4E-10 ABS: 

Step 2: Driving Test
Test drive the vehicle at 40 km/h for more than a minute and check if any trouble symptom (such as abnormal lighting 
of ABS warning light) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described is not necessary. Proceed to 
Step 3.

Step 3: DTC Check
Recheck DTC referring to “DTC Check”.

Step 4: ABS Check
According to ABS Check for the DTC confirmation in Step 3, locate the cause of the trouble, namely in a sensor, 
switch, wire harness, connector, actuator assembly or other part and repair or replace faulty parts.

Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible cause referring to “Brakes Symptom Diagnosis in Section 4A” an
based on symptoms appearing on the vehicle (symptom obtained through Steps 1 and 2 and repair or replace faulty 
parts, if any).

Step 6: Intermittent Problem Check
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to 
“Intermittent and Poor Connection Inspection in Section 00 in related manual” and related circuit of trouble code 
recorded in Step 1 to 3.

Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the ABS is free from any abnormal conditions. If what has been 
repaired is related to the malfunction DTC, clear the DTC once referring to “DTC Clearance” and perform test driving 
and confirm that no DTC is indicated.

ABS Warning Lamp Check

S5JB0E4504002

1) Turn ignition switch ON.
2) Check that ABS warning lamp (1) comes ON for 

about 2 seconds and then goes off.
If any faulty condition is found, advance to “ABS 
Warning Lamp Does Not Come ON at Ignition Switch 
ON” 
or “ABS Warning Lamp Comes ON Steady”.

EBD Warning Lamp (Brake Warning Lamp) 
Check 

S5JB0E4504003

NOTE
Perform this check on a level place.

 

1) Turn ignition switch ON with parking brake applied.
2) Check that EBD warning lamp (brake warning lamp) 

(1) is turned ON.

3) Release parking brake with ignition switch ON and 

check that EBD warning lamp (brake warning lamp) 
goes off.
If it doesn’t go off, go to “EBD Warning Lamp (Brake 
Warning Lamp) Comes ON Steady”.

1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector 

(1).

Special tool
(A):  SUZUKI scan tool

3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on 

SUZUKI scan tool and print it or write it down. Refer 
to SUZUKI scan tool operator’s manual for further 
details.

NOTE
If SUZUKI scan tool can not communicate 
ABS (ESP

®) hydraulic unit / control module, 

perform “Serial Data Link Circuit Check”.

 

5) After completing the check, turn ignition switch off 

and disconnect SUZUKI scan tool from DLC.

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 “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

S5JB0E4504007

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 vehicle. 
(without ESP

®)

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

® control 

module by pulse signal for 4WD vehicle. (with 
ESP

®)

ABS Warning Lamp Does Not Come ON at Ignition Switch ON

S5JB0E4504008

Wiring Diagram

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

®) control module through lamp driver module in 

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

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

driver module when the connector of ABS (ESP

®) control module is disconnected.
