1-2. PROBLEM SYMPTOM CONFIRMATION
Check if what the customer claimed in CUSTOMER QUESTIONNAIRE is actually found in the vehicle and
if that symptom is found, whether it is identified as a failure. (This step should be shared with the customer
if possible.) When ªABSº warning lamp is not operated correctly, proceed to ªDiagnostic Flow Table-A, B or
Cº.
1-3. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEARANCE
Perform ªDiagnostic Trouble Code Checkº as shown below, record it and then clear it referring to ªDiagnostic
Trouble Code Clearanceº in this section.
If the malfunction DTC which was once displayed and then cleared cannot be detected (indicated) again when
the ignition switch is turned ON, attempt to diagnose the trouble based on the DTC recorded in this step may
mislead the diagnosis or make diagnosing difficult. Proceed to Step 2 to check ABS control module for proper
self-diagnosis function.
If the malfunction DTC which was once displayed and then cleared can be detected (indicated) again when
ignition switch is turned ON, proceed to Step 3.
2. DRIVING TEST
Test drive the vehicle at 40 km / h for more than a minute and check if any trouble symptom (such as abnormal
lighting of ªABSº warning lamp) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not neces-
sary. Proceed to Step 3.
3. DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to item ªDTC CHECKº as shown below.
4. DIAGNOSTIC TROUBLE CODE FLOW CHART
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. ªDIAGNOSISº IN ªBRAKEº SECTION
Check the parts or system suspected as a possible cause referring to ªDiagnosisº in ªBRAKESº section and
based on symptoms appearing on the vehicle (symptoms obtained through Steps 1-1, 1-2 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 IN-
TERMITTENT TROUBLE in ªGENERAL INFORMATIONº section and related circuit of trouble code recorded
in Step 1-3.
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 nor-
mal code is indicated.

nect SUZUKI scan tool from DLC.
DIAGNOSTIC TROUBLE CODE (DTC)
CLEARANCE
WARNING:
When performing a driving test, select a safe place where
there is neither any traffic nor any traffic accident possibil-
ity and be very careful during testing to avoid occurrence of
an accident.
After repair or replace malfunction part(s), clear all DTC's by per-
forming the following procedure.
1) Turn ignition switch OFF.
2) Using service wire, connect diag. switch terminal of diag. con-
nector to diag. ground terminal.
3) With connection described in above step 2) maintained, turn
ignition switch ON.
4) Repeat on / off operation of service wire at diag. ground terminal
at least 5 times within 10 seconds.
NOTE:
Service wire ON time must be for 0.1 second and more.
5) Turn ignition switch OFF and disconnect service wire from diag.
connector.
6) Perform DRIVING TEST and DTC CHECK and confirm that nor-
mal DTC (DTC 12) is displayed; not malfunction DTC.
NOTE:
It is also possible to clear DTC by using SUZUKI scan tool.
Refer to Cartridge Manual for procedure to clear DTC.

2Check Transmission Range Switch (Sensor) Circuit for
Operation.
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition
switch OFF.
2) Turn ignition switch ON and check transmission
range signal (P, R, N, D, 2 or L) on display
when shifting select lever to each range.
Is applicable range indicated?
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals C51-1-15, C51-1-16,
C51-1-17, C51-1-18, C51-1-27 and C51-1-28 for
G16/J20 (C51-1-4, C51-1-3, C51-1-13, C51-1-12,
C51-1-20 and C51-1-19 for H25) respectively with
select lever shifted to each range.
Taking terminal C51-1-28 for G16/J20 (C51-1-20 for
H25) as an example, is battery voltage indicated
only when select lever is shifted to ª2º range and
0 V for other ranges as shown in figure?
Check voltage at other terminals likewise, referring
to figure.

24WD low switch and its circuit check:
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition
switch OFF.
2) Turn ignition switch ON.
3) Select ªData listº mode on scan tool.
4) Check 4WD low switch signal (ON or OFF) on
display when shifting transfer lever to each
position.
4H or 2H position : OFF
4L position : ON
Is OFF / ON displayed as described above?
When not using SUZUKI scan tool:
1) Remove PCM cover.
2) Turn ignition switch ON.
3) Check voltage at terminal C51-1-26 for G16 / J20
(C51-1-5 for H25) of PCM connector connected
when shifting transfer lever to each position.
4H or 2H position : 10 ± 14 V
4L position : 0 ± 1 V
Is voltage as specified?Check for poor con-
nection at the termi-
nal of PCM if voltme-
ter is used in Step 2.
If connection is OK,
intermittent trouble
or faulty PCM.
Check for intermittent
referring to ªIntermit-
tent and Poor

Section 0A.Go to Step 3.
34WD low switch check:
1) Check 4WD low switch for operation referring to
ª4WD Low Switch Inspectionº below.
Is check result satisfactory?ªOr / Wº or ªBº circuit
open or short. If wires
and connections are
OK, substitute a
known-good PCM
and recheck.Replace 4WD low
switch.
4WD Low Switch Inspection
1) Disconnect negative cable at battery.
2) Disconnect 4WD low switch coupler.
3) Check continuity between 4WD low switch terminals.
There should be continuity when transfer lever shifted to 4L posi-
tion and should be infinity when transfer lever shifted to 4H or 2H
positions.
If not, replace 4WD low switch.
4) Connect 4WD low switch coupler and battery negative cable.

NOTE:
When reading DTC stored in ECM / PCM using Suzuki scan
tool, select ªECMº from the applications menu and ªSU-
ZUKI modeº from the communication mode menu dis-
played on Suzuki scan tool.
If ECM / PCM detects a trouble in both electric fuel injec-
tion system and immobilizer control system, Suzuki scan
tool indicates trouble codes of both systems using Suzu-
ki mode of ECM application.
If communication between Suzuki scan tool and ECM / PCM is
not possible, check if Suzuki scan tool is communicable by con-
necting it to ECM / PCM in another vehicle. If communication is
possible in this case, Suzuki scan tool is in good condition. Then
check data link connector and serial data line (circuit) in the ve-
hicle with which communication was not possible.
5) After completing the check, turn ignition switch OFF and discon-
nect Suzuki scan tool from data link connector (DLC).

as to whether it is a current one or a history one. (But use of scan tool (Tech 1) will make identification
possible.)
