AUTOMATIC TRANSMISSION (4 A/T) 7B1-7
Diagnosis
This vehicle is equipped with an electronic transmission control system, which control the automatic shift up and
shift down timing, TCC operation, etc. suitably to vehicle driving conditions.
PCM (ECM) has an On-Board Diagnosis system which detects a malfunction in this system and abnormality of
those parts that influence the engine exhaust emission.
When diagnosing a trouble in the transmission including this system, be sure to have full understanding of the
outline of “ON-BOARD DIAGNOSTIC SYSTEM” and each item in “PRECAUTION IN DIAGNOSING TROUBLE”
and execute diagnosis according to “AUTOMATIC TRANSMISSION DIAGNOSTIC FLOW TABLE” to obtain
correct result smoothly.
On-Board Diagnostic System (Vehicle without
monitor connector)
For automatic transmission control system, PCM (ECM) has fol-
lowing functions. Refer to Section 6-1 for details.
•When the ignition switch is turned ON with the engine at a
stop, malfunction indicator lamp (MIL) (1) turns ON to check
the bulb of the MIL.
•When PCM detects a malfunction in A/T control system
(and/or a malfunction which gives an adverse effect to vehi-
cle emission) while the engine is running, it makes the mal-
function indicator lamp in the meter cluster of the instrument
panel turn ON and stores the malfunction area.
(If it detects that continuously 3 driving cycles are normal
after detecting a malfunction, however, it makes MIL (1) turn
OFF although DTC stored in its memory will remain.)
•It is possible to communicate through DLC (3) by using not
only SUZUKI scan tool (2). (Diagnostic information can be
accessed by using a scan tool (2).)
2 DRIVING CYCLE DETECTION LOGIC
Refer to Section 6-1 for details.
PENDING DTC
Refer to Section 6-1 for details.
FREEZE FRAME DATA
Refer to Section 6-1 for details.

7B1-8 AUTOMATIC TRANSMISSION (4 A/T)
On-Board Diagnostic System (Vehicle with
monitor connector)
For automatic transmission control system, PCM (ECM) has fol-
lowing functions. Refer to Section 6/6-1 for details.
•When the ignition switch is turned ON with the engine at a
stop, malfunction indicator lamp (MIL) turns ON to check the
bulb of the MIL.
•When PCM detects a trouble in electronic shift control sys-
tem, it stores its trouble code in ECM back-up memory. (The
memory is kept as it is even if the trouble was only tempo-
rary and disappeared immediately. And it is not erased
unless the power to PCM is shut off for 30 seconds or
longer.)
•It is possible to communicate through DLC by using not only
SUZUKI scan tool (2) but also generic scan tool. (Diagnostic
information can be accessed by using a scan tool.)
•ECM also indicates trouble area in memory by means of
flashing of malfunction indicator lamp (1) at the time of
inspection. (i.e. when diagnosis switch terminal (3) is con-
nected to ground terminal (4) with a service wire (5) and igni-
tion switch is turned ON.)

Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a inspection form will facilitate collecting information to the point required for
proper analysis and diagnosis.
STEP 2. DIAGNOSTIC TROUBLE CODE (DTC)/FREEZE FRAME DATA CHECK, RECORD AND
CLEARANCE
First, referring to DTC check section, check DTC (including pending DTC). If DTC exists, print or write down
DTC and freeze frame data and then clear them by referring to DTC clearance section. DTC indicates malfunc-
tion in the system but it is not possible to know from it whether the malfunction is occurring now or it occurred in
the past and normal condition has been restored. In order to know that, check symptom in question according to
Step 5 and then recheck DTC according to Step 6.
Diagnosing a trouble based on the DTC in this step only or failure to clear the DTC in this step may result in an
faulty diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting which is otherwise unneces-
sary.
