NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
Phenomenon Explanation of phenomenon
System check sound When starting the engine, a thudding sound can sometimes
be heard coming from inside the engine compartment, but
this is because the system operation check is being
performed, and is not an abnormality.
ABS operation sound Sound of the motor inside the ABS hydraulic unit operation.
(whine)
Sound is the generated along with vibration of the brak
pedal. (Scraping).
When ABS operates, sound is generated from the vehicle
chassis due to repeated brake application and release.
(Thump: suspension; squeak: tyres)
ABS operation (Long braking distance) 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 suc
roads by lowering the vehicle speed and not being too
overconfident.
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.
