3) Turn over floor carpet (2) and disconnect connector (1) of wheel speed sensor.
4) Hoist vehicle and remove wheel.
5) Remove harness clamp (1) and clamp bolts (2).
6) Remove rear wheel speed sensor (3) from knuckle.
CAUTION!
• Do not pull wire harness when removing rear wheel speed sensor.
• Do not cause damage to surface of rear wheel speed sensor and do not allow dust,
etc. enter its installation hole.

Installation
Reverse removal procedure for installation noting the
following.
• Check that no foreign material is attached to sensor (1) and mating encoder (2).
• Be sure to install wheel speed sensor (1) and its bolt at the correct position as shown in figure.
Tighten sensor bolt and harness clamp bolts to
specified torque.
Tightening torque
Rear wheel speed sensor bolt (a): 11 N·m (1.1 kgf-
m, 8.0 lb-ft)
Rear wheel speed sensor harness clamp bolt (a):
11 N·m (1.1 kgf-m, 8.0 lb-ft)
CAUTION!

Precautions
Precautions in Diagnosing TroublesS7RS0B4600001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow
“Electronic Stability Program System Check”.
• Diagnostic information stored in ESP® control module
memory can be cleared as well as checked by using
SUZUKI scan tool. Before us ing scan tool, read its
Operator’s (Instruction) Manual carefully to have good
understanding as to what functions are available and
how to use it.
• If the vehicles was operated in any of the following ways, ESP ® warning lamp may light momentarily but
this does not indicate anything abnormal in ESP ®.
– The vehicle was driven with parking brake pulled.
– The vehicle was driven with brake dragging.
– The vehicle was stuck in mud, sand, etc.
– Wheel spin occurred while driving.
– Wheel(s) was rotated while the vehicle was jacked up.
• Be sure to use the trouble diagnosis procedure as described in “Electronic Stability Program System
Check”. Failure to follow it may resu lt in incorrect
diagnosis. (Some other diagnosis trouble code may
be stored by mistake in the memory of ESP ® control
module during inspection.)
• When disconnecting ESP ® control module connector
(1), pull down the lock lever (2) of connector.
When connecting, set the connector on ESP ®
hydraulic unit / control module assembly and pull up
the lock lever (2) until it locks. • Communication of ECM, BCM, ESP
® control module,
keyless start control module (if equipped), steering
angle sensor and combination meter is established by
CAN (Controller Area Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00”
before inspection and handling CAN communication
line.
Precautions in On-Vehicle ServiceS7RS0B4600002
When connector is connected to ESP ® hydraulic unit /
control module assembly, do not disconnect connectors
of sensors with ignition switch ON. Otherwise, DTC will
be set in ESP ® control module.
Precautions in Hydraulic Unit Operation CheckS7RS0B4600003
ESP® hydraulic unit / control module assembly function
is checked by correct wheel lock / release condition
when brake pressure is pressurized / depressurized
using SUZUKI scan tool. The hydraulic unit operation
check referring to “ESP ® Hydraulic Unit Operation
Check” should be performed to confirm the correct brake
pipe connection in the following cases.
• ESP® hydraulic unit / contro l module assembly was
replaced.
• Brake pipe and/or hose were replaced.
Precautions in Sensor CalibrationS7RS0B4600004
ESP ® control module stores calibration points data of yaw rate / G sensor assembly and master cylinder pressure
sensor. Steering angle sensor stores calibration point data of itself.
TCS and stability control system use these sets of data.
When the following operation is done, sensor calibration should be performed since the original calibration points are
deleted.

Circuit Description
EBD warning lamp (brake warning lamp) is controlled by ESP® control module and BCM through lamp driver module
in combination meter.
If EBD system is in good condition, ESP ® control module turns EBD warning lamp ON at the ignition switch ON,
keeps it ON for 2 seconds and then turns it OFF.
EBD warning lamp is turned ON cont inuously at the following conditions.
• EBD system is an abnormality
• Connector of ESP ® control module is disconnected
• Parking brake switch is ON
• Brake fluid level is lower than minimum level
The information of parking brake switch and brake fluid leve l are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
Troubleshooting
Step Action Yes No 1 Check parking brake and brake fluid level
1) Make sure that:
• Parking brake is completely released.
• Brake fluid level is upper than the minimum level.
Are the check results OK? Go to Step 2. Release parking brake
completely and/or
replenish brake fluid.
2 Check ABS warning lamp
1) Turn ignition switch to ON position.
Does ABS warning lamp come on steady? Perform “ABS Warning
Lamp Does Not Come
ON at Ignition Switch
ON” previously outlined.Go to Step 3.
3 Check parking brake switch circuit and brake fluid level
switch circuit
1) Release parking brake completely, and replenish brake
fluid.
2) Disconnect BCM connectors with ignition switch turned OFF.
3) Measure resistance between each terminal of “L01-6”, “E46-5” and vehicle body ground.
Are resistance
∞ Ω? Go to Step 4. Check each applicable
circuit for short to
vehicle body ground. If
OK, then check parking
brake switch and/or
brake fluid level switch.
4 CAN communication circuit check
1) CAN communication circuit between combination meter,
ABS (ESP® ) control module and BCM referring to “DTC
U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If EBD
warning lamp remains
ON, substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.

4 Check ECM circuit for stop lamp switch
1) Disconnect connectors from ECM.
2) Check for proper connection to “E23-20” wire of ECM
connector.
3) If connections are OK, check stop lamp switch circuit for
the following.
• Resistance of “GRN/WHT” wire terminal of stop lamp switch between stop lamp switch connector and ECM
connector is less than 1 Ω (continuity check)
• Resistance between “GRN/WHT” wire terminal of stop lamp switch connector and vehicle body ground is
infinity (ground short check)
• Voltage of between “GRN/WHT” wire terminal of stop switch connector and vehicle body ground is 0 V with
ignition switch tuned ON (power short check)
