ABS Control Module
Self-diagnosis function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time
and indicates the results (warning of abnormality occurrence and
DTC) through the “ABS” warning lamp as described below.
1) When ignition switch is turned ON, “ABS” warning lights for 2
seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in
good condition), “ABS” warning lamp turns OFF after 2 sec-
onds.
3) When an abnormality in the system is detected, “ABS” warn-
ing lamp lights and the area where that abnormality lies is
stored in the memory in ABS control module.
4) When Diag. switch terminal of monitor connector is
grounded, the abnormal area is output as DTC.
For procedure to clear all DTC’s, refer to the item “Diagnostic
Trouble Code (DTC) Clearance” in this section.
Fail-safe function
When an abnormality occurs (an abnormal DTC is detected),
ABS control module turns OFF the fail-safe transistor which sup-
plies power to ABS hydraulic unit. Thus, with ABS not operating,
brakes function just like the brake system of the vehicle without
ABS.SYSTEM CONDITIONDIAGNOSIS

“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.

Table – C “ABS” Warning Lamp Circuit Check – Lamp Flashes Continuously
While Ignition Switch is ON
CIRCUIT DESCRIPTION
When the diag. switch terminal is shorted or connected to the ground with the ignition switch ON, the diag. trou-
ble code (DTC) is indicated by flashing of the “ABS” warning lamp only in following cases.
Normal DTC (12) is indicated if no malfunction DTC is detected in the ABS.
A history malfunction DTC is indicated by flashing of the lamp if a current malfunction DTC is not detected at
that point although a history malfunction DTC is stored in memory.
