Gauge Control Module DTC DisplayHow to display DTCs on the gauge control module
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 switch on the gauge control module.
The unit that has been stored the code can be identified by the number shown on the multi-information display.
How to clear the DTC
