1. Turn the ignition switch to LOCK (0).
2. Release the connector clamp (A), then disconnect the wheel speed sensor connector (B).
3. Remove the clips, the bolt, and the wheel speed sensor (C).
4. Install the wheel speed sensor in the reverse order of removal, and note these items:  Install the sensor carefully to avoid twisting the wires.
 If the wheel speed sensor comes in contact with the wheel bearing, it is faulty. Investigate the cause beforereplacing the sensor.
5. Start the engine, and make sure the ABS indicator goes off.
6. Test-drive the vehicle, and make sure the ABS indicator does not come on.

4. Apply multi-purpose grease to the wheel speedsensor O-ring (A) and the sensor hole in the knuckle
(B).
5. Insert the guide pin tool (A) into the wheel speed sensor bolt hole until the shoulder of the tool
contacts the wheel speed sensor bracket.
NOTE: To prevent O-ring damage, the wheel speed
sensor must be installed with the guide pin tool. 6. Insert the wheel speed sensor (A) and the guide pin
tool (B) into the bolt hole on the knuckle.
NOTE: To ensure proper alignment when pushing
the wheel speed sensor into the knuckle housing,
do not hold the sensor bracket during installation,
hold the sensor wire.
7. Gently push and pull the wheel speed sensor in and out to make sure the O-ring is sliding properly in its
housing. While you are doing this, make sure the
sensor doesn’t come out of the knuckle assembly. If
the sliding effort is too high, remove the wheel
speed sensor, inspect the O-ring for damage, and
start the installation process again.
8. Remove the guide pin tool, then install the bolt, and tighten it to specified torque.
9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front
wheel.
10. Start the engine, and make sure the ABS indicators go off.
11. Test-drive the vehicle, and make sure the ABS indicators do not come on.

General Troubleshooting Information
A
D B
C
This system has four indicators:
 ABS indicator (A)
 Brake system indicator (B)
 VSA indicator (C)
 VSA activation indicator (D)
When the system is OK, each indicator comes on for
about 2 seconds after turning the ignition switch to
ON (II), then goes off.
When the system detects a problem, a DTC is set and,
depending upon the failure, the VSA modulator-control
unit determines which indicator(s) are turned on. If the
problem goes away (system returns to normal), the
indicator(s) are controlled in the following way
depending upon the DTC that is set:  The indicator(s) come on and stay on when the ignition switch is ON (II).
 The indicator(s) automatically go off.
 The indicator(s) go off after the vehicle is driven. The ABS indicator comes on when the ABS function is
lost. The brakes still work like a conventional system.
The brake system indicator comes on when the EBD
function is lost, the parking brake is applied, and/or the
brake fluid level is low.
NOTE: If two or more wheel speed sensors fail, the
brake system indicator comes on.
The VSA indicator comes on when the VSA function is
lost.
The VSA activation indicator blinks when the VSA
function is activating. The VSA activation indicator
comes on and stays on when the VSA is turned OFF by
using the VSA OFF switch, or when the VSA function is
lost.

VSA System Components
General Troubleshooting Information (cont’d)
 The memory holds all DTCs. However, when the
same DTC is detected more than once, the more
recent DTC is written over the earlier one. Therefore,
when the same problem is detected repeatedly, it is
memorized as a single DTC.
 The DTCs are indicated in the order they occur.
 The DTCs are memorized in the EEPROM. Therefore, the memorized DTCs cannot be erased by
disconnecting the battery. Do the specified
procedures to clear the DTCs.
 Self-diagnosis can be classified into two categories: – Initial diagnosis: Done right after the ignition switch is turned to ON (II) and until the ABS and VSA
indicators go off.
– Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to
LOCK (0).
 When the system detects a problem, the VSA modulator-control unit shifts to fail-safe mode.
The pump motor operates when the VSA modulator-
control unit is functioning, and the fluid in the reservoir
is forced out to the master cylinder, causing kickback at
the brake pedal.  The pump motor operates when the VSA modulator- control unit is functioning.
 The VSA modulator-control unit checks the pump motor operation one time after completing initial
diagnosis during regular diagnosis when the vehicle
is driven over 15 km/h (10 mph).
Brake fluid replacement and air bleeding procedures
are identical to the procedures used on vehicles without
the VSA system (see page 19-9). The troubleshooting procedures assume that the cause
of the problem is still present, and the ABS and/or VSA
indicator is still on. Following a troubleshooting
procedure for a code that has been cleared but does not
reset can result in incorrect diagnosis.
1. Question the client about the conditions when the problem occurred, and try to reproduce the same
conditions for troubleshooting. Find out when the
ABS and/or VSA indicator came on, such as during
activation, after activation, when the vehicle was
traveling at a certain speed, etc. If necessary, have
the client demonstrate the concern.
2. When the ABS or VSA indicator does not come on during the test-drive, check for loose connectors,
poor contact of the terminals, etc. in the circuit
indicated by the DTC before you start
troubleshooting.
3. After troubleshooting, or the repairs are done, clear the DTCs, and test-drive the vehicle under the same
conditions that originally set the DTCs. Make sure
the ABS and VSA indicators do not come on.
4. Check for DTCs from other systems which are connected via F-CAN. If there are DTCs that are
related to F-CAN, one possible cause was that the
ignition switch was turned to ON (II) with the VSA
modulator-control unit connector disconnected.
Clear the DTCs. Check for fuel and emissions DTC’s
first.
NOTE: Always troubleshoot fuel and emissions
DTC’s first.
The term ‘‘intermittent failure’’ means a system may
have had a failure, but it checks OK now. If you cannot
reproduce the condition, check for loose connectors or
terminal pins related to the circuit that you are
troubleshooting.

Symptom Troubleshooting Index
When the vehicle has one of these symptoms, check for VSA diagnostic trouble codes (DTCs) with the HDS. If there
are no DTCs, do the diagnostic procedure for the symptom, in the sequence listed, until you find the cause.
HDS does not communicate with the VSA modulator-
control unit or the vehicle Troubleshoot the DLC circuit (see page 11-204).
VSA activation indicator does not come on at start-up
(bulb check) 1.
2.Do the gauge control module troubleshooting
(see page 22-241).
Substitute a known-good VSA modulator-control unit,
then recheck. If it is OK, replace the original VSA
modulator-control unit (see page 19-171).
VSA activation indicator does not go off, and no DTCs
are stored 1.
2.Symptom Troubleshooting (see page 19-165).
Substitute a known-good VSA modulator-control unit,
then recheck. If it is OK, replace the original VSA
modulator-control unit (see page 19-171).
ABS indicator, brake system indicator, and VSA
indicator do not come on 1.
2.Do the gauge control module troubleshooting
(see page 22-241).
Substitute a known-good VSA modulator-control unit,
then recheck. If it is OK, replace the original VSA
modulator-control unit (see page 19-171).
ABS indicator, brake system indicator, and VSA
indicator do not go off 1.
2.
3.Check for F-CAN DTCs, and troubleshoot and repair
those first.
Do the gauge control module troubleshooting
(see page 22-241).
