STEP 8. Check steering wheel sensor output
voltage.
(1) Connect steering wheel sensor connector C-230.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage, by backprobing, between
terminal 1 and earth, terminal 4 and earth, and
terminal 5 and earth.
OK: The voltage should measure as indi-
cated in the figure.
Q: Is the steering wheel sensor output voltage
normal?
YES :
Go to Step 9.
NO :
Replace the steering wheel sensor (Refer to
). Then go to Step 11.
STEP 9. Check the following connectors.
•
Steering wheel sensor connector C-230
•
Intermediate connector C-138
•
ABS-ECU connector B-118
Check the connectors for loose, corroded or dam-
aged terminals, or terminals pushed back in the con-
nector.
Q: Are the connectors and terminals in good
condition?
YES :
Go to Step 10.
NO :
Repair it and then go to Step 11.

STEP 10. Check the following harness wires.
•
If diagnosis code No.81 (ST-1) is set: The wire
between steering wheel sensor connector C-230
(terminal 5) and ABS-ECU connector B-118 (ter-
minal 26)
• If diagnosis code No.82 (ST-2) is set: The wire
between steering wheel sensor connector C-230
(terminal 4) and ABS-ECU connector B-118 (ter-
minal 17)
• If diagnosis code No.83 (ST-N) is set: The wire
between steering wheel sensor connector C-230
(terminal 1) and ABS-ECU connector B-118 (ter-
minal 4)
Q: Is any harness wire damaged?
YES :
Repair or replace it and then go to Step 11.
NO :
Replace the brake modulator hydraulic unit
(integrated with ABS-ECU) (Refer to
). Then go to Step 11.
STEP 11. Check whether the diagnosis code is
reset.
Check again if the diagnosis code is set.
(1) Turn the ignition switch to the "ON" position.
(2) Erase the diagnosis code.
(3) Turn the ignition switch to the "LOCK" (OFF)
position.
(4) Turn the ignition switch to the "ON" position.
(5) Check if the diagnosis code is set.
(6) Turn the ignition switch to the "LOCK" (OFF)
position.
Q: Does diagnosis code No.81, 82 and/or 83 reset?
YES :
Return to Step 1.
NO :
The procedure is complete.

INSPECTION CHART FOR TROUBLE
SYMPTOMS
M1352011400750
NOTE: If steering movements are made when driv-
ing at high speed, or when driving on road surfaces
with low frictional resistance, or when passing over
bumps, the ABS may operate although sudden brak-
ing is not being applied. Because of this, when get-
ting information from the customer, check if the
problem occurred while driving under such condi-
tions as these.
NOTE: During ABS operation, the brake pedal may
vibrate a little or may not be able to be pressed. Such
conditions are due to intermittent changes in hydrau-
lic pressure inside the brake line to prevent the
wheels from locking. This is normal.
