2) DRIVING TEST
Test drive the vehicle at 40 km/h for more than a minute and check if any trouble symptom (such as abnor-
mal lighting of “ABS” warning lamp) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not nec-
essary. Proceed to Step 3.
3) DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to “DTC Check” in this section.
4) DIAGNOSTIC TROUBLE CODE FLOW TABLE
According to Diagnostic Flow Table for the diagnostic trouble code confirmed in Step 3, locate the cause of
the trouble, namely in a sensor, switch, wire harness, connector, actuator, ABS control module or other part
and repair or replace faulty parts.
5)“DIAGNOSIS TABLE” IN SECTION 5
Check the parts or system suspected as a possible cause referring to “Diagnosis Table” in Section 5 and
based on symptoms appearing on the vehicle (symptoms obtained through Step 1)-a, 1)-b and 2) and repair
or replace faulty parts, if any.
6) CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
Intermittent Trouble in Section 0A and related circuit of trouble code recorded in Step 1)-c.
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 and perform test driving and confirm
that a normal code is indicated.

“ABS” Warning Lamp Check
Turn ignition switch ON and check that “ABS” warning lamp
comes ON for about 2 seconds and then goes OFF. If any faulty
condition is found, advance to Diagnostic Flow Table-A, B or C.
Diagnostic Trouble Code (DTC) Check
1) Test drive vehicle at 40 km/h for more than a minute.
2) Stop vehicle and while IG switch OFF, connect diagnosis
switch terminal (3) and ground terminal (2) of monitor con-
nector (1) with service wire (4).
3) Turn IG switch ON, read the flashing “ABS” warning lamp
which represents DTC as shown in example below and write
it down. When more than 2 DTC’s are stored in memory,
flashing for each DTC is repeated three times starting with
the smallest DTC number in increasing order.
For details of DTC, refer to “DTC Table”.
Example : When right front wheel speed sensor circuit opens (DTC 21)
4) After completing the check, turn ignition switch off, discon-
nect service wire from monitor connector.
NOTE:
“ABS” warning lamp indicates only following DTCs, DTC
12 which means that no malfunction DTC is stored and
history DTC which indicates history trouble area. When
there is current trouble, “ABS” warning lamp remains ON
and therefore DTC is not indicated.

DTC Check (Using SUZUKI Scan Tool)
1) Connect SUZUKI scan tool to data link connector after set-
ting cartridge for ABS to it.
Special tool
(A) : SUZUKI scan tool
2) Turn ignition switch ON.
3) 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.
4) After completing the check, turn ignition switch off and dis-
connect SUZUKI scan tool from DLC.
Diagnostic Trouble Code (DTC) Clearance
After repair or replace malfunction part(s), clear all DTC’s by pre-
forming the following procedure.
1) Turn ignition switch OFF.
2) Using service wire (4), connect diag. switch terminal (3) of
monitor connector (1) to ground terminal (2).
3) With connection described in above step 2) maintained, turn
ignition switch ON.
4) Repeat ON/OFF operation of service wire (4) at ground ter-
minal (2) at least 5 times within 10 seconds.
5) Turn ignition switch OFF and disconnect service wire (4)
from monitor connector (1).
6) Perform “DRIVING TEST” (Step 2 of “ABS Diagnostic Flow
Table”) and “DTC CHECK” and confirm that normal DTC
(DTC 12) is displayed.
WARNING:
When preforming a driving test, select a safe place where
there is neither any traffic nor any traffic accident possi-
bility and be very careful during testing to avoid occur-
rence of an accident.
NOTE:
Service wire ON time must be for 0.1 second and more.
NOTE:
It is also possible to clear DTC by using SUZUKI scan
tool. Refer to Cartridge Manual for procedure to clear
DTC.

Table – A “ABS” Warning Lamp Circuit Check – Lamp Does Not Come “ON” at
Ignition Switch ON
CIRCUIT DESCRIPTION
Operation (ON / OFF) of the “ABS” warning lamp is controlled by the ABS control module and ABS lamp driver
module.
If the Antilock brake system is in good condition, the ABS control module turns the “ABS” 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.
