DIAGNOSIS FUNCTION

ENGINE WARNING LAMP (CHECK
ENGINE LAMP)

AKC00024AB

Engine warning lamp
(check engine lamp)

When the abnormal condition occurs with respect to
the items of Multipoint Fuel Injection (MPI) system
shown in the table, the engine warning lamp will illu-
minate or flash. When the lamp remains illuminated
after the engine start, or when the lamp is illuminated
while the engine is running, check the diagnosis
code output. There are two methods for checking the
indicator lamp burn out: When the ignition switch is in
"ON" position, the indicator lamp is illuminated, and
then extinguished few seconds later. When the igni-
tion switch is in "ON" position and the engine starts,
the indicator lamp is extinguished.

NOTE: When the CVT-ECU detects malfunctions
related to the CVT, the engine warning lamp is also
illuminated.
