Blink Code Function
Although the DST is considered a required tool to access the DTC codes, codes may be retrieved without a
laptop computer using the blink code function. To enable this function follow the steps below:
• Jump pins 1 and 4 at the DLC connector (see illustration below)
• Turn the ignition key to the on position
• The system will now enter the self diagnostic blink code mode. Be ready with pen and paper to write
down any codes that may be stored.
• The ECM will flash the MIL indicator with a pause between represented numbers that represent DTC
codes. The sequence starts with code 1654. Code 1654 confirms the system has entered the blink code
mode. The ECM will flash code 1654 (3) times before displaying the actual DTC code that may be set.
Example:
One short blink (pause) six short blinks (pause) five short blinks (pause) four short blinks.
• If no DTC codes are found, the ECM will continue to flash 1654 only. This means no stored DTC codes
were found.
• If one of the numbers in the DTC code is zero (0), no flash will occur to represent the zero value—it will be
represented as a short pause.
