Using SUZUKI Scan Tool1) Prepare SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to data link connector (DLC) located on underside of
instrument panel of driver’s side.
Special tool
(A): SUZUKI scan tool 3) Turn ignition switch ON.
4) 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.
If communication between SUZUKI scan tool and
BCM is not possible, check if SUZUKI scan tool is
communicable by connecting it to BCM 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
vehicle with which communica tion was not possible.
5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from data link
connector.

Without Using SUZUKI Scan Tool1) Turn ignition switch to OFF position.
2) Perform following Steps a) to d) within 10 seconds af ter ignition switch is turned ON and engine stops.
a) Turn headlight switch to “SMALL” position.
b) Turn headlight switch to “OFF” position.
c) Repeat Steps a) and b) 2 times.
d) Press and release driver side door switch 3 times.
3) Check DTC displayed on odometer of combination meter or read flashing pattern of theft deterrent light which
represents DTC as shown in the following example and write it down.
When more than 2 DTCs are stored in memory, flashing for each DTC starts with the smallest DTC number in
increasing order. Also, DTC is indicated repeatedly until the ignition switch is turned OFF.
4) After completing the check, turn ignition switch to OFF position.
DTC ClearanceS7RS0BA204006
After repair or replace of malfunction part(s), clear all
DTCs by performing the following procedure.
Using SUZUKI Scan Tool 1) Connect SUZUKI scan tool to data link connector in the same manner as when making this connection
for DTC check.

and/or P1638 are
detected by ECM
referring to “Diagnostic
Trouble Code (DTC)
Check”. If detected, go

Lamp Does Not Come
ON with Ignition Switch
ON and Engine Stop”.
2 Immobilizer indicator lamp check
Does it immobilizer indicato r lamp flashes on and off
continuously in Step 1? Check ECM for DTC
referring to “Diagnostic
Trouble Code (DTC)
Check”. Then, Go to
applicable DTC diag.
flow.Go to Step 3.
3 Engine start check
Start engine using ignition key.
Does engine start? Go to Step 4.
Perform “Engine and
Emission Control
System Check in
Section 1A”.
4 Immobilizer indicator lamp check
Check Immobilizer indicator la mp remains ON after engine
start.
Does immobilizer indicator la mp remains ON after engine
start? Go to “Immobilizer
Indicator Lamp
Remains ON after
Engine Starts”.
Immobilizer system is
good condition. Then go
