Using the HDS (Preferred Method)
Connect the HDS to the Data Link Connector (DLC).
NOTE:
There are two ways to read B-CAN code with the HDS.
First method; On the HDS, first select BODY ELECTRICAL, then select the subsystem that relates to the problem (for example: door locks, keyless, security, etc.), and then last, select the DTCs.
Second method; Ground the SCS circuit with the HDS, then read the DTCs displayed in the multi-information display (MID) in the gauge control module, then go to B-CAN SYSTEM DIAGNOSIS TEST MODE A .
