2. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEARANCE
To check DTC, refer to “DTC CHECK” in this section. When a DTC exists, it means existence of a malfunction in
the system represented by that code but whether it still exists (current) or it occurred in the past and has gone
(history) is unknown. To know it, clear this DTC once (Refer to “DTC CLEARANCE” in this section.), perform
test drive and/or “TROUBLE SYMPTOM CONFIRMATION” in this section and then check DTC again as
described in “DTC CHECK”. Attempt to diagnose the trouble based on the DTC recorded in this step only or fail-
ure to clear the DTC in this step may mislead the diagnosis or make diagnosing difficult. Even after checking the
DTC with the SUZUKI scan tool, diagnosis should be performed according to this flow chart to check TCM for
proper self-diagnosis function.
3 and 4. VISUAL INSPECTION
As a preliminary step, perform visual check of the following items that support proper function of the automatic
transmission.
5.TROUBLE SYMPTOM CONFIRMATION
Check if what the customer claimed in “CUSTOMER COMPLAINT ANALYSIS” 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 the symptom is not actually found, possibility is :
The symptom occurs under certain conditions.
----- Retry with the vehicle under different conditions.
The trouble occurred only temporarily and normal operation has been restored.
----- Perform “DTC CHECK” and if the diagnostic trouble code is indicated, inspect according to the flow
table for that DTC.
6 and 7. RECHECKING AND RECORD OF DTC
Refer to “DTC CHECK” in this section.INSPECTION ITEM REFERRING SECTION
Engine oil ----- level, leakage Section 0B
Engine coolant ----- level, leakage Section 0B
A/T fluid ----- level, leakage, color Section 0B
Battery ----- fluid level, corrosion of terminal
A/T fluid hoses ----- disconnection, looseness, deterioration
Connectors of electric wire harness ----- disconnection, friction Section 8
Fuses ----- burning Section 8
Parts ----- installation, bolt ----- looseness
Parts ----- deformation
Other parts that can be checked visually
Also add following items at engine start.
Indicator, warning lights in combination meter ----- ON
(indicating abnormality in system) or OFFSection 8C
Other parts that can be checked visually

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.

For vehicles equipped with Supplemental Restraint (Air Bag) System :
 Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
 Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
