Dtc P0707: Transmission Range Sensor Circuit Low - Suzuki 2006 SX4 Service Manual

5A-38 Automatic Transmission/Transaxle:
DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Do you have SUZUKI scan tool?
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?
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?
5 Check transmission range sensor
1) Check transmission range sensor referring to
"Transmission Range Sensor Inspection and
Adjustment".
Are check results satisfactory?
