Diagnosis with GDS

The diagnostic system (GDS) provides the following information.
- Self diagnosis: Checking failure and code number (DTC).
- Current data: Checking the system input/output data state
- Actuation test: Checking the system operation condition.
- Additional function: Controlling other features including system option setting and zero point adjustment.
- Select the 'Car Model' and the 'Lane Keeping Assist System' to be checked in order to check the vehicle with the tester.
- Select the 'Current Data' menu to search the current state of the input/output data.
