Circuit Tests: Notes

NOTE: For component location information, see THEORY/OPERATION article.
CAUTION: If ECM replacement is instructed in following testing, always ensure ECM harness connector and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction. Ensure DTCs are diagnosed in numerical order, starting with lowest number first.
