TROUBLESHOOTING
DIAGNOSIS TROUBLESHOOTING FLOW
Refer to GROUP 00 - How to Use Troubleshooting/Inspection
Service Point.
NOTE
If the engine-ECU is replaced, the immobilizer-ECU and
ignition key should be replaced together with it.
DIAGNOSIS FUNCTION
ENGINE WARNING LAMP (CHECK ENGINE LAMP)
If an abnormality occurs in any of the following items related
to the MPI system, the engine warning lamp will illuminate
or flash. If the lamp remains illuminated or if the lamp
illuminates while the engine is running, check the diagnosis
code output.
However, the warning lamp will illuminate as bulb check for
5 seconds whenever the ignition switch is turned to the ON
position.
