System check sound
TSB Revision
ABS operation soundSound of the motor inside the ABS hydraulic unit op erating (whine)2. Sound is generated along with vibration of the (scraping)
3.When ABS operates, sound is generated from the vehi cle chassis due to brake application and release.
(Thump: suspension; squeak: tires)
ABS operationFor road surfaces such as snow-covered roads and gravel roads, the braking distance for
(Long braking distance)vehicles with ABS can sometimes be longer than that for other Accordingly,
advise the customer to drive safely on such roads by lowering the vehicle speed

Diagnosis detection condition depends on the diagno stic trouble code.
