Relay Box: Testing and Inspection

Inspection

1. The ICM (Integrated Circuit Module) can be diagnosed by using the GDS more quickly.
The BCM communicates with the GDS and then reads the relay value and drives the actuator.
2. To diagnose the ICM relay function, select the menu of vehicle model and body control module.
3. Select "Input/output monitoring", if you want to check current data of body network system. It provides input/output status of each module.
4. If you will check each module data operation forcefully, select "Actuation test".
