For codes on the Diagnostic Trouble Code Chart subject to "2 trip detection logic", perform the following actions. Turn the engine switch off after the symptom is simulated once. Then repeat the simulation process. When the symptom has been simulated twice, the MIL illuminates and the DTCs are recorded in the TCM.
