With the engine switched off, connect connector EX09 (1) from case N° 1806338000 of the diagnostic equipment and the 5 bar pressure transducer EX06 in the section of pipe between the actuator and the solenoid valve.Select intake pressure measuring gauge in instrument mode.Start up the engine and let it idle, then wait until pressure pressure stabilizes.The reading should not exceed 590 and 720 mbar (450-550 mmHg).Select "pressure gauge" on the Examiner and prepare for the acquisition of data in "intake pressure" mode with a 2000 mmHg end of scale and selection time of 10 seconds.Go out on the road (keeping to the speed limits in force) and carry out the following test. On a stretch of road out of town, initiate the graph acquisition by pressing start on the diagnostic equipment and after about 5 with 2nd gear engaged let the engine speed reach 4000 rpm and engage 3rd gear.Display the resulting graph and read a value of about 980 mbar (745 mmHg) for the maximum peak corresponding to a pressure reading of 20 mbar.
