Before inspect rear wheel encoder, remove rear drive
shaft referring to “Rear Drive Shaft Disassembly and
Assembly: Rear in Section 3A in related manual”.
• Check encoder (1) for being crack, damaged or

deformed.

• Turn wheel and check if encoder rotation is free from

eccentricity and looseness.

• Check that no foreign material is attached.

If any faulty is found, repair or replace. Refer to “Rear
Wheel Hub Assembly Removal and Installation in
Section 2C in related manual”.

Rear Wheel Encoder Removal and Installation

S5JB0E4506014

CAUTION

!

Rear wheel encoder is included in rear wheel
hub assembly. If rear wheel encoder needs to
replaced, replace it as a rear wheel hub
assembly.

Precautions

Precautions in Diagnosing Troubles

S5JB0E4600001

To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow
“Electronic Stability Program Check”.
• Diagnostic information stored in ESP

® control module

memory can be cleared as well as checked by using
SUZUKI scan tool. Before using 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 read “Precaution for CAN Communication

System in Section 00 in related manual” before
inspection and observe what is written there.

• Be sure to use the trouble diagnosis procedure as

described in “Electronic Stability Program Check”.
Failure to follow it may result 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 up lock lever (2) of connector.
When connecting, set the connector on ESP

®

hydraulic unit / control module assembly and pull
down the lock lever (2) until it locks.

• Communication of ECM, TCM (for A/T model), BCM,

ESP

® (ABS) control module (if equipped), 4WD

control module (if equipped), keyless start control
module (if equipped), combination meter and steering
angle sensor is established by CAN (Controller Area
Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00 in
related manual” before inspection and handling CAN
communication line.

Precautions in On-Vehicle Service

S5JB0E4600002

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 Check

S5JB0E4600003

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 “Hydraulic Unit Operation Check in
Section 4E” should be performed to confirm the correct
brake pipe connection in the following cases.
• ESP

® hydraulic unit / control module assembly was

replaced.

• Brake pipe and/or hose were replaced.

[A]: Disconnect

C: Pull up to disconnect

[B]: Connect

D: Pull down to connect
