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” proced ure, 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 performi ng 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 for more than a minute
and check if any trouble symptom (such as abnormal
lighting of ABS warn ing light) exists.
If the malfunction DTC is co nfirmed 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, con nector, 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 CheckS7RS0B4504002
1) Turn ignition switch ON.
2) Check that ABS warning light (1) comes ON for
about 2 seconds and then goes off.
If any faulty condition is found, advance to “ABS
Warning Light Does Not Come ON at Ignition Switch
ON” or “ABS Warning Light Comes ON Steady”.
EBD Warning Light (Brake Warning Light)
Check
S7RS0B4504003
NOTE
Perform this check on a level place.

1) Turn ignition switch ON with parking brake applied.
2) Check that EBD warning lig ht (brake warning light)
(1) is turned ON.
3) Release parking brake with ignition switch ON and check that EBD warning lig ht (brake warning light)
goes off.
If it doesn’t go off, go to “EBD Warning Light (Brake
Warning Light) Comes ON Steady”.

1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (1).
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
NOTE
If SUZUKI scan tool can not communicate
ABS hydraulic unit / control module, perform
“Serial Data Link Circuit Check”.

5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from DLC.

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.
