  3. In the electrical system, malfunctions can be quickly diagnosed using the Global Diagnostic System (GDS).
    1. Self-Diagnosis: Malfunction and Code Number Check (DCT)
    2. Current Data: Check the system input/output status.
    3. Actuation Test: Check the system operating status
    4. Additional Functions: Controls other functions, including system parameter setting and zero point adjustment.
    The BCM communicates with GDS, reads the input/output value, and operates the actuator.
  4. Select "Steering Wheel Remote Control" and the system to be checked to inspect the vehicle with the tester.
  5. Select "Steering Wheel Remote Control (SWRC)" to inspect the steering wheel remote control (SWRC).
    Select "Sensor Data" and "Steering Wheel Remote Control (SWRC)" to inspect the instrument panel module (sensor data).
  6. Select the "Current Data" menu to check the current input/output status. Input/output data for sensors applicable to "Premium AVN" can be checked.
Diagnosis Using GDS
