MIL flashing: there is a malfunction that could damage the Three Way
Catalytic Converter (TWC). In this case, drive only with reduced
power. MIL continuously on: there is a malfunction that degrades emissions.
Check DTC memory of the Engine Control Module (ECM) or the TCM. If there are driveability problems (e.g. a customer complaint) and the
MIL is not on, perform the MIL functional because malfunctions can be
stored that do not switch the MIL on.
