Caterpillar 320/320GC/323 Fault Code Parameters
This blog mainly describes the alarm code information of Carter's latest model 320/320GC/323. Since the previous 320D document has already explained the composition of the fault code, I will not repeat it now. Friends who are interested or do not understand can refer to the document I sent earlier.
