Principle of Code Cycle
Diagnostic trouble codes are determined as shown below.

1. Code cycle break




The time between diagnostic trouble code cycles is 4.0 seconds (the time the buzzer is off).

2. Second digit of diagnostic trouble code (ones position)




The digit in the ones position of the diagnostic trouble code represents the number of times the buzzer sounds 0.4 second during one cycle.

3. First digit of diagnostic trouble code (tens position)




The digit in the tens position of the diagnostic trouble code represents the number of times the buzzer is on 1.2 seconds during one cycle.

It should also be noted that the light goes off for 1.6 seconds between the long and short pulses of the buzzer.
