Hyundai Genesis: Premium AVN System / Steering Wheel Remote Controller (SWRC) Repair procedures

Inspection

Steering Wheel Remote Control system (SWRC) can be diagnosed by GDS because it receives and sends signals through CAN communication.

1.	Check for resistance between terminals in each switch position(LH). [Audio] Switch Connector terminal Resistance (±5%) Speech Recognition 6~8 18.81k? SEEK UP 6~8 4.51k? SEEK DN 6~8 2.11k? Mode 6~8 6.71k? SEND 6~8 430? END 6~8 1.11k? MUTE 1~8 0 VOL UP 2~3 - VOL DN 2~3 -

2.	Check for resistance between terminals in each switch position(RH). [Cruise] Switch Connector terminal Resistance (±5%) CANCEL 2~3 180? RES+ 2~3 550? SET- 2~3 330? Cruise ON/OFF 2~3 880? Space betweencars 2~3 2.54k?

1.

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (GDS). The diagnostic system(GDS) provides the following information. (1) Self diagnosis : Checking failure and code number (DTC) (2) Current data : Checking the system input/output data state (3) Actuation test : Checking the system operation condition (4) Additional function : Controlling other features including system option setting and zero point adjustment

2.	Select the 'Car model' and the steering wheel remote control system (SWRC) to be checked in order to check the vehicle with the tester.
