For Fast and Accurate Diagnosis

PRECAUTIONS FOR DIAGNOSIS
●
Before performing diagnosis, always read precautions. Refer to
.
●
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
BRC-49, "Adjustment of Steering Angle Sensor
●
After diagnosis is finished, be sure to erase memory. Refer to
●
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 termi-
nals.
●
For intermittent symptoms, possible cause is malfunction 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 careful not to forcibly extend any connector terminal.
●
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”.
●
While self-diagnosis 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.
●
VDC/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
●
When CONSULT-II is used, ABS warning lamp, VDC OFF indicator 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 VDC, 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 IGN (igni-
tion) 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 compart-
ment. This is normal and is part of system operation check.
Normal
VDC/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 VDC/TCS
function for the inspec-
tion on a chassis dyna-
mometer.
For inspection of speedometer or other instruments, press VDC OFF SW
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
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. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.
Normal
Insufficient feeling of acceler-
ation
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.

Basic Inspection
NFS000GK
BRAKE FLUID LEVEL, LEAKS, AND BRAKE PADS
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 electric unit (control unit) for leaks. If leakage or
seepage is found, check the following items.
●
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.
●
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.
●
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 on leakage.
●
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 and electric unit (control unit) body can not be disassembled.
3.
Check brake disc and pads. Refer to
BR-26, "Removal and Installation of Brake Pad"
in “Front Disc
Brake” and
BR-32, "Removal and Installation of Brake Pad"
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY
Make sure the battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the piping to the specified torquer. In addition, check the battery voltage to make sure it has
not dropped and the altimeter is normal.
