When only 1 DTC is stored, the light outputs the same code after an interval of 4 seconds.
When 2 or more DTCs are stored, the light outputs the codes with an interval of 2.5 seconds between each different code, and the output of all codes repeats after an interval of 4 seconds.
When multiple codes are output, they are output in order of the lowest code number first.
