NOTE:
Perform this check on a level place.
1) Turn ignition switch ON with parking brake applied.
2) Check that brake warning lamp 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 ªTABLE-Eº in this section.
ªABSº WARNING LAMP CHECK
1) Turn ON the ignition switch.
2) Check that ªABSº warning lamp lights for about 2 seconds and
then goes OFF.
If anything faulty is found, advance to Diagnostic table ± A, B or
C.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(USING ªABSº WARNING LAMP)
1) Using service wire, connect diag. switch terminal of diagnosis
connector to ground.
2) Turn ignition switch ON.
3) Read flashing of ªABSº warning lamp which represents DTC as
shown in example below and write it down. When more than 2
DTC's are stored in memory, deflection and flashing for each
DTC is repeated three times starting with the smallest DTC num-
ber in increasing order.
For details of DTC, refer to ªDTC Tableº.

TABLE ± A ªABSº WARNING LAMP CIRCUIT CHECK ± LAMP DOES NOT
COME ªONº AT IGNITION SWITCH ON
CIRCUIT DESCRIPTION
Operation (ON / OFF) of the ªABSº warning lamp is controlled by the ABS control module and ABS lamp driver mod-
ule.
If the Antilock brake system is in good condition, the ABS control module turns the ªABSº warning lamp ON at the
ignition switch ON, keeps it ON for 2 seconds only and then turns it OFF. If an abnormality in the system is detected,
the lamp is turned ON by ABS control module. Also, it is turned ON by ABS lamp driver module when the connector
of the ABS control module was disconnected.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

BRAKE INTERLOCK SYSTEM
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and inter-
lock cable control system.
The shift lock solenoid control system is so designed that the selec-
tor lever can not be shifted from ªPº range position unless the igni-
tion switch is turned ON and the brake pedal is depressed. And the
interlock cable control system is so designed that the selector lever
cannot be shifted from ªPº range position unless the ignition switch
is turned to ªACCº or ªONº position. Also, the ignition key cannot be
pulled out of the key slot unless the selector lever is in ªPº range.
SHIFT LOCK SOLENOID CONTROL OPERATIONS
When the select lever is in ªPº range, the ignition key position is
ªONº and depressing the brake pedal cause the electric current to
flow to the solenoid. As the shift lock solenoid rod (or the lock plate)
is drawn toward the solenoid in this state, it frees the interlock cam
(or the detent pin), which then allows the select lever to be shifted
from ªPº range to any other position.
Even when the select lever is in ªPº range, if the ignition key position
is ªLOCKº or ªACCº or the brake pedal is not depressed, the electric
current does not flow to the solenoid.
In this state, the shift lock solenoid rod (or the lock plate) is pushed
away from the solenoid by spring force and it obstructs the interlock
cam (or the detent pin) movement. Thus the select lever button
does not work even when pressed and the select lever shift is pre-
vented.
