TRANSMISSION CONTROL MODULE (TCM)
TCM is an electronic circuit component that controls gear shift, idle-up according to the signal from each sensor.
Also it has learning control function for performing optimum control. It is a microcomputer consisting of an IC,
transistor, diode, etc. It is installed behind glove box.

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

AUTOMATIC TRANSMISSION (4 A/T) 7B-25
[INTERMITTENT TROUBLES] and [NOTES ON SYSTEM CIR-
CUIT INSPECTION]
Refer to Section 0A.
DTC CHECK
[Check DTC with SUZUKI scan tool]
1) Turn ignition switch OFF.
2) After setting cartridge, connect SUZUKI scan tool 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 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.
5) After completing the check, turn ignition switch OFF and dis-
connect SUZUKI scan tool from data link connector (DLC)
(1).
[Check DTC without SUZUKI scan tool]
1) Turn ignition switch ON and make sure that O/D OFF lamp is
OFF in combination meter (O/D off switch OFF).
2) Turn ignition switch OFF.
3) Pull out clip (3) and remove glove box (2) from instrument
panel (1).

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).
