Diagnosis With GDS
1.
The body electrical system can be quickly diagnosed for faulty parts using vehicle diagnostic system (GDS).
The diagnostic system (GDS) provides the following information:

Self diagnosis : Checking the failure code (DTC) and display
(2)
Current data : Checking the system input/output data state
(3)
Actuation test : Checking the system operation condition

Additional function : Other controlling such as he system option and zero point adjustment
The BCM communicates with the GDS and then reads the input/output value and drives the actuator.
