How to display DTCs on the gauge control module (tach)




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 odometer/trip meter display when the communication between the MICU and the gauge control module (tach) is normal.
