Trouble Diagnostics When Using Diagnosis Tool: Notes

The body control module can diagnose by using the diagnosis tool more quickly.
The BCM communicates with the diagnosis tool and then reads the input/output value and drives the actuator.
To diagnose the BCM function, select the menu of model and body control module.
