7B1-18 AUTOMATIC TRANSMISSION (4 A / T)
[For Vehicle without Monitor Connector]
ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing 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 malfunction in A / T control system (and / or
a malfunction which gives an adverse effect to vehicle emission)
while the engine is running, it makes the malfunction indicator
lamp in the meter cluster of the instrument panel turn ON and
stores the malfunction area in its memory. (If it detects that contin-
uously 3 driving cycles are normal after detecting a malfunction,
however, it makes MIL turn OFF although DTC stored in its
memory will remain.)

It is possible to communicate through DLC by using not only SU-
ZUKI scan tool (Tech-1) but also generic scan tool. (Diagnostic in-
formation can be accessed by using a scan tool.)

ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing 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 system, it
stores its trouble code in back-up memory in itself. (The memory
is kept as it is even if the trouble was only temporary and disap-
peared 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 SU-
ZUKI scan tool (Tech-1) but also generic scan tool. (Diagnostic in-
formation can be accessed by using a scan tool.)

It is also possible to communicate by not using scan tool. PCM
indicates trouble area in memory by means of flashing of malfunc-
tion indicator lamp at the time of inspection (i.e. when diagnosis
switch terminal is grounded and ignition switch is turned ON).

MALFUNCTION INDICATOR LAMP (MIL) CHECK
Refer to the same item in Section 6 / 6-1 for checking procedure.
ªO / D OFFº LAMP CHECK
1) Check that O / D cut switch button is at OFF position (pushed).
2) Turn ignition switch ON.
3) Check that ªO / D OFFº lamp lights for about 2 ± 4 sec. and then goes OFF.
If anything faulty is found, advance ªDiagnostic flow table B-1 or B-2º O / D OFF ªLAMP CIRCUIT CHECKº.
ªPOWERº LAMP CHECK
1) Check that Power / Normal change switch button is at Normal position.
2) Turn ignition switch ON.
3) Check that ªPowerº Lamp light for 2 ± 4 sec. and then goes OFF.
If anything faulty is found, advance ªDiagnostic flow table B-3 or B-4 ªPOWERº LAMP CIRCUIT CHECK 2.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK
Refer to the same item in Section 6 / 6-1 for checking procedure.
