4E-12 ABS:

DTC Clearance

S6JB0A4504006

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 clearance, turn ignition switch

OFF and disconnect scan tool from data link
connector.

5) Perform “Driving Test” (Step 2 of “ABS Check”) and

“DTC Check” and confirm that NO DTC is displayed
on scan tool.

Scan Tool Data

S6JB0A4504007

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. (Normal braking operation)

Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input

signal read by the ABS (ESP

®) control module.

Certain ABS (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 LF Wheel Speed (km/h, MPH): Wheel speed
is an ABS (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 ABS (ESP

®) control module whether the brake

is active or not.

G Sensor (G): The G-Sensor converts gravity during

the vehicle acceleration / deceleration in to a voltage
conditions and controls the ABS for 4WD model.
(non-ESP

® model)

Vehicle acceleration is measured by yaw rate / G
sensor assembly and output to ESP

® control

module by pulse signal for 4WD model. (ESP

®

model)

ABS Warning Light Does Not Come ON at Ignition Switch ON

S6JB0A4504008

Wiring Diagram

Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS (ESP

®) control module through light driver module in

combination meter.
If the antilock brake system is in good condition, ABS (ESP

®) control module turns ABS warning light 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 light is turned ON continuously by ABS (ESP

®) control module. Also, it is turned ON continuously by light

driver module when the connector of ABS (ESP

®) control module is disconnected.

ABS Warning Light Comes ON Steady

S6JB0A4504009

Wiring Diagram
Refer to “ABS Warning Light Does Not Come ON at Ignition Switch ON”.

Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS (ESP

®) control module through light driver module in

combination meter.
If the Antilock brake system is in good condition, ABS (ESP

®) control module turns ABS warning light 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 light is turned ON continuously by ABS (ESP

®) control module. Also, it is turned ON continuously by light

driver module when the connector of ABS (ESP

®) control module is disconnected.

2) Check for proper connection to ABS (ESP

®) control

module connector at terminals “E03-1” and “E03-14” (or
“E53-1” and “E53-32”).

3) If OK then turn ignition switch to ON position and

measure voltage between each terminal of “E03-1”,
“E03-14” (or “E53-1”, “E53-32”) and vehicle body
ground.

Are they 10 – 14 V?

Go to Step 5.
