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 TroubleshootingStep Action Yes No 1 Was “ABS Check” performed? Go to Step 2. Go to “ABS Check”.
2 1) Disconnect applicable ABS wheel speed sensor coupler with ignition switch OFF.
2) Measure resistance betw een terminals of ABS wheel
speed sensor. Refer to “Front Wheel Speed Sensor
Inspection” and/or “Front Wheel Encoder On-Vehicle
Inspection”.
Is measured resistance value as specified? Go to Step 3. Replace ABS wheel
speed sensor assembly.
3 1) Turn ignition switch OFF. 2) Connect applicable ABS wh eel speed sensor coupler.
3) Disconnect ABS hydraulic unit / control module connector.
4) Check for proper connection to ABS control module at each sensor terminal.
5) If OK, then turn ignition switch ON and measure voltage between applicable sensor terminal of module connector
and body ground.
Is it 0 V? Go to Step 4. ABS wheel speed
sensor circuit shorted to
power.
4 1) Turn ignition switch OFF. 2) Measure resistance between the following points.• Both ABS hydraulic unit / control module connector terminals of the correspo nding sensor. This check
result should be the same as Step 2).
• Either terminal of wheel speed sensor coupler and body ground. This check result should be no
continuity.
Are both check results OK? Go to Step 5. Circuit open or shorted
to ground.
5 1) Remove applicable ABS wheel speed sensor. 2) Check sensor for damage or foreign material attached.
Is it in good condition? Go to Step 6. Clean, repair or replace.
6 Check front and/or rear sensor ring for the following (remove rear drum as necessary):
• Sensor ring serration (teeth) neither missing nor damaged
• No foreign material being attached
• Sensor ring not being eccentric
• Wheel bearing free from excessive play
Are they in good condition? Go to Step 7. Clean, repair or replace.
7 1) Install ABS wheel speed sensor to knuckle. 2) Tighten sensor bolt to specified torque and check that there is no clearance between sensor and knuckle.
Is it OK? Go to Step 8. Replace ABS wheel
speed sensor.
8 Refer to “Front / Rear Wheel Speed Sensor On-Vehicle Inspection” and/or “Rear Wheel Speed Sensor Removal and
Installation”, check output voltage or waveform.
Is specified voltage and/or waveform obtained? Substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck.
Replace sensor and
recheck.
