1. AWD ECU

Description and operation

Description

The AWD ECU distributes the driving force to the front/rear wheel through controlling the multi plate clutch on the AWD transfer case by analyzing the input information, i.e. the wheel speed, accelerator and steering angle depending on the road condition and driving state. The AWD vehicle has different power transmitting conditions depending on the driving/road conditions. The vehicle speed is transmitted through CAN communication from ABS/ESP ECU. The information from the CAN communication includes the APS which indicates the driver’s intention of acceleration, engine torque, ABS/ESP operation signal and gear position. The AWD ECU controls the DC motor, warning lamp and indicating lamp and communicates with the tester equipment. When a vehicle runs at normal speed higher than 60KPH on regular roads, it is controlled under the 2WD conditions. The ECU decides the driving force on the front and rear wheel by receiving the signals from all sensors depending on the driving conditions, i.e. abrupt starting, turning and driving on the low friction road, and the optimized torque which is proper to the driving condition is transmitted to the front wheel through calculating and controlling the transmitted torque data.

Repair procedures

Removal

1.	Turn ignition switch OFF and disconnect the negative (-) battery cable.

2.	Remove the crash pad lower panel. (Refer to Body - "Crash Pad Lower Panel")

3.	Remove the knee airbag. (Refer to Restraint - "Knee Airbag (KAB) Module")

4.	Disconnect the AWD ECU connector (A).

5.	Loosen the AWD ECU bracket nuts and then remove the AWD ECU (A).

Installation

Checking the engine oil level ■ THETA II 2.0L T-GDI Engine (Gasoline) ■ Lambda II PE 3.3L T-GDI Engine (Gasoline) 1. Be sure the vehicle is on level ground. 2. Start the engine and allow it to reach normal operating temperature. 3. Turn the engine off and wait for a few minutes (about 5 minutes) for the oil to return to the oil pan.

Kia Stinger (CK) 2018-2023 Service Manual: Lane Keeping Assist (LKA) system

The Lane Keeping Assist (LKA) system is designed to detect the lane markers on the road with a front view camera at the front windshield, and assists the driver's steering to help keep the vehicle in the lanes. When the system detects the vehicle straying from its lane, it alerts the driver with a visual and audible warning, while applying a slight countersteering torque, trying to prevent the vehicle from moving out of its lane.
