Selector
TROUBLESHOOTING
STEP ACTION YES NO
1 Was “AUTOMATIC TRANSMISSION DIAGNOSTIC FLOW
TABLE” performed?
Go to Step 2. Go to
“AUTOMATIC
TRANSMISSION
DIAGNOSTIC
FLOW TABLE”.
2 Check Transmission Range Sensor 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,
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?
Intermittent
trouble. Check
for intermittent
referring to
“INTERMITTENT
AND POOR
CONNECTION”
in Section 0A.
Go to Step 3.
3 Check Select Cable for Adjustment referring to “SELECT
CABLE” of “ON-VEHICLE SERVICE” in this section.
Is it adjusted correctly?
Go to Step 4. Adjust.
4 Check Transmission Range Sensor.
1) Remove TR sensor from A/ T.
2) At each of P, R, N, D, 2 and L shift position, check continuity
between terminals as well as each terminal and sensor
case. See Fig. 4.
Continuity should be indicated only between those
terminals as shown in Fig. 4 and 5 at each shift position.
Continuity should not exist between any terminal and
sensor case.
Are check results satisfactory?
Go to Step 5. Replace TR
sensor.
5 Check Transmission Range Sensor for Installation Position.
1) Install TR sensor to transmission referring to
“TRANSMISSION RANGE SENSOR” of “ON-VEHICLE
SERVICE” in this section.
2) Perform check as described in step 2 of this table.
Is check result satisfactory?
Transmission
range sensor
maladjusted.
Check “Y”, “Or/B”,
“R”, “Or/ Y”,
“Gr/ R”, “Gr” or
“Gr/ Bl” (G10
engine model)
(“Br/ Y”, “W/B”,
“R/W”, “W/R”,
“Y/R”, “Y/B” or
“R/B” (G13 engine
model)) circuit for
open or short.
If wires and
connections are
OK, substitute a
known-good PCM
and recheck.
