Use rubber grease whose viscosity varies
very little even at –40

°C (–40 °F) if applied.

2) Tighten caliper pin bolts to specified torque.

NOTE
Make sure that boots are fit into groove
securely.

Tightening torque
Caliper pin bolt: 36 N·m (3.6 kgf-m, 26.0 lb-ft)

3) Install brake flexible hose as shown and tighten

flexible hose joint bolt (1) to specified torque.

Tightening torque
Flexible hose joint bolt (a): 23 N·m (2.3 kgf-m,
17.0 lb-ft)

Precautions

Precautions in Diagnosing Troubles

S5JB0E4500001

To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS (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, ABS warning lamp may light momentarily but
this does not indicate anything abnormal in ABS.
– 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 “ABS Check”. Failure to follow it may
result in incorrect diagnosis. (Some other diagnosis
trouble code may be stored by mistake in the memory
of ABS (ESP

®) control module during inspection.)

• When disconnecting ABS hydraulic unit / control

module connector (1), pull down lock lever (2) of
connector.
When connecting, set the connector on ABS hydraulic
unit / control module assembly and pull up the lock
lever (2) until it locks.

• When disconnecting ESP

® hydraulic unit / 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,

ABS (ESP

®) control module (if equipped), 4WD

control module (if equipped), keyless start control
module (if equipped), steering angle sensor (if
equipped) and combination meter 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 handle CAN
communication line.

Precautions in On-Vehicle Service

S5JB0E4500002

When connector is connected to ABS (ESP

®) hydraulic

unit / control module assembly, do not disconnect
connectors of sensors with ignition switch ON.
Otherwise, DTC will be set in ABS (ESP

®) control

module.

Precautions in Hydraulic Unit Operation Check

S5JB0E4500003

ABS (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” should be performed to confirm the
correct brake pipe connection in the following cases.
• ABS (ESP

®) hydraulic unit / control module assembly

was replaced.

• Brake pipe and/or hose were replaced.
