Warning light check
1. Check if the warning light turns on with the ig-
nition switch set to ON, but with the engine stop-
ped.
2. Check if the warning light turns off when the en-
gine is started.
If the warning light remains on or flashing, the di-
agnosis system has detected an operation defect.
A failure code has been therefore stored in the
electronic control unit.
If no failure code has been stored in the electronic
control unit, check the warning light circuit.
N.B.
- IF THE WARNING LIGHT DOES NOT TURN ON, PERFORM
TROUBLESHOOTING ON THE INSTRUMENT PANEL.
Failure code check using the diagnostic tester
DS-21 or OBD II general scanning device

general scanning device.

diagnostic tester DS-21 or OBD II general scan-
ning device to the data link connector located at
the lower part of the driver side instrument panel.
Now, connect the diagnostic tester DS-21 to the
data link connector interposing the following spe-
cial tool, and connect the OBD II general tester
directly.
