Diagnosis Using GDS

  1. The heating, ventilation, and air conditioning system faults can be quickly diagnosed using the Global Diagnostic System (GDS). ※ The GDS provides the following information: (1) Self-diagnosis: Check and display of diagnostic trouble codes (DTC). (2) Current data: Check the input/output status of system data. (3) Active test: Check the operating status of the system. (4) Additional functions: Other controls such as system option and zero point adjustment.
  2. Select "Vehicle Model" and the system to be checked to inspect the vehicle with the tester.
  3. Select the "Current Data" menu to check the current input/output data status. The input/output data for the sensors related to the in-car temperature sensor can be checked.
