ABSTRACT:
An electronic control unit and a method of diagnosing an electronic control unit on a vehicle are provided. The method includes the steps of storing in memory information on variables to collect, selecting a trigger, monitoring for a predetermined event, activating the trigger based on the detection of the event, collecting the variables upon activation of the trigger, and storing the collected variables in memory. The collected variable may be read via a pre-existing production serial link to diagnose the electronic control unit.
