Engine Clutch Actuator Repair procedures
Removal
Warning
Initialization and air bleeding procedure by using KDS can not be performed if the high voltage battery SOC is charged lower than 35%.
- Additional function which related to engine clutch can not be
operated if high voltage battery SOC is charged too low(lower
than 10%) or too high(higher than 90%), because of system limitation.
(Additional function which related to engine clutch : learning engine clutch/motor resolver, removing air in engine clutch oil pressure line, stabilizing engine clutch oil pressure line, stabilizing engine clutch hardware delivery torque, lerning engine clutch inspection of a vehicle and initialization of inspection information)
- Turn the ignition switch OFF and disconnect the battery (-) terminal.
- Remove the under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover")
- Disconnect the engine clutch actuator connector (A) and hose (B).
- Loosen the engine clutch actuator bolts (A) and then remove the engine clutch actuator.
Tightening torque : 21.6 - 26.5 N.m (2.2 - 2.7 kgf.m, 15.9 - 19.5 lb-ft)
Warning
Make sure that the hydraulic fluid or foreign substance does not enter the connector assembly of the actuator.
Installation
- Install in the reverse order of removal.
Warning
Before installing the engine clutch actuator, check the assembled state of the O-rings (A).
- After replacing the engine clutch actuator, operate the followings in order using KDS.
(1) Perform initialization of the engine clutch inspection line learning and diagnostic information.
(2) Bleed the air from engine clutch hydraulic pressure line
Warning
Be sure to bleed air from the engine clutch hydraulic pressure line at outside temperature between 0 - 40ºC (32 - 104ºF). If not, the air bleeding would be not done well.
Warning
Refil the hydraulic fluid to MAX-MIN level, if the fluid is lower than MIN level while performing the air bleeding.
(3) Perform engine clutch/motor resolver adaptation.
(4) Perform stabilization of the engine clutch hardware transfer torque.
