Automated Manual Transmission 22 Clutch Bleeding: Clutch bleeding procedure: The guidelines of the procedure are illustrat- ed below: When? For filling after draining for KIT repairs. After KIT repairs following replacement of hydraulic parts (valves, pump, pressure sensor, delivery pipe) General KIT operation Why? The routine is designed to eliminate the possible presence of air in the hydraulic circuit following the replacement of one of the above mentioned components carrying out 15 clutch opening/closing cycles with the oil pump activated. What tools are needed? Diagnosis equipment NOTES: The procedure takes approximately 1 minute. Power latch takes approximately 15 seconds. To verify the implementation of the proce- dure it is possible to hear the operating of the clutch solenoid valve and the activation of the power unit pump. The procedure is performed under the fol- lowing conditions: Engine off Brake pressed Ignition ON Clutch position sensor ok Clutch actuator ok The procedure will end without indicating an error code if any one of the conditions listed above does not occur. Hydraulic circuit depressurization: The guidelines of the procedure are illustrat- ed below: When? Before the hydraulic components replace- ment KIT repair (valves, pressure sensor, supply pipe, etc.). Why? The routine is designed to drain the hy- draulic circuit sending it to the kit fluid reservoir to allow the replacement of the above components, carrying out 26 clutch opening/closing cycles with the oil pump deactivated. Oil level check. What tools are needed? Diagnosis equipment. NOTES: The procedure takes approximately 1 minute. Power latch takes approximately 15 seconds. To verify the implementation of the proce- dure it is possible to hear the operating the clutch solenoid valve. Check (read RDI 1C06) that the pressure in the hydraulic circuit is under the accumulator pre- charge threshold (approx. 2-3 bar). The procedure must be carried out in the fol- lowing conditions: Engine off Brake pressed Ignition ON Clutch position sensor ok Clutch actuator ok The procedure will end with self-calibration KO if any one of the conditions listed above does not occur.
