performed?
2 Check 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?
3 Check 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?

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, 2) Check voltage at terminals C03-3 C03-4 C03-5 C03-14
C03-15 and C03-16 for G10 engine model (C02-11, C02-12,
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?
Check voltage at other terminals likewise, referring to Fig. 3.
Are check results satisfactory?
