NOTES WITH REGARD TO DIAGNOSIS

M1352012600393

1. The ABS is a system which controls the brake

pressure by means of the operation of the ECU.
Accordingly, the following symptoms may occur at
times, but these are a sign of normal ABS
operation, and do not indicate a malfunction.

Phenomenon

Explanation of phenomenon

When the engine starts, a knocking sound can be heard coming
from the engine compartment.

This sound occurs as a result of system
operation checking, and is not a
malfunction.

• Sound of the motor inside the ABS hydraulic unit operation.

(whine)

• Sound is the generated along with vibration of the brake

pedal. (scraping)

• When ABS operates, sound is generated from the vehicle

chassis due to repeated brake application and release.
(Thump: suspension; squeak: tyres)

This is the sound of normal system
operation, and is not a malfunction.

Shocks are felt if the brake pedal is depressed when driving at
low speed.

This is due to system operation checking
(starting-of check when the vehicle speed
reaches a certain number of km/h) and is
not a malfunction.

2. For road surfaces such as snow-covered roads

and gravel roads, the braking distance for
vehicles with ABS can sometimes be longer than
that for other vehicles. Accordingly, advise the
customer to drive safely on such roads by
lowering the vehicle speed and not being too
overconfident.

3. Diagnosis detection condition can vary depending

on the diagnosis code. Make sure that checking
requirements listed in the "Comment" are satisfied
when checking the trouble symptom again.

ABS WARNING LAMP AND BRAKE
WARNING LAMP CHECK

M1352012001316

Check that ABS and brake warning lamps illuminate
as follows.

NOTE: The EBD warning lamp is also used as the
brake warning lamp.

NOTE:

•

: The ABS warning lamp may stay ON until the

vehicle speed reaches 10 km/h. As far as
ABS-ECU stores any diagnosis code related to
the wheel speed sensor malfunction or the motor
malfunction as past trouble, ABS-ECU continues
illuminating the ABS warning lamp until it verifies
that the malfunction for that code is resolved
(startup check).

•

: The brake warning lamp does not turn OFF

when the parking brake is applied or the brake
fluid level is lowered.

DIAGNOSTIC FUNCTION

M1352011201726

ABS-ECU has the following functions for easier sys-
tem checks. The following items can be diagnosed
using M.U.T-III.

• Diagnosis code set (Refer to

P.35B-11

• Service data output (Refer to

P.35B-54

• Actuator test (Refer to

P.35B-55

• Freeze frame data output (Refer to ).

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the
M.U.T.-III.

When detecting fault and storing the diagnosis code,
the ECU connected to CAN bus line obtains the data
before the determination of the diagnosis code and
the data when the diagnosis code is determined, and
then stores the ECU status of that time. By analysing
each data from M.U.T.-III, the troubleshooting can be
performed more efficiently. The displayed items are
as the table below.
