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.

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.

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.

CRUISE CONTROL SYSTEM 8E-3
Cruise Control System
The cruise control system is a device which maintains a preset vehicle speed while driving at a high speed, e.g.,
on a highway. It allows the driver to drive his vehicle at a constant speed of 40 km/h (25 mile/h) or higher without
depressing the accelerator pedal (constant cruising). The system also has such functions as to change the vehi-
cle speed without operating the accelerator pedal (but using SET COAST and ACCEL RESUME switches), can-
cel cruise control (CANCEL switch) and resume the speed in memory automatically after cruise control is
cancelled (ACCEL RESUME switch). The system mainly consists of a vehicle speed sensor, an actuator
assembly incorporated with control module, cruise main switch, SET COAST switch, ACCEL RESUME switch
and CANCEL switch, etc.
