DIAGNOSIS FUNCTION

M1131155504935

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.
