Clutch wear
The reading of the clutch position sensor also determines the state of wear of the clutch.
The values that determine deterioration are read with the LaRa-AS (109000)in the 0 H D V X U H P H Q W Y D O X H V for the
E-GEAR system, channel 10 ( ) L J ):
• Line 3 indicates the real clutch position
• Line 4 indicates the initial clutch position
The difference between the 2 values determines the thickness of the clutch, which is deteriorated when less than
5.6 mm.

In addition to the value calculated by the difference of lines 3 and 4, also the other data establish the state of clutch
wear: • Line 1 indicates the degree of deterioration of the clutch (the clutch is deteriorated when the value is higher
than 15000)
• Line 2 indicates the Kiss Point of the clutch (the clutch is deteriorated when the value is higher than 800)

The kiss point is self tuned at each cranking when the gearbox is in neutral. The engine is colder than 70C and the
clutch estimated temperature is colder than 70C.

For a fast adaptation of kiss point an LaRa-AS (109000)service is implemented.
The range is 300bit < Kisspoint < 800bit (the frequent value is between 350 and 550 bit).
The routine is activated if the following condition are true: • The engine is ON
• No gear is engaged
• The clutch kiss point self tuning has never been performed or a special service is asked by the tested
and it is suspended if one of the following condition is true:
• a new cranking is requested during the self tuning
• the clutch is not able to open
• the clutch closure phase is completed and no clutch rotation is detected
• a gear is requested
• a failure is detected on the clutch position sensor or on the gear valves

switched on, and if the hydraulic pressure is lower than a limit the pump is activated for maximum 4 seconds.

In the car there’s a relay that releases the cranking. This relay is controlled by E-Gear TCU.
The cranking is only released if the brake is pushed and not paddles an R switch pushed.
The cranking can be done also with a gear engaged. The system will engage the neutral before release the cranking. 3 L F N X S
The pick up is related to the gas pedal position and how it’s pushed.
To perform good pick up is important to keep constant the gas pedal.
During pick up is calculated the clutch wear index, if the engine and clutch temperatures are in a range.

better keeping constant the gas pedal. The gearshift speed and comfort quality depend on the gas pedal posi-
tion and engine speed.
• Automatic Mode and Automatic Sport Mode: the gearshift are performed directly from the E-Gear TCU, that
decides when to perform them according to the gas pedal position and vehicle speed.
• Underspeed: in order to avoid engine stalling if the driver doesn’t require any DW, E-Gear TCU perform itself
them when the engine speed becomes too low.
• Overspeed: in order to avoid engine limiter intervention the automatic gearshift is done when the maximum
engine speed is reached. This Function is not available in CORSA Mode.
