Gauge Control Module DTC Display: Notes

Set the multiplex in 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 Multiplex Integrated Control Unit (MICU) and the gauge control module are normal. To scroll through the DTCs, press the SELECT/RESET button beside the gauge control module.
