Suzuki Grand Vitara JB416 / JB420. Manual — part 208

4E-9 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” and
based on symptoms appearing on the vehicle (symptom obtained through Steps 1 and 2 and repair or replace faulty
parts, if any).

Step 6: Check for Intermittent Problem
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” 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

S5JB0A4504002

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”, “ABS Warning Lamp Comes ON Steady” or
“ABS Warning Lamp Flashes Continuously while
Ignition Switch Is ON”.

EBD Warning Lamp (Brake Warning Lamp)
Check

S5JB0A4504003

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”.

DTC Check

S5JB0A4504004

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 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

S5JB0A4504007

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 control module. Certain ABS
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 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 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.

ABS Warning Lamp Does Not Come ON at Ignition Switch ON

S5JB0A4504008

Wiring Diagram

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