TROUBLESHOOTING35201110129
STANDARD FOW 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.
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.
DIAGNOSIS FUNCTION 35201120106
DIAGNOSIS CODES CHECK
Read a diagnosis code by the MUT-II or ABS
warning lamp. (Refer to GROUP 00 – How to Use
Troubleshooting/Inspection Service Points.)
ERASING DIAGNOSIS CODES

Remedy the malfunctions indicated by th
diagnosis codes, disconnect the diagnosis code
check harness, and then install the valve relay.
Then turn the ignition switch to ON again t
check the ABS warning lamp. (Refer to P.35-36-
16.) If the lamp indicates a malfunction, th
valve relay system may be detective. (Refer to
P.35-36-14.)
ERASING DIAGNOSIS CODES
With the MUT-II
Connect the MUT-II to the diagnosis connector (16-
pin), and then erase the diagnosis codes.
Without the MUT-II
Remove the battery cable from the battery (-)
terminal for 10 seconds or more, and the
reconnect the cable.

shooting/Inspection Service Points.)
ERASING DIAGNOSIS CODES
With the MUT-II
Refer to GROUP 00 – How to Use
Troubleshooting/Inspection Service Points

When diagnostic trouble codes (Nos. 21 to 24) (for vehicle wheel speed sensor system failures) occur,
normal MUT-II operation may not erase those codes. In that case, erase the diagnostic trouble codes
using the following procedures.
1.
Perform erasing of the diagnostic trouble codes by special operation of the brake pedal. (See erasing
procedure for the diagnostic trouble codes without use of the MUT-II.)
2.
Turn the ignition switch OFF.
3.
Perform erasing of the diagnostic trouble codes by use of the MUT-II.

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 (initial check at
a vehicle speed of 8 km/h), and does not indicate any malfunction.
