Precautions
Precautions in Diagnosing TroublesS7RS0B4500001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS cont rol 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, ABS warning light 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 “Precautions for Electrical Circuit Service in Section 00” befo re 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 control module during inspection.)
• When disconnecting ABS co ntrol module connector
(1), pull down lock lever (2) of connector.
When connecting, set the connector on ABS control
module assembly and pull up the lock lever (2) until it
locks. • Communication of ECM,
BCM, ABS control module,
keyless start control module (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”
before inspection and handle CAN communication
line.
Precautions in On-Vehicle ServiceS7RS0B4500002
When connector is connected to ABS control module
assembly, do not disconnect connectors of sensors with
ignition switch ON. Otherwise, DTC will be set in ABS
control module.
Precautions in Hydraulic Unit Operation CheckS7RS0B4500003
ABS 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 “ABS Hydraulic Unit Operation Check”
should be performed to confirm the correct brake pipe
connection in the following cases.
• ABS hydraulic unit / cont rol module assembly was
replaced.
• Brake pipe and/or hose ware replaced.
[A]: Disconnect C: Pull down to disconnect
[B]: Connect D: Pull up to connect

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.
