Precautions
Precautions in Diagnosing TroublesS6RW0D4500001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS 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 vehicle 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” and “Precaution for CAN
Communication System in Section 00” 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 control module during inspection.)• When disconnecting ABS hydraulic unit / control
module connector (1), pull up lock lever (2) of
connector.
When connecting, set the connector on ABS hydraulic
unit / control module assembly and pull down the lock
lever (2) until it locks.
• Communication of ECM, BCM, combination meter,
4WD control module (if equipped), keyless start
control module (if equipped), TCM (if equipped), data
link connector and ABS control module is established
by CAN (Control 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 ServiceS6RW0D4500002

Problem symptom confirmation
Check if what the customer claimed in “Customer
Questionnaire” is actually found in the vehicle and if that
symptom is found, whether it is identified as a failure.
(This step should be shared with the customer if
possible.) Check warning lights related to brake system
referring to “EBD Warning Light (Brake Warning Light)
Check” and “ABS Warning Light Check”.
DTC check, record and clearance
Perform “DTC Check” procedure, record it and then
clear it referring to “DTC Clearance”.
Recheck DTC referring to “DTC Check”.
When DTC which is recorded at DTC check procedure is
detected again after performing DTC clearance, go to
“Step 4: ABS Check: ” to proceed the diagnosis.
When DTC which is recorded at DTC check procedure is
not indicated anymore after performing DTC clearance,
ABS control module does not perform the system
diagnosis, or temporary abnormality may occur,
therefore go to “Step 2: Driving Test: ” to proceed the
diagnosis.
Step 2: Driving Test
Test drive the vehicle at 40 km/h (25 MPH) for more than
a minute and check if any trouble symptom (such as
abnormal lighting of ABS warning light) exists.
If the malfunction DTC is confirmed again at ignition
switch ON, driving test as described is not necessary.
Proceed to Step 3.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ABS Check
According to ABS Check for the DTC confirmation in
Step 3, locate the cause of the trouble, namely in a
sensor, switch, wire harness, connector, actuator
assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible
cause referring to “Brakes Symptom Diagnosis in
Section 4A” and based on symptoms appearing on the
vehicle (symptom obtained through Steps 1 and 2 and
repair or replace faulty parts, if any).
Step 6: Check for Intermittent Problem
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of trouble code recorded in Step 1
to 3.
Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the
ABS is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once referring to “DTC Clearance” and perform
test driving and confirm that no DTC is indicated.ABS Warning Light CheckS6RW0D4504002
