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 “Electronic Stability Program 
Check”, and then clear the DTCs.

 

4) After completing the clearance, turn ignition switch OFF and disconnect scan tool from data link connector.
5) Perform “Driving Test” (Step 2 of “Electronic Stability Program Check”) and “DTC Check” and confirm that NO DTC 

is displayed on scan tool.

Scan Tool Data

S6JB0B4604024

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 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.

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 LR Wheel Speed (km/h, MPH):  Wheel speed 
is ESP

® control module internal parameter. It is 

computed by reference pulses from the wheel speed 
sensor.

Brake Switch (ON, OFF):  This switch signal informs 

the ESP

® control module whether the brake is active 

or not.

G Sensor (G):  Vehicle acceleration is measured by yaw 

rate / G sensor assembly and output to ESP

® 

control module by pulse signal for 4WD model.

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.

Yaw rate sensor (Deg/s):  Yaw rate sensor is measured 

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.

Stability control (ACTIVE, INACTIVE):  This indicates 

stability control in activation / deactivation.

TCS control (brake) (ACTIVE, INACTIVE):  This 

indicates brake function of TCS in activation / 
deactivation.

TCS control (engine) (ACTIVE, INACTIVE):  This 

indicates torque control of TCS in activation / 
deactivation.

ESP

® off state (cont) (ESP® ON, ESP® OFF):  State 

of ESP

® OFF switch.

Steering angle Sen (Neutral, NON neutral):  This 

indicates steering wheel angle measured by steering 
angle sensor is in straight-ahead or not.
