Trouble Diagnostics When Using GDS
1.
The BCM can be diagnosed by using the GDS. The BCM communicates with the GDS which then displays inputs and outputs along with codes.
2.
To diagnose the BCM function, select the vehicle model and BCM.

3.
To consult the present input/out value of BCM, "Current DATA". 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 functional test on BCM outputs, select "Actuation Test"
