LEARNING CONTROL INITIALIZATION
When one or more operations such as shown below are per-
formed, all learned contents which are stored in TCM memory
should be erased after the operations.
Replacing transmission with new or used one.
Repairing transmission partially by replacing any brake com-
ponent parts with new and/or used brake disc(s), plate(s)
and/or flange.
Repairing transmission partially by replacing any clutch com-
ponent parts with new and/or used clutch disc(s), plate(s)
and/or flange.
Replacing TCM with used one.
1) Turn ignition switch ON, leaving engine OFF.
2) Using service wire, connect diagnosis switch terminal (2)
with ground terminal (3) of monitor connector No.2 (1).
3) Shift selector lever from “D” range to “2” range 3 times
repeatedly within 10 seconds with diagnosis switch terminal
(2) kept on connecting with ground.
4) Check DTC referring to “DTC CHECK” in this section and
confirm that only DTC No.12 is displayed.
If not, repeat Step 1) to Step 3) and check again.
BRAKE INTERLOCK SYSTEM (IF EQUIPPED)
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and
interlock cable control system.
The shift lock solenoid control system is so designed that the
selector lever can not be shifted from “P” range position unless
ignition switch is turned ON and the brake pedal is depressed.
And interlock cable control system is so designed that select lever
cannot be shifted from “P” range position unless ignition switch is
turned to “ACC” or “ON” position. Also, ignition key cannot be
pulled out of key slot unless selector lever is in “P” range. NOTE:
 “O/D OFF” lamp lights during initializing.
 Diagnostic trouble code(s) (DTC(s)) also are erased by
performing this initializing procedure.
 After initializing is achieved, DTC No.12 is stored in
TCM. If initializing is failed, DTC No.52 is stored in
TCM.

DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(IMMOBILIZER CONTROL MODULE)
1) Turn ignition switch OFF.
2) After setting cartridge to Suzuki scan tool, connect it to data
link connector (DLC) (1) located on underside of instrument
panel at driver’s seat side.
Special tool
(A) : 09931-76011 (Suzuki scan tool)
(B) : Mass storage cartridge
(C) : 09931-76030 (16/14 pin DLC cable)
3) Turn ignition switch ON.
4) Read DTC stored in immobilizer control module 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 immobilizer
control module is not possible, go to “Diagnostic Flow Table
C”.
5) After completing the check, turn ignition switch OFF and dis-
connect Suzuki scan tool from data link connector (DLC). NOTE:
When reading DTC stored in immobilizer control module
using Suzuki scan tool, select “BCM” from the applica-
tions menu and “IMMOBILIZER” from the select system
menu displayed on Suzuki scan tool.

8G-8 IMMOBILIZER CONTROL SYSTEM
DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(ECM)
1) Turn ignition switch OFF.
2) After setting cartridge to Suzuki scan tool, connect it to data
link connector (DLC) (1) located on underside of instrument
panel at driver’s seat side.
Special tool
(A) : 09931-76011 (Suzuki scan tool)
(B) : Mass storage cartridge
(C) : 09931-76030 (16/14 pin DLC cable)
3) Turn ignition switch ON.
4) Read DTC stored in ECM 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 ECM is not
possible, check if Suzuki scan tool is communicable by con-
necting it to ECM 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 communication was not possible.
5) After completing the check, turn ignition switch OFF and dis-
connect Suzuki scan tool from data link connector (DLC). NOTE:
When reading DTC stored in ECM using Suzuki scan
tool, select “ECM” from the applications menu and
“SUZUKI mode” from the communication mode menu
displayed on Suzuki scan tool.
If ECM detects a trouble in both engine and emission
control system and immobilizer control system, Suzuki
scan tool indicates trouble codes of both systems
using Suzuki mode of ECM application.
