Quizplus · Accepted Answer

The correct method to read flash codes on an OBD I Chrysler-built vehicle is by turning the ignition key on and off three times within five seconds, ending with the key in the "on" position. This process triggers the vehicle's self-diagnostic mode, which then flashes the check engine light in a sequence to indicate any stored trouble codes.
