control cannot be activated.
• Wheel speed sensors – The wheel speed sensors record the speedof all the wheels. The recorded speed values
are sent to the ABS module via a hard-wired
connection. The ABS module calculates a
vehicle speed signal (VS signal) from the
speed values and the wheel diameter. This
vehicle speed signal is transferred via the
CAN bus to the PCM and supplied to the
cruise control. If the vehicle speed signal is
faulty, cruise control cannot be activated.

• Parking brake switch.– The parking brake switch is hard-wired to theGEM. The parking brake switch sends a
signal to the GEM when the parking brake is
operated. The GEM activates the parking
brake indicator lamp in the instrument cluster.
If the parking brake indicator lamp is lit,
cruise control cannot be activated.
• Back-up light switch – The backup lamp switch is hard-wired to the GEM. The backup lamp switch sends a signal
to the GEM when reverse gear is engaged.
The GEM activates the reversing lamp.
Cruise control cannot be activated when
reverse gear is engaged.

The cruise control buttons are non-locking push
buttons. They are connected to the coil spring via
a hard-wired 9-pin plug connection.
The cruise control buttons operate according to
the resistance bridge circuit principle. The buttons
receive a 5 Volt reference voltage. When operated,
each button passes a particular voltage to the
GEM. The GEM measures this voltage and from
it determines which button has been pressed.
The operation of the cruise control buttons can be
checked by a simple measurement of the
resistance between pin 4 and pin 5 at the coil
spring 9-pin connector. A change of resistance
must occur when a button is pressed.
