 When active test is performed while depressing, t he pedal depression amount will change. This is normal.
 “TEST IS STOPPED” is displayed 10 seconds after operation start.
 After “TEST IS STOPPED” is displayed, touch “BACK” and perform test again.
TEST ITEM
Solenoid Valve
NOTE:
The example shown is for the front right wheel. The procedure for the other wheels is the same as given
below.
 When performing an active test of the ABS function, se lect the main item for each test item. In addition,
when performing an active test of the VDC/TCS function, select the item menu for each test item.
 For the ABS solenoid valve, touch “UP” “KEEP” “DOWN”, and for the ABS solenoid valve (ACT), touch “UP”
“ACTUATOR UP” “ACTUATOR KEEP”, and check to make su re that all solenoid valve (in, out) are operating
as given in the table below.
*: ON for 1 to 2 seconds after the touch, and then OFF
ABS Motor
Touch “ON” and “OFF” on the screen. Make sure AB S motor relay operates as shown in table below.

PRECAUTIONS FOR DIAGNOSIS
 Before performing diagnosis, always read precautions. Refer to BRC-13, "How to Proceed with Diagnosis".
 If ABS actuator and electric unit (control unit), steer ing angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-8, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion".
 After diagnosis is finished, be sure to erase memory. Refer to BRC-26, "
Self-Diagnosis".
 When checking continuity and voltage between units, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfuncti on is found, repair or replace connector terminals.
 For intermittent symptoms, possible cause is malfunc tion in harness, harness connector, or terminals. Move
harness, harness connector, and terminals to check for poor connections.
 If a circuit tester is used for the check, be ca reful not to forcibly extend any connector terminal.
 To use CONSULT-III to perform self-diagnosis of ABS act uator and electric unit (control unit), active tests, or
work support, first stop work, then connect CONSULT-III and select “ABS”.
 While self-diagnostic results of CONSULT-III shows malf unction, if CONSULT-III active test is performed, an
engine system error may be indicated. In this case, start engine to resume the normal screen.
 VDC/TCS/ABS system electronica lly controls brake operation and engine output. The following symptoms
may be caused by normal operations:

TROUBLE DIAGNOSIS
Basic Inspection
INFOID:0000000001327676
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake piping and around ABS actuator and electric uni t (control unit) for leaks. If there is leaking or
oozing fluid, check the following items.
 If ABS actuator and electric unit (control unit) connec tion is loose, tighten piping to the specified torque
and re-perform the leak inspection to make sure there are no leaks.
 If there is damage to the connection flare nut or AB S actuator and electric unit (control unit) screw,
replace the damaged part and re-perform the leak inspection to make sure there are no leaks.
 When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if fluid is just oozing out, use a clean cl oth to wipe off the oozing fluid and re-check for leaks.
If fluid is still oozing out, replace the damaged part.
 When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if fluid is just oozing
out, use a clean cloth to wipe off oozing fluid and re-che ck for leaks. If fluid is still oozing out, replace
ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (contr ol unit) body can not be disassembled.
3. Check brake pad degree of wear. Refer to BR-18, "
On-Vehicle Inspection" in “Front Disc Brake” and BR-
24, "On-Vehicle Inspection" in “Rear Disc Brake”
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cabl e and ground connection are not loose. If looseness is
detected, tighten the cables. In additi on, check the battery voltage to make sure it has not dropped and alter-
nator is normal.
ABS WARNING LAMP, VDC OFF INDICATOR LAMP, SLIP INDICATOR LAMP AND BRAKE WARN-
ING LAMP INSPECTION
Symptom Symptom description Result
Motor operation noise This is noise of motor in
side ABS actuator and electr ic unit (control unit).
Slight noise may occur during VDC, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and valves
operating noise may be heard. It happens only once after ignition switch is
ON. This is a normal status of the system operation check.
System operation check noise When engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check. Normal
VDC/TCS operation
(SLIP indicator lamp blinking) TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when up/downshifting, or when ful-
ly depressing accelerator pedal.
Normal
Cancel the VDC/TCS
function for the inspec-
tion on a chassis dyna-
mometer.
For inspection of speedometer or other instruments, press VDC OFF switch
to turn VDC/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is re-
sult of TCS being activated by stationary front wheels. Warning lamp may
also illuminate to indicate “sensor system error”. This is also normal, and is
the result of the stationary front wheels being detected. To be certain, restart
engine, and drive vehicle at 30 km/h (19 MPH) or more. Make sure warning
lamp does not illuminate.
ABS operation
(Longer stopping distance) On roads with low friction coefficients, such as snowy roads or gravel roads,
vehicles with ABS may require a longer stopping distance. Therefore, when
driving on such roads, avoid overconfidence and keep speed sufficiently
low.
Normal
Insufficient feeling of accelera-
tion Depending on road conditions, driver may feel that feeling of acceleration is
insufficient. This is because traction control, which controls engine and
brakes to achieve optimal traction, has the highest priority (for safety). As a
result, there may be times when acceleration is slightly less than usual for
the same accelerator pedal operation.
Normal

Note 1:Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake fluid level switch
(brake fluid is insufficient).
Note 2:After starting engine, turn OFF.
1. Make sure ABS warning lamp, VDC OFF indicator lamp (when VDC OFF switch is OFF), and SLIP indica- tor lamp turn on approximately 2 second, and brake warning lamp turns on when ignition switch is turned
ON. If they do not, check VDC OFF indicator lamp and then VDC OFF switch. Refer to BRC-48, "
Compo-
nent Inspection". Check CAN communications. Refer to “CAN Communication Inspection”. If there are no
errors with VDC OFF switch and CAN communication system, check combination meter. Refer to DI-5
.
2. Make sure ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp turn off approximately 2 sec- ond after turn ignition switch ON, and brake warning lamp turns off after engine starts. If lamps do not turn
off, perform self-diagnosis.
3. With engine running, make sure VDC OFF indicator lamp turns on and off when VDC OFF switch is turned ON and OFF. If indicator lamp status does not correspond to switch operation, check the VDC OFF
switch system. Refer to BRC-48, "
Component Inspection".
4. Make sure ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off 2 seconds after engine is started. If ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp have not turned
off 10 seconds after engine has been started, perform self-diagnosis of ABS actuator and electric unit
(control unit).
5. After performing the self-diagnosis, be sure to erase the error memory. Refer to BRC-26, "
Self-Diagnosis".
NOTE:
Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid level
switch should not stay “ON” position.
