NOTES WITH REGARD TO DIAGNOSIS
M1355009500016
1. The TCL/ASC is a system which controls the
brake pressure and engine power by means of
the operation of the ECU. Accordingly, the
following symptoms may occur at times, but these
are a sign of normal TCL/ASC operation, and do
not indicate 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.
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 TCL/ASC 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.
