Diagnosis By “ABS” Warning Light
Illumination Pattern

In the event that there is abnormality in the “ABS” warning
light illumination pattern while the key is in the ON position
or if the warning light is actuated while driving, refer to the
flow chart below for the correct diagnostic procedure.

No.

Warning light goes at
12 km/h (8 mph) or
higher (After repairing
the faulty part)

Even after repairing the
faulty part the warning light
(W/L) dose not go out if
vehicle is at a stop.
Turn the ignition switch to the
ON position and drive the
vehicle at 12 km/h (8 mph) or
higher to make sure that the
warning light goes out.

Diagnostic Trouble Codes (DTCs)

When the warning light in the meter remains ON, the
EHCU stores the fault identification and disables the
ABS.
How to display and erase DTCs:

NOTE:

D

DTCs can be displayed also by TECH 2. Use
“Diagnostic Trouble Codes” mode.

1. How to start DTC display:

D

Confirm that the vehicle has come to a complete
stop (with the wheels standing still) and that the
brake pedal is not depressed.  (Unless these two
condition are satisfied, DTC display cannot be
started.)

D

With IGN OFF, connect #12 terminal with #4
terminal or # 5 terminal (GND) . Then turn IGN ON.

The DLC is located behind the driver side kick panel

350R200001

D

Keep #12 terminal connected with #4 terminal or # 5
terminal (GND) during DTC display. (If #12 terminal
is separated from #4 terminal or # 5 terminal (GND)
during display, display will stop.)

2. DTC display:

D

DTC is displayed by blinking warning light.

D

Double-digit display.

D

First, normal DTC 12 is displayed three times and
then any other DTCs are displayed three times.  (If
no other DTCs have been stored, the display of DTC
12 will be repeated.)

3. How to erase code:

D

Conduct brake switch ON/OFF operation 6 or more
times within 3 seconds of self-diagnosis startup.

D

The code cannot be erased if more than 3 seconds
have passed since self-diagnosis startup, or if
self-diagnosis has started with brake switched on
(brake pedaled).
