Clearing the Fault Codes

The second item on the menu the EVO control module will output to the Star Tester is DTC 23. This represents asking the service technician whether he/she would like to "Clear fault codes?" stored in memory. If the service technician releases the HOLD/TEST button for one second, then latches the HOLD/TEST button down again within eight seconds after receiving DTC 23, the EVO control module will enter this test, clear the fault DTCs and complete this test by outputting DTC 24 to the Star Tester which means DTCs cleared.
