Diagnosis With GDS

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (GDS).

(1)	Self diagnosis : Checking failure and code number (DCT)

(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

The BCM communicates with the GDS and then reads the input/output value and drives the actuator.

2.	Select the 'Steering wheel remote control' and the system to be checked in order to check the vehicle with the tester.

Select the 'Steering wheel remote control (SWRC)' to check the Steering wheel remote control (SWRC)

Select 'Sensor Data' and 'Steering wheel remote control (SWRC)' to check the Instrument Panel Module (Sensor Data).

4.	Select the "Current date" menu to search the current state of the input/output data. The input/output data for the sensors corresponding to the 'Premium AVN' can be checked.

Removal

1.	Disconnect the negative (-) battery terminal.

2.	Remove the driver airbag module. (Refer to Restraint - "Driver Airbag (DAB) Module and Clock Spring")
