Wiring Diagram
Refer to “DTC P0705: Transmission Range Sensor Circuit Malfunction (P R N D L Input)”.
DTC Detecting Condition and Trouble Area
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Do you have SUZUKI scan tool? Go to Step 3. Go to Step 4.
3 Check transmission range sensor circuit
Check by using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch
turned OFF.
2) Turn ignition switch to ON position and then check
transmission range signal (“P”, “R”, “N”, “D”, “3”, “2” or
“L”) on display when shifting select lever to each range.
Is applicable range indicated?
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”. Go to Step 5.
4 Check transmission range sensor circuit for operation
Check by not using SUZUKI scan tool:
1) Turn ignition switch to ON position.
2) Check voltage at terminals “C07-1”, “C07-7”, “C07-8”,
“C07-18”, “C07-19” and “C07-20” respectively with
select lever shifted to each range.
Taking terminal “C07-19” as an example, is battery
voltage will be indicated only when select lever is shifted
to “2” 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
referring to “Intermittent
and Poor Connection
Inspection in Section
00”. Go to Step 5.
5 Check transmission range sensor
1) Check transmission range sensor referring to
“Transmission Range Sensor Inspection and
Adjustment”.
Are check results satisfactory?
“PNK/BLK”, “RED”,
“GRN/ORN”, “GRN/
YEL”, “GRN” or “LT
GRN/BLK” circuit
shorted to power circuit
or shorted each other. If
wires are OK, substitute
a know-good TCM and
recheck. Replace Transmission
range sensor.
