NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
It
Diagnosis code displayed
Read diagnosis code
(Refer to P.354.) Read diagnosis code
(Refer to P.35-4.)
Diagnosis code displayed
Read (and write down) all displayed
diagnosis codes and the service data
(lault duration and how many times
memories are erased). And erase
them. (Refer to P.35-5.)
lnspection chart for trouble symptoms
(Refer to P.35-14.)
Inspection chart for diagnosis codes
(Refer to P.35-6.)
Phenomenon Explanation of phenomenon
System check sound When starting the engine, a thudding sound can sometimes be heard coming from inskle
the engine companment, but this is because the system operation check is being
performed, and is not an abnormality.
ABS operation sound 1. Sound of the motor inside the ABS hydraulic unit operation (whine)
2. Sound is generatöd 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.
Diagnosis detection condition can vary depending on the diagnosis code.

DIAGNOSIS FUNCTION
DIAGNOSIS CODES CHECK
with the iluT-rr
Connect the MUT-II to the diagnosis connector, then check
diagnosis codes.
Caution
Turn the ignition switch off before connecting or discon-
necting the MUT-II.
Wlthout the MUT-II
1. Use the special tool to earth diagnosis connector terminal
No.1.
Tum the ignition switch to ON and then take a reading of
the diagnosis codes from the flashing of the ABS warning
lamp.
