PRECAUTIONS FOR DIAGNOSIS
NLBR0178S01
I
Before performing diagnosis, always read precautions. Refer
to BR-7.
I
If ABS actuator and electric unit (control unit), steering angle
sensor, steering system parts, suspension system parts, or
tires have been replaced, or if alignment has been adjusted, be
sure to adjust neutral position of steering angle sensor before
driving. Refer to BR-82.
I
After diagnosis is finished, be sure to erase memory. Refer to
GI-35.
I
When checking continuity and voltage between units, be sure
to check for disconnection, looseness, bend, or collapse of
connector terminals. If any malfunction is found, repair or
replace connector terminals.
I
For intermittent symptoms, possible cause is malfunction in
harness, harness connector, or terminals. Move harness, har-
ness connector, and terminals to check for poor connections.
I
If a circuit tester is used for the check, be careful not to forc-
ibly extend any connector terminal.
I
To use CONSULT-II to perform self-diagnosis of ABS actuator
and electric unit (control unit), active tests, or work support,

first stop work, then connect CONSULT-II and select “ABS”.
I
While
self-diagnostic
results
of
CONSULT-II
shows
malfunction, if CONSULT-II active test is performed, an engine
system error may be indicated. In this case, start engine to
resume the normal screen.
I
ESP/TCS/ABS system electronically controls brake operation
and engine output. The following symptoms may be caused by
normal operations:
I
When CONSULT-II is used, ABS warning lamp, ESP OFF indi-
cator lamp, SLIP indicator lamp may be ON/OFF.
Symptom
Symptom description
Result
Motor operation noise
This is noise of motor inside ABS actuator and electric unit (control unit).
Slight noise may occur during ESP, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), the 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
ESP/TCS operation
(SLIP lamp blinking)
TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when downshifting, or
when fully depressing accelerator pedal.
Normal
Cancel the ESP/TCS
function for the inspec-
tion on a chassis dyna-
mometer.
For inspection of speedometer or other instruments, press ESP OFF SW
to turn ESP/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
result 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
above. Make sure that warning lamp does not illuminate.
ABS operation (Longer stop-
ping 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 accelera-
tion 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.

BASIC INSPECTION 1 BRAKE FLUID LEVEL, LEAKS,
AND BRAKE PADS
NLBR0179S01
1.
Check fluid level in the brake reservoir tank. If fluid level is low,
refill the brake fluid.
2.
Check the brake piping and around the ABS actuator and elec-
tric unit (control unit) for leaks. If leakage or seepage is found,
check the following items.
I
If ABS actuator and electric unit (control unit) connection is
loose, tighten the piping to the specified torque and make sure
there are no leaks.
I
If there is damage to the connection flare nut or ABS actuator
and electric unit (control unit) screw, replace the damaged part
and re-conduct the leak inspection to make sure there are no
leaks.
I
If there is leakage or seepage at any location other than ABS
actuator and electric unit (control unit) connection, wipe away
leakage or seepage with clean cloth. Then inspect again and
confirm the there is no leakage.
I
If there is leakage from ABS actuator and electric unit (control
unit), wipe away leakage or seepage with clean cloth. Then
inspect again. If there is leakage or seepage, replace ABS
actuator and electric unit (control unit).
CAUTION:
ABS actuator body cannot be disassembled.
3.
Check brake disc and pads. Refer to BR-28 in “Front Disc
Brake” and BR-34 in “Rear Disc Brake”.
BASIC INSPECTION 2 POWER SYSTEM TERMINAL
LOOSENESS AND BATTERY INSPECTION
NLBR0179S02
Make sure the battery positive cable, negative cable and ground
connection are not loose. If looseness is detected, tighten the pip-
ing to the specified torque. In addition, check the battery voltage to
make sure it has not dropped and the altimeter is normal.
BASIC INSPECTION 3 ABS WARNING LAMP, ESP OFF
INDICATOR LAMP, SLIP INDICATOR LAMP
INSPECTION
NLBR0179S03
1.
Check that ABS warning lamp, ESP OFF indicator lamp (when
ESP OFF switch is OFF), and SLIP indicator lamp turns ON
approximately 2 second when ignition switch is turned ON. If
they do not, check the ESP OFF indicator lamp and then ESP
OFF switch. Refer to BR-142. Check CAN communications.
Refer to BR-140. If there are no errors with ESP OFF switch
and CAN communication system, check ABS warning lamp,
ESP OFF indicator lamp, SLIP indicator lamp and combination
meter. Refer to EL-114.

2.
Make sure the lamp turns OFF approximately 2 second after
ignition switch is turned ON. If the lamp does not turn OFF,
conduct self-diagnosis.
3.
With engine running, make sure ESP OFF indicator lamp turns
ON and OFF when ESP OFF switch is turned ON and OFF. If
the indicator lamp status does not correspond to switch
operation, check ESP OFF switch system. Refer to BR-142.
4.
Make sure ABS warning lamp, ESP OFF indicator lamp, and
SLIP indicator lamp turns OFF 2 seconds after engine is
started. If ABS warning lamp, ESP OFF indicator lamp, and
SLIP indicator lamp have not turned off 10 seconds after
engine has been started, conduct self-diagnosis of ABS actua-
tor and electric unit (control unit).
5.
After conducting self-diagnosis, be sure to erase the error
memory. Refer to GI-35.
Inspection 1 Wheel Sensor System
NLBR0180
After using the CONSULT-II SELF-DIAG RESULTS to determine
positions of malfunctioning wheel sensor, check all areas to deter-
mine the component to be replaced.
CAUTION:
I
Do not measure the resistance value and also voltage
between sensor terminal with tester etc., because e sen-
sor is an active sensor.
I
Do not expand terminal of connector with a tester termi-
nal stick, when it does the inspection with the tester.
