Notes With Regard to Diagnosis

The phenomena listed in the following table are not abnormal.

Condition	Explanation
System check sound	When starting the engine, a thudding sound can sometimes be heard coming from inside the engine compartment. This is because the system operation check is being performed.
ABS operation sound	Sound of the motor inside the ABS hydraulic unit operation (whine). Sound is 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: tires)
ABS operation (Long braking distance)	For road surfaces such as snow-covered 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.

Inspection method

With the IGN OFF, set the IGN to ON position: If the ABS/Brake Warning Light illuminates and distinguishes after 3 seconds, the warning lamp and ABS system are all normal.

If the Warning Light does not illuminate when IGN is set to ON position
1. Remove the ABS ECU connector (located in the engine room).
2. Set the IGN to ON position.
3. If the ABS/Brake Warning Light does not illuminate: The failure is related to the Warning Light. Check the instrument cluster and wiring.
4. If the ABS/Brake Warning Light illuminates and stays on:
  The Warning Light is normal and judged to be failure of the VDC system. Inspect the VDC system using diagnostic tool.
If the Warning Light does not distinguish after its illumination when IGN is set to ON position.
1. Self-diagnose using diagnostic tool.
2. Record fault code.
3. Self-diagnose after erasing the fault code.
4. If the result of self-diagnosis is normal after erasing the fault code:
  Set the IGN to OFF, then to ON position and check whether the Warning Light operates normally.
5. If the result of self-diagnosis continues to display error after erasing the fault code:
  Check according to the inspection sheet of the fault code.
Even if the Warning Light and VDC system are all normal, erase all the memorized fault codes using diagnostic tool (if there is no memorized fault code, record the fault code).
CAUTION:
1. When removing or engaging all the connectors set the IGN to OFF position.
2. During the driving test, record on the inspection sheet when the Warning Light illuminates or every time any event is occurred.
