Recalling Trouble Codes

The ECM stores component failure information under related trouble codes which can be recalled for diagnosis and repair. When recalled, these codes will be displayed by flashes of the "CHECK ENGINE" light. Codes are displayed starting with the lowest numbered code. Only codes in which a related malfunction has occurred will be displayed.

Codes are called out by flashes of the "CHECK ENGINE" light. For example, "FLASH", "FLASH", "FLASH", pause, "FLASH", "FLASH", followed by a longer pause, identifies trouble code "32". First series of flashes indicates first digit of trouble code; second series of flashes indicates second digit of trouble code.
