OUTPUT SHAFT SPEED SENSOR (A / T VSS)
The output shaft speed sensor consists of a magnetic core with
magnet and coil. It is mounted on transmission case with 0.6 mm
(0.024 in.) air gap between the core end and countershaft gear
tooth.
While the countershaft rotates, magnetic flux is cut by gear tooth
thus a pulse is generated in the sensor coil according to the speed.
And then, the pulse is transmitted to engine control module as
speed signal.
AUTOMATIC SHIFT DIAGRAM
Automatic shift schedule as a result of shift control is shown below. In case that selector lever is shifted to L range
at a higher than 37 km / h (23 mile / h) (G10 engine model), 40 km / h (25 mile / h) (G13 engine model) speed, 2nd
gear is operated and then down shifts to 1st at a speed lower than that. No up shift is available in L range.

AUTOMATIC TRANSMISSION BASIC CHECK
This check is very important for troubleshooting when PCM (ECM) has detected no DTC and no abnormality has
been found in visual inspection. Follow the flow table carefully.
STEPACTIONYESNO
1Was “AUTOMATIC TRANSMISSION DIAG. FLOW TABLE”
performed?Go to Step 2.Go to
“AUTOMATIC
TRANSMISSION
DIAG. FLOW
TABLE”.
2Check A / T Fluid.
Warm transmission to normal operating temperature and check
fluid level and contamination referring to “FLUID LEVEL
CHECK” of “ON-VEHICLE SERVICE” in this section.
Is it in good condition?Go to Step 3.Add or change
fluid.
3Check Fluid Pressure Control Cable.
1) Warm up engine to normal operating temperature.
2) Check fluid pressure control cable for play referring to
“FLUID PRESSURE CONTROL CABLE” of “ON-VEHICLE
SERVICE” in this section.
Is it in good condition?Go to Step 4.Adjust.
4Check Select Cable for Adjustment referring to “SELECT
CABLE” of “ON-VEHICLE SERVICE” in this section.

5Check Transmission Range Sensor (Switch) Circuit for
Operation.
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
2) Turn ignition switch ON and check transmission range
signal (P, R, N, D, 2 or L) on display when shifting manual
selector to each range. See Fig. 1.
Is applicable range indicated?
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals C03-3 C03-4 C03-5 C03-14
Go to Step 6.Go to Step 3 of
DTC P0705
Flow Table.
2) Check voltage at terminals C03-3, C03-4, C03-5, C03-14,

C02-14, C02-15, C02-21 and C02-23 for G13 engine
model) respectively with selector lever shifted to each
range. See Fig. 2.
Taking terminal C03-3 for G10 engine model (C02-11 for
G13 engine model) as an example, is battery voltage
indicated only when selector lever is shifted to “2” range and
0 V for other ranges as shown in Fig. 3?
