Diagnostic Trouble Code (DTC)

If the CPU cannot be activated, or it fails, the EPS indicator comes on, but no EPS DTC is stored.
The memory can hold any number of DTCs. However, when the same DTC is detected more than once, the most recent DTC is written over the prior DTC, therefore only one occurrence is stored.
The DTCs are stored in the EEPROM (non-volatile memory) therefore the stored DTCs cannot be erased by disconnecting the 12 volt battery. Do the specified procedures to clear the DTCs.
