DTC ClearanceS7RS0B4604006
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.

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 t ool. Refer to scan tool operator’s manual for further
derails.
4) After completing the clearance, tu rn ignition switch OFF and disconnec t scan tool from data link connector.
5) Perform “Driving Test” (Step 2 of “E lectronic Stability Program System Check” ) and “DTC Check” and confirm that
NO DTC is displayed on scan tool. )

Scan Tool DataS7RS0B4604024
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 comparis on 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 conditioning (if equipped).
• Set the wheel in straight-ahead position and hands off steering wheel.
• Turn OFF all electric loads (except ignition).
• Check that there is no DTC.
Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ESP ® control module. Certain
ESP ® control module functions will be modified if the
battery voltage falls below or rises above
programmed thresholds.

operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LR Wheel Speed (km/h, MPH): Wheel speed
is ESP ® control module internal parameter. It is
computed by reference puls es from the wheel speed
sensor. Brake Switch (ON, OFF):
This switch signal informs
the ESP ® control module whether the brake is active
or not.
Master Cyl Press (MPa): Brake fluid pressure from
brake master cylinder.
G Sensor (lateral) (G): Lateral acceleration is
measured by yaw rate / G sensor assembly and
output to ESP ® control module by pulse signal.

by yaw rate / G sensor assembly and output to
ESP® control module by pulse signal.
Steering angle Sen ( °): Steering wheel rotation angle
is measured by steering angle sensor and output to
ESP® control module by pulse signal.

ESP ® Warning Lamp Does Not Come ON at Ignition Switch ONS7RS0B4604008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ESP ® warning lamp is controlled by ESP ® control module through lamp driver module in
combination meter.
If ESP ® system is in good condition, ESP ® control module turns ESP ® warning lamp 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, ESP ® warning lamp is
turned ON continuously by ESP ® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP ® control module is disconnected.Inspection Item Referring section

Wiring Diagram4
Check ESP ® control module power supply circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP ® control module
connector at terminals “E85-1” and “E85-32”.
3) If OK, then turn ignition switch to ON position and measure voltage between each terminal of “E85-1”,
“E85-32” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5. “WHT/BLU” and/or
“WHT/RED” circuit
open.
5 Check ESP ® control module ground circuit
1) Turn ignition switch to OFF and measure resistance between each terminal of “E85-16”, “E85-47” and vehicle
body ground.
Is resistance less than 2
Ω? Go to Step 6.
Ground circuit for ESP®
control module open or
high resistance.
6 CAN communication circuit check
1) Check CAN communication circuit between combination
meter and ESP ® control module referring to “DTC
U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If warning
lamp remains ON,
substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.

Circuit Description
Operation (ON/OFF) of ABS warning lamp is controlled by ESP® control module through lamp driver module in
combination meter.
If antilock brake system is in good condition, ESP ® control module turns ABS warning lamp 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 lamp is
turned ON continuously by ESP ® control module. Also, it is turned ON continuously by lamp driver module when the
