DTC) again 5 seconds after the single digit indicator turns off. The ten digit and single digit indicators
remain on for 3 seconds at the same time after the single digit indicator goes off for 2 seconds, which
indicates self-diagnosis is completed and it has exited the system (power on or turn on/off A/C
