OFF.

2) Turn ignition switch ON and check transmission range

signal (“P”, “R”, “N”, “D”, “3” or “L”) on display when
shifting select lever to each range.

Is applicable range indicated?

Intermittent trouble.
Check for intermittent
trouble to “Intermittent
and Poor Connection
Inspection in Section
00”.

Go to Step 5.

4

Check transmission range sensor (switch) circuit for
operation
Check without using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals “E93-1”, “E93-8”, “E93-8”,

“E93-18”, “E93-19” and “E93-20” respectively with select
lever shifted to each range.
Taking terminal “E93-1” as an example, is battery
voltage will be indicated only when shift lever is shifted to
“R” range and 0 V for other ranges as shown in table.
Check voltage at other terminals likewise, referring to
table.

Are check results satisfactory?

Intermittent trouble.
Check for intermittent
trouble referring to
“Intermittent and Poor
Connection Inspection
in Section 00”.

Go to Step 5.

S6JB0B5104022

DTC Detecting Condition and Trouble Area

DTC Confirmation Procedure

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Shift select lever to “D” range.
5) Start vehicle and increase vehicle speed to 50 km/h (31 mile/h) or more with throttle position 10% for 30 minutes.
6) Stop vehicle and turn ignition switch OFF.
7) Repeat Step 3) to 4) one time.
8) Stop vehicle.
9) Check DTC, pending DTC and freeze-frame data.

5

Check transmission range sensor (switch) for
installation position
1) Check transmission range sensor (switch) for installation

position referring to “Transmission Range Sensor
Inspection and Adjustment”.

Is it adjusted correctly?

Go to Step 6.

Adjust transmission
range sensor (switch)
and recheck.

6

Check select cable for adjustment
1) Check select cable for adjustment referring to “Select

Cable Adjustment”.

Is it adjusted correctly?

Go to Step 7.

Adjust select cable and
recheck.

7

Check transmission range sensor (switch)
1) Check transmission range sensor (switch) referring to

“Transmission Range Sensor Inspection and
Adjustment”.

Are check results satisfactory?

Transmission range
sensor circuit open or
shorted to ground. If
wires and connections
are OK, substitute a
known-good TCM and
recheck.

Replace transmission
range sensor (switch).
