  2. In the body electrical system, a fault can be quickly diagnosed using the Global Diagnostic System (GDS). The GDS provides the following information.
    1. Self-diagnosis: checks for malfunctions and the number of codes (DTC)
    2. Current data: checking the input/output status of the system
    3. Operation check: checks the operating conditions of the system
    4. Additional function: controls other functions, including additional system setup and zero point adjustment
  3. Select "Vehicle Model" and "Body Control Module (BCM)" to check the vehicle with the tester.
  4. Select the "Current Data" menu to check the current status of inputs and outputs.
Verification (with GDS)
