TRANSMISSION RANGE SENSOR (SHIFT SWITCH)
Being linked with the selector lever, this sensor changes selector
lever positions into electric signals and send them to the engine
control module. The contact points of this sensor for P and N ranges
are also connected with the starting motor circuit.
So when the selector lever is shifted to the P or N range position,
the contact points for P or N range are connected and cause the
starting motor to operate by turning the starter switch ON.
When the selector lever is in any other position than P and N
ranges, the sensor remains OFF and therefore the starting motor
cannot be operated, that is, the engine cannot be started.
Also, as its contact point for R range is connected with the backup
lamp circuit, only when the selector lever is shifted to R range, the
contact point contacts to light the backup lamp.
DIRECT CLUTCH AND 2ND BRAKE SOLENOID
VALVES
These solenoid valves are mounted on the valve body. They are
turned ON and OFF by the signals from the engine control module
and actuate each shift valve (1 – 2 and 2 – 3 valves) so as to control
transmission gear shift.
Shift solenoid-B (2nd brake solenoid valve) operates 1 – 2 shift
valve, and shift solenoid-A (direct clutch solenoid valve) does 2 –
3 shift valve.

DIAGNOSIS
This vehicle is equipped with an electronic transmission control system, which control the automatic shift up and
shift down timing, 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 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” given below to ob-
tain correct result smoothly.
ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing functions. Refer to Section 6 or 6-1 for details.

When ignition switch is turned ON with engine at a stop malfunc-
tion indicator lamp (MIL) turns ON to check bulb of MIL.

When PCM detects a malfunction in A / T control system (and / or
a malfunction which gives an adverse effect to vehicle emission)
while engine is running, it makes malfunction indicator lamp in
meter cluster of instrument panel turn ON and stores malfunction
area (DTC) in its memory.
If it detects that continuously 3 driving cycles are normal after de-
tecting a malfunction, however, it makes MIL turn OFF although
DTC stored in its memory will remain.

It is possible to communicate with PCM through data link connect-
er (DLC) by using SUZUKI scan tool (Tech-1).
(Diagnostic information can be checked and erased by using a
scan tool)

DTC CONFIRMATION PROCEDURE
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Turn ignition switch OFF and then ON.
2) Clear DTC and warm up engine to normal operating temperature.
3) Shift selector lever to each of P, R, N, D, 2 and L ranges and hold it there for longer than 5 seconds each.
4) Check for DTC and if no DTC appears on display, proceed to the next step.
5) Drive vehicle at 40 mph, 60 km / h or more in 3rd gear of “D” range for longer than 5 sec.
6) Stop vehicle and check DTC.
