Check transmission range sensor (switch) circuit for 
operation
Check by 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”, “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.

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.

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).
