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.

S7RS0B4506005
Output Voltage Inspection
1) Disconnect negative cable from battery.
2) Hoist vehicle a little.
3) Disconnect wheel speed sensor connector.
4) Disconnect wheel speed grommet from vehicle body.
5) Set up measuring devices as shown in figure, the resistance to 115 Ω and the power supply voltage to
12 V.
CAUTION!
Incorrect voltage and/or wrong connection
cause damage to wheel speed sensor.

6) Measure voltage at resistance without wheel rotation.
If voltage is out of specification, check sensor,
mating encoder and their installation conditions.
Voltage at the resistance (115
Ω) without wheel
rotation

7) Measure voltage at resistance with wheel rotation and confirm voltage alternately changes between
high and low voltages.
If voltage does not change with wheel rotation, check
sensor, mating encoder and their installation
conditions.

Precautions in Speedometer Test or Other TestsS7RS0B4600005
When performing speedometer or other tests using speedometer tester or chassis dynamometer, ESP® function must
be deactivated by ESP ® OFF switch or using SUZUKI scan to ol to complete the tests correctly.
When using SUZUKI scan tool, set to the “MISC. TEST” mode to stop the ESP ® function. Refer to SUZUKI scan tool
operator's manual for further details.
General Description
Electronic Stability Program DescriptionS7RS0B4601006
Electronic Stability Program (ESP ®) is an auxiliary function to enable the vehicle to av oid a danger safely while the
vehicle is running, stopping or turning.
Electronic Stability Program (ESP ®) consists of following functions.
ESP ® is a registered trademark of Daimler Chrysler AG.
Antilock Brake System (ABS)
This system prevents tire locking which may occur when br ake is applied suddenly or on slippery roads. With this
function, as the vehicle body is kept in the stable state an d tires unlocked, the driver can avoid any obstacle by turning
the steering wheel.
Electronic Brake force Distribution (EBD)
This function distributes braking force of front and rear wheels properly according to the vehicle load condition.
With this function, the braking force of the front and rear wheels is controlled for the optimum effect to secure the
maximum braking force regardless of the loadage.
Traction Control System (TCS)
This system controls the engine and brake to prevent the dr iving wheels from spinning at the time of starting and
accelerating. Particularly, this fu nction is helpful for safe driving on muddy or icy roads. When ESP ® control module
detects wheel spinning using information from the yaw rate sensor and wheel speed sensor, it lower the engine torque
by closing the electronic controlled thro ttle and controlling ignition. At the same time, brake is applied to the spinning
tire.
Stability Control
This function controls the vehicle body in the stable state by controlling the engine and braking so as to prevent the
vehicle from over-steering or under-steering while turning.
When under-steering occurs, this function lowers the engine torque and applies brake to the inner rear wheel in the
vehicle forward direction so as to pr event the vehicle from moving outward.
When over-steering occurs, this function applies brake to the outer front wheel in the vehicle forward direction so as to
prevent the vehicle from moving inward. Sensor Procedures required calibration
Steering angle sensor • Power is not su pplied to steering angle sensor. (battery, fuse and/or connector is
removed.)
• Steering angle sensor is replaced.
• Power is not supplied to ESP ® control module. (battery, fuse and/or connector is
removed.)
• ESP® hydraulic unit / control module assembly is replaced.
Master cylinder pressure sensor • ESP® hydraulic unit / control module assembly is removed or replaced.
Yaw rate / G sensor assembly • Yaw rate / G sensor assembly is removed or replaced.
• ESP® hydraulic unit / control module assembly is replaced.
