Diagnosis
To ensure that the trouble diagnosis is done accurately and
smoothly, observe “PRECAUTIONS IN DIAGNOSING TROU-
BLES” and follow “ABS DIAGNOSTIC FLOW TABLE”.
Precautions in Diagnosing Troubles
If the vehicles was operated in any of the following ways,
ABS warning lamp may light momentarily but this does not
indicate anything abnormal in ABS.
–The vehicle was driven with parking brake pulled.
–The vehicle was driven with brake dragging.
–The vehicle was stuck in mud, sand, etc.
–Wheel spin occurred while driving.
–Wheel(s) was rotated while the vehicle was jacked up.
Be sure to read “PRECAUTIONS FOR ELECTRONIC CIR-
CUIT SERVICE” in Section 0A before inspection and
observe what is written there.
Be sure to use the trouble diagnosis procedure as described
in the flow table. Failure to follow the flow table may result in
incorrect diagnosis. (Some other diagnosis trouble code may
be stored by mistake in the memory of ABS control module
during inspection.)
When disconnecting ABS hydraulic unit/control module con-
nector (1), pull up lock (2) of connector.
When connecting, set the connector on ABS hydraulic unit/
control module assembly and push the lock (2) down.

ABS Warning Lamp Check
1) Turn ignition switch ON.
2) Check that ABS warning lamp (1) comes ON for about 2 sec-
onds and then goes off.
If any faulty condition is found, advance to Diagnostic Flow
Table-A, B, C or D.
EBD Warning Lamp (Brake Warning Lamp)
Check
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 “TABLE-E” in this section.
NOTE:
Perform this check on a level place.

ANTILOCK BRAKE SYSTEM (ABS) 5E2-15
Table-A ABS Warning Lamp Circuit Check – Lamp Does Not Come “ON” at
Ignition Switch ON
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.
INSPECTION
1. Main fuse 5. ABS warning lamp 9. Brake fluid level switch
2. Ignition switch 6. Brake warning lamp 10. ABS hydraulic unit/control module assembly
3. Circuit fuse 7. Lamp driver module 11. ABS hydraulic unit/control module connector
4. Combination meter 8. Parking brake switch
Step Action Yes No
1 1) Turn ignition switch ON.
Do other warning lamp come ON?Go to Step 2. Go to Step 4.
2 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
Does ABS warning lamp light with ignition
switch ON?Substitute a known-good ABS
hydraulic unit/control module
assembly and recheck.Go to Step 3.
3 1) Remove combination meter.
Is bulb of ABS warning lamp in good condition?“BLU/ORN” circuit shorted to
ground. If OK, replace combina-
tion meter (lamp driver module).Replace bulb.
4 Is IG fuse in good condition? Open in “BLK/WHT” wire to
combination meter or poor con-
nection.Repair and replace.

Table-E EBD Warning Lamp (Brake Warning Lamp) Check – Lamp Comes
“ON” Steady
CIRCUIT DESCRIPTION
EBD warning lamp (brake warning lamp) is controlled by parking brake switch, brake fluid level switch and ABS
control module/hydraulic unit assembly through lamp driver module in combination meter. Refer to “TABLE – A”
for circuit diagram.
INSPECTION
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 replen-
ish brake fluid.
2Does “ABS” warning lamp come on? Perform “TABLE – B” pre-
viously outlined.Go to Step 3.
3 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
2) Check for proper connection to ABS
hydraulic unit/control module connector at
terminals “E136-10”.
3) If OK, apply chocks to wheels and select
gear in neutral position (P range for A/T).
4) Keep brake pedal depressed and start
engine.
Release parking brake.
5) Connect terminal “E136-10” of discon-
nected connector to ground using service
wire.
Does EBD warning lamp (brake warning lamp)
turn off?Substitute a known-good
ABS hydraulic unit/con-
trol module assembly and
recheck.“BRN” circuit open.
If wire and connection are
OK, replace combination
meter.

Circuit or Sensor Ring
DESCRIPTION
The ABS control module monitors the voltage at the terminal of each sensor while the ignition switch is ON.
When the voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal is
inputted at starting or while running, an applicable DTC will be set.

2. ABS control module/hydraulic unit assembly 5. Left-rear wheel speed sensor
3. Left-front wheel speed sensor 6. Right-rear wheel speed sensor
NOTE:
When the vehicle was operated in any of the following ways, one of these DTCs may be set even when
the sensor is in good condition. If such possibility is suspected, repair the trouble (dragging of brake,
etc.) of the vehicle, clear DTC once and then after performing the driving test as described in Step 2 of
“ABS DIAGNOSIS FLOW TABLE”, check whether or not any abnormality exists.
The vehicle was driven with parking brake pulled.
The vehicle was driven with brake dragging.

On-Vehicle Service
Precautions
When connector are connected to ABS hydraulic unit/control
module assembly, do not disconnect connectors of sensors and
turn ignition switch ON. Then DTC will be set in ABS control mod-
ule.
ABS Hydraulic Unit Operation Check (Using
SUZUKI Scan Tool)
1) Connect SUZUKI scan tool to data link connector (DLC) (1)
with ignition switch OFF.
Special tool
(A) : SUZUKI scan tool
2) Turn ignition switch to ON position and check actuator opera-
tion using “HYDRAULIC CONTROL TEST” under “miscella-
neous test” (“MISC. TEST”) mode of SUZUKI scan tool.
ABS Hydraulic Unit Operation Check
(Not Using Suzuki Scan Tool)
1) Check that basic brake system other than ABS is in good
condition.
2) Check that battery voltage is 11V or higher.
3) With “ABS” warning lamp, check that no abnormality is
detected in ABS. Refer to “DIAGNOSTIC TROUBLE CODE
(DTC) CHECK” in this section.
4) Lift up vehicle.
5) Set transmission to neutral and release parking brake.
6) Turn each wheel gradually by hand to check if brake drag-
ging occurs. If it does, correct.
7) With diag. switch terminal (2) of diagnosis connector (1) con-
nected to ground by using service wire (4), turn ignition
switch to ON position and check that “ABS” warning lamp
indicates normal DTC (DTC 12) referring to “DIAGNOSTIC
TROUBLE CODE (DTC) TABLE” in this section.
8) Turn ignition switch to OFF position.
