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 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.

Yaw rate / G sensor
The yaw rate / G sensor consists of the yaw rate (angular velocity in the vehicle turning direction) sensor and right-left
G (acceleration in right-left direction) sensor and is mounted to the P/S controller B/K at the lower part of the center
console. It detects the angular velocity in the vehicle turn ing direction and movement in the right-left direction, and
then it sends that information to ESP ® control module.
Wheel speed sensor
The vehicle speed is detected by the hall IC type wheel speed sensor (1) and encoder (4). The wheel speed sensor is
fixed to the knuckle and includes a hall IC (3) having 2 hall elements (2).
The encoder consisting of a permanent ma gnet which has S/N electrodes turns inside of the wheel hub along with the
wheel. The wheel speed sensor outputs alternate current.
As the cycle of the alternate current is in proportion to the revolution speed of the encoder, this AC signal (5) is
converted into the voltage signal in the ESP ® control module (6) for detection of the wheel speed.
ESP ® Hydraulic Unit / Control Module
Assembly Description
S7RS0B4601002
ESP ® control module is a component of ESP ® hydraulic
unit / control module assembly and has the following
functions.
Self-Diagnosis Function
ESP ® control module monitors each input and output
signals. When ESP ® control module detects any
malfunction, some of ABS warning lamp (1), EBD
warning lamp (brake warning lamp) (2), ESP ® warning
lamp (3), SLIP indicator lamp (4), ESP ® OFF lamp (5)
are turned ON and indicate the abnormality to driver.
• When ignition switch is turned ON, ABS warning lamp, EBD warning lamp, ESP ® warning lamp, SLIP
indicator lamp and ESP ® OFF lamp light for 2
seconds to check its circuit.
• When no abnormality is detected (the system is in good condition), ABS warning lamp, EBD warning
lamp, ESP ® warning lamp, SLIP indicator lamp and
ESP ® OFF lamp turn OFF after 2 seconds.
• When an abnormality in the system is detected, some of ABS warning lamp, EBD warning lamp (brake
warning lamp), ESP ® warning lamp, SLIP indicator
lamp and/or ESP ® OFF lamp are turned ON and the
area where that abnormality lies is stored in the
memory in ESP ® control module. Fail-Safe Mode
When ESP
® control module detects abnormality, the
system goes into fail-safe mode. And some of functions
of ABS, TCS, stability control system are shut down. For
details of fail safe mode, re fer to “Fail-Safe Table”.

ESP ® warning lamp If ESP ® systems has abnormality, the lamp turns “ON”.
SLIP indicator lamp • If stability cont rol system and traction control system is active, the lamp blinks
at 5 Hz.
• If Steering angle sensor calibration is incompleted, the lamp blinks at 1 Hz.
ESP ® OFF lamp • If ESP ® OFF switch is turned “ON”, the ESP ® OFF lamp light up. When it is
“ON”, TCS and stability control system functions are controlled not to work.
• ESP® OFF lamp light up to indicate th at brake control of traction control
function is controlled not to act if brake pad temperature is over 320 °C (608 °F)
