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.
