Retrieving Diagnostic Trouble Codes
The Check Engine light indicates a failure code by the length and number of blinks. The Check Engine light can indicate any number of simultaneous component problems by blinking separate codes, one after another. Problem codes 1 through 9 are indicated by individual short blinks. Problem codes 10 through 59 are indicated by a series of long and short blinks. The number of long blinks indicates the first digit and the number of short blinks indicates the second digit. See Fig 1 .
