Suzuki Grand Vitara JB416 / JB420 / JB419. Manual — part 281

4E-16 ABS:

EBD Warning Light (Brake Warning Light) Comes ON Steady

S6JB0A4504010

Wiring Diagram

Circuit Description
EBD warning light (brake warning light) is controlled by parking brake switch, brake fluid level switch and ABS (ESP

®)

control module assembly through light driver module in combination meter.
EBD warning light turns ON when parking brake switch is ON and/or brake fluid level is lower than minimum level.
The information of parking brake switch and brake fluid level are transmitted from BCM to light driver module in
combination meter through CAN communication line.

Troubleshooting

Serial Data Link Circuit Check

S6JB0A4504011

Step

Action

Yes

No

1

1) Make sure that:

• Parking brake is completely released.
• Brake fluid level is upper than the minimum level.

Are the check results OK?

Go to Step 2.

Release parking brake
completely and/or
replenish brake fluid.

2

1) Turn ignition switch to ON position.

Does “ABS” warning light come on steady?

Perform “ABS Warning
Light Comes ON
Steady” previously
outlined.

Go to Step 3.

3

1) CAN communication circuit between combination meter,

ABS (ESP

®) control module and BCM referring to “DTC

U1073: Control Module Communication Bus Off (Petrol
Engine Model)”.

Is CAN communication circuit in good condition?

Substitute a known-
good combination meter
and recheck. If ABS
warning light remains
ON, substitute a known-
good ABS (ESP

®)

hydraulic unit / control
module assembly and
recheck.

Repair or replace.

Inspection

Step

Action

Yes

No

1

1) Turn ignition switch to ON position.

Does ABS warning light come ON?

Go to Step 2.

Go to Step 6.

2

1) Turn ignition switch to OFF position.

Are main fuses for ABS pump motor and ABS solenoid in
good condition?

Go to Step 3.

Replace fuse and check
for short.

3

1) Disconnect ABS hydraulic unit / control module

connector.

2) Check for proper connection to ABS hydraulic unit /

control module connector at terminal “E03-7”.

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

measure voltage between terminal “E03-7” and vehicle
body ground.

Is it 10 – 14 V?

Go to Step 4.

“GRN/ORN” wire circuit
open.

4

1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS hydraulic unit /

control module connector at terminals “E03-1” and “E03-
14”.

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

measure voltage between each terminal of “E03-1”,
“E03-14” and vehicle body ground.

Are they 10 – 14 V?

Go to Step 5.

“WHT/RED” and/or
“WHT/BLU” wire circuit
open.

5

1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS hydraulic unit /

control module connector at terminals “E03-13” and
“E03-26”.

3) If OK, measure resistance between each terminal of

“E03-13”, “E03-26” and vehicle body ground.

Are resistance less than 2

Ω

?

Go to Step 6.

Ground circuit for ABS
hydraulic unit / control
module open or high
resistance.

6

1) Check if communication is possible by trying

communication with other controller (ECM, TCM, BCM,
4WD control module or SDM).

Is it possible to communicate with other controller?

Go to Step 7.

Repair open in common
section of serial data
circuit (“PPL/WHT” wire
circuit) used by all
controllers or short to
ground or power circuit
which has occurred
somewhere in serial
data circuit (“PPL/WHT”
wire circuit).

7

1) Turn ignition switch to ON position.
2) Measure voltage between terminal B of data link

connector and vehicle body ground.

Is voltage 10 – 12 V?

Go to step 8.

Terminal B circuit open
or shorted to ground.

8

1) Turn ignition switch to OFF position.
2) Measure resistance between the following terminals;

• Terminal G of data link connector and vehicle body

ground.

• Terminal G1 of data link connector and vehicle body

ground.

Is each resistance 1

Ω

or less?

Go to step 9.

Terminal G and/or G1
circuit open or high
resistance.

DTC C1015: G Sensor Circuit Failure (4WD Model)

S6JB0A4504012

For vehicle equipped with ESP

®, go to “DTC C1015 / C1017 / C1023: Longitudinal G Sensor / Lateral G Sensor / Yaw

Rate Sensor in Yaw Rate / G Sensor Assembly Failure in Section 4F”.

Description
If the signal voltage of G sensor while at a stop does not vary from that while running, this DTC is set. (for 4WD
vehicle)
Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the DTC and
check again.

DTC Troubleshooting

1) Ignition switch OFF.
2) Check for proper connection from harness to control module.
3) If OK, substitute an ABS hydraulic unit/control module assembly with correct part number.
4) Recheck system.

9

1) Turn ignition switch to OFF position.
2) Check proper connection at “E03-5” (“PPL/WHT” wire)

terminal for serial data circuit.

3) If OK, then check resistance between “E03-5” (“PPL/

WHT” wire) terminal and “PPL/WHT” wire terminal (2) for
serial data circuit in DLC (1).

Is resistance 1

Ω

or less?

Substitute a known-
good ABS hydraulic unit
/ control module and
recheck.

Repair high resistance
or open in “PPL/WHT”
wire circuit for anti lock
brake system.
