Integrated Circuit Module (ICM) Relay Unit Repair Procedures

Inspection

1. 1
   The ICM (Integrated Circuit Module) can be diagnosed using GDS. The BCM communicates with GDS, then reads the relay value and operates the actuator.
2. 2
   To diagnose the ICM relay function, select the vehicle model and the body control module from the menu.
3. 3
   Select "Input/Output Control" to check the current data of the body network system. It provides the input/output status of each module.
4. 4
   If you are going to forcibly check each module data operation, select "Active Test".
