Trouble Diagnostics When Using Diagnosis Tool

1. 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.
2. To diagnose the BCM function, select the menu of model and body control module.




3. To consult the present input/out value of BCM, "02. INPUT/OUTPUT MONITORING". It provides information of BCM input/output conditions of power supply, turn signal/brake lamp, headlamp, door, locks, outside mirror, wiper, auto-light and transmitters etc.








4. To perform compulsory operation on BCM input factors, select "04. ACTUATION TEST".
