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.

DTC C1021, C1022 / C1025, C1026 / C1031, C1032 / C1035, C1036: Right-Front / Left-Front / Right-
Rear / Left-Rear Wheel Speed Sensor Circuit or Sensor Ring
S7RS0B4504012
Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the voltage at the terminal of each sensor while the ignition swit ch is ON. When the
voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal is inputted at
running, an applicable DTC will be set.
NOTE
When the vehicle was operated in any of the following ways, one of these DTCs may be set even when
the sensor is in good condition. If such possibility is suspected, clear DTC once referring to “DTC
Clearance” and then performing the driving test as described in Step 2 of “ABS Check”, check whether
or not any abnormality exists.
• The vehicle was driven with parking brake pulled.
• Wheel spin occurred while driving.
• Wheel(s) was turned while the vehicle was jacked up.
• The vehicle was stuck.

Refer to the following items for the details of each step.
Step 1: Malfunction Analysis
Customer complaint analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown in the following will facilitate collec ting information to the
point required for proper analysis and diagnosis. Step Action Yes No
1 ) Malfunction analysis
1) Perform “Customer complaint analysis: ”.
2) Perform “Problem symptom confirmation: ”.
3) Perform “DTC check, record and clearance: ” and recheck DTC.
Is there any malfunction DTC? Go to Step 4. Go to Step 2.
2 ) Driving test
1) Perform “Step 2: Driving Test: ”.
Is trouble symptom identified? Go to Step 3. Go to Step 6.
3 ) DTC check
1) Perform “DTC Check”.
Is it malfunction code? Go to Step 4. Go to Step 5.

Customer questionnaire (Example)
Problem symptom confirmation
If symptom in “Customer Questionnaire” is found or reproduced in the vehicle, confirm the symptom is problem or not.
(This step should be done with the customer if possible.) Check warning lamps related to brake system referring to
“EBD Warning Lamp (Brake Warning Lamp) Check”, “ABS Warning Lamp Check” and “ESP ® Warning lamp 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: ESP ® Check: ” to proceed the diagnosis.
When DTC which is recorded at DTC check procedure is not indicated anymore after performing DTC clearance,
ESP ® control module does not perform the system diagnosis, or temporary abnormality may occur, therefore go to
“Step 2: Driving Test: ” to proceed the diagnosis.

Downloaded from www.Manualslib.com manuals search engine 4F-14 Electronic Stability Program:
Step 2: Driving Test
Test the vehicle at 40 km/h for more than a minute including left and right turns and check if any trouble symptom
(such as ESP ® warning lamp and/or ABS warning lamp) exists.
If the malfunction DTC is confirmed at ignition switch ON, proceed to Step 3.
If the malfunction DTC is not confirmed at ignition switch ON, proceed to Step 6.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ESP ® Check
According to ESP ® 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 obtain ed through Steps 1 and 2 and repair or replace faulty
parts, if any).
Step 6: Intermittent Problem Check
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 ESP ® is free from any abnormal conditions. If what has been
repaired is related to the malfunction DTC, clear the DTC once referrin g to “DTC Clearance” and perform test driving
and confirm that no DTC is indicated.
ESP ® Warning lamp CheckS7RS0B4604022
1) Turn ignition switch ON.

Warning Lamp Does Not Come ON at Ignition Switch
ON” or “ESP ® Warning Lamp Comes ON Steady”.
ABS Warning Lamp CheckS7RS0B4604046
1) Turn ignition switch ON.
2) Check that ABS warning lamp (1) comes ON for
about 2 seconds and then goes off.
If any faulty condition is found, advance to “ABS
Warning Lamp Does Not Come ON at Ignition Switch
ON” or “ABS Warning Lamp Comes ON Steady”.
