How to display DTCs on the MID of the gauge control module

Enter the B-CAN System Diagnosis Test Mode 1 (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE 1 AND TEST MODE 2 (WITHOUT THE HDS)  ). While in Test Mode 1, the DTCs which have been detected and stored individually by various B-CAN (Body-controller Area Network) units will be shown one by one on the multi-information display when the communication between the MICU and the gauge control module is normal. To scroll through the DTCs, press the SEL/RESET button.
