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

DTC ClearanceS7RS0B4504006
WARNING!
When performing a driving test, select a safe
place where there is neither any traffic nor
any traffic accident possibility and be very
careful during testing to avoid occurrence of
an accident.

After repair or replace malfunction part(s), clear all DTCs
by performing the following procedure or using SUZUKI
scan tool.
1) Connect SUZUKI scan tool to data link connector in the same manner as when making this connection
for DTC check.
2) Turn ignition switch to ON position.
3) Erase DTC according to instructions displayed on scan tool. Refer to scan tool operator’s manual for
further derails.
NOTE
For DTC C 1021, C1022, C1025, C1026, C1031,
C1032, C1035, C1036 and C1061, confirm that
ABS warning light turns off after performing
Step 2 of “Test Driving” under “ABS Check”,
and then clear the DTCs.

4) After completing the clear ance, turn ignition switch
OFF and disconnect scan tool from data link
connector.
5) Perform “Driving Test” (S tep 2 of “ABS Check”) and
“DTC Check” and confirm that NO DTC is displayed
on scan tool.
Scan Tool DataS7RS0B4504007
The parameter data below are values measured with the
scan tool when the normally operating vehicle is under
the following conditions. When taking measurements for
comparison by using the scan tool, be sure to check that
the vehicle is under the following conditions.
• Apply parking brake and block wheels.
• Ignition switch ON.
• Turn OFF air conditioner (if equipped).
• Apply no load to power steering (if equipped). (Don’t turn it)
• Turn OFF all electric loads (except ignition).
• No DTC.
• ABS is not operated. (N ormal braking operation)
Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ABS control module. Certain ABS
control module function s will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Driver (V): This parameter indicates the
operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LF Wheel Speed (km/h, MPH): Wheel speed
is an ABS control module inte rnal parameter. It is
computed by reference pulses from the wheel speed
sensor.
Brake Switch (ON, OFF): This switch signal informs
the ABS control modu le whether the brake is active
or not.

ABS Warning Light Does Not Come ON at Ignition Switch ONS7RS0B4504008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS contro l module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS control module turns ABS warning light ON at the ignition switch
ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS warning light is
turned ON continuously by ABS control module. Also, it is turned ON continuously by la mp driver module when the
connector of ABS control module is disconnected.
