Diagnostic trouble code (DTC) information ECM-3502
Condition
If the engine control module (ECM) detects a particular number of misfires during a set number of crankshaft revolutions, this will be interpreted as misfires which increase emissions. The diagnostic trouble code (DTC) will be stored. In certain cases, the diagnostic trouble code (DTC) qualifier can also indicate which cylinder is misfiring.
The misfire diagnostic is active after the engine is started. Also see “Design and function, misfire diagnostic”.
