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 reed the DTCs displayed in the multi-information display (MID) in the gauge assembly, then go to B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A )
