D6.08 MEASURING SENSORS AND SIGNAL SWITCHES The TCU detects the measures needed for transmission control by means of a series of sensors fitted in the car and through a CAN line communicating with the engine ECU or the ASR/MSR drive control ECU and the instrument panel. The TCU interfaces with all the sensors and all the actuators by means of a specific harness (see Table P - ELECTRICAL SYSTEM). NOTES After replacing a sensor, you must execute a self-learning cycle ( D 6.12). Gear Selection Position (B) and Gear Engagement (A) Sensors These sensors are installed on the gear engagement and selection actuator and they detect the position of the piston actuating the selection and engagement of gears. IThese sensors are "contact-less" and they work similarly to the clutch position sensor. Inside the sensor there is an electronic unit that converts electric signals in
0÷5 V. NOTES We suggest you replace the sensors (especially the gear selection sensor) after having removed the actuator form the gearbox housing, in order to avoid extracting the sensor's control shaft too. • Remove the actuator from the gearbox housing ( D 6.07). Place the actuator so that the sensor is vertical to the assembly axis. The sensors (A) and (B) are fixed to the actuator by means of screws (1) that fasten also the holding clamp (2) belonging to the cable bundle for connection to the F1 harness. For connection to the system, see Table P - ELECTRICAL SYSTEM. Clutch Position Sensor (C) In order to detect the thrust bearing clutch position, the system is fitted with an LVDT sensor (Linear Variation Differential Transformer).
