Hyundai Santa Fe: Coupling Assembly / Direct Electro Hydraulic Actuator Coupling. Repair procedures
| •
|
All units are filled up with coupling fluid (ultra-low viscosity
ATF) prior to shipping. Inspection, fill-up, and replacement
of coupling fluid is therefore not necessary (zero maintenance,
lifetime fluid).
|
|
|
Coupling Maintenance Precautions
Maintain the coupling at a horizontal level.
| •
|
Refer to the handling caution level (A) when servicing the coupling
(removal, installation, replacement, etc.).
|
| •
|
Always maintain a horizontal posture.
|
|
| •
|
Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|

|
1. |
To install, reverse the removal procedures.
|
• |

|
|
2. |
After replacing the coupling, reset the 4WD ECU's clutch learing using
the diagnostic tool.
(Refer to 4WD Control System - "Repair procedures")

Description
4WD ECU processes signals from various sensors and determines the current road
and driving conditions. The ECU then utilizes this information to implement
precision control over the 4WD coupling's multi-plate clutch and variably adjust
the amount of torque delivered tothe rear wheels...
Description
The 4WD ECM controls the Pump Motor Pump (Actuator) to generating an oil pressure.
The pressure engages a multiple disk clutch to transfer torque to the rear wheels...
