STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
Refer to GROUP 00 ± How to Use Troubleshooting/Inspection Service Points.
NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
PhenomenonExplanation of phenomenon
System check soundWhen 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 sound1. Sound of the motor inside the ABS hydraulic unit operation. (whine)
2. Sound is the generated along with vibration of the brake pedal. (scraping)
3. 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 such roads by lowering the vehicle speed and not being too
overconfident.
Shock during system
operation checkShock may be felt when the brake pedal is depressed slightly at a low driving speed. This
occurs due to ABS operation check (check at a vehicle speed of 8 km/h after starting), and
does not indicate any malfunction.
Diagnosis detection condition can vary depending on the diagnosis code.
Make sure that checking requirements listed in the ªCommentº are satisfied when checking the trouble
symptom again.
