"CLEAR CODES?" Selection

Selecting the "CLEAR CODES?" test type will result in a "CLEAR CODES?" message display, along with the name of the system was being tested. This message will be displayed for 3 seconds to indicate that all stored trouble codes have been erased from system's memory. After 3 seconds, the display will automatically return to the next available test type for the selected system.
