Continuously lit:
There is a malfunction that causes increased
emissions. Check DTC memory for Motronic
ECM and automatic transmission (if installed).
Check DTC memory if there is a driveability
problem or a customer complaint, but the
Malfunction Indicator Lamp (MIL) is not lit. There
may be DTCs stored that do not cause the
exhaust MIL to light up immediately, but only
after engine is started again and malfunction is
recognized again.

Blinking:
There is a malfunction that causes damage to
the catalytic converter in this driving condition
(e.g. combustion misfire). In this case, vehicle
must only be driven at reduced power!

Note:
Catalytic converter must be checked after
malfunction is repaired.
