Suzuki Grand Vitara JB419. Service manual — part 96

Electronic Stability Program: 4F-17

DTC Clearance

S5JB0B4604052

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 lamp 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

S5JB0B4604054

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 front wheels 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 vehicle.

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.
