Test 3: Individual Component Pressure Tests

Disconnect pneumatic line from malfunctioning actuator. See VACUUM DIAGRAMS . Connect Yellow connector on Vacuum/Pressure Tester (201 589 13 21 00) to malfunctioning actuator. Apply 8.7 psi (600 mbar) of pressure to actuator. If pressure loss is not substantial in one minute, check and repair pneumatic lines as necessary. See VACUUM DIAGRAMS . If pressure loss is substantial in one minute, replace actuator as necessary.
