Circuit/System Description
Shift position switch function is installed as one part of
transmission control module (TCM). The position switch consists of
2 switches, whose values are running in the opposite direction.
Automatic transmission shift range is calculated by TCM reading
output voltage from gear lever position sensor installed in TCM
itself.
Conditions for Running the DTC
| • |
Ignition voltage is 6-15.5
V. |
| • |
TCM is not in service
mode. |
Conditions for Setting the DTC
P0706
Sum of two position sensor voltage has deviation over 0.29 V from
standard value 5 V.
P0707
Voltage on position switch 1 and position switch 2 is less than
0.127 V for 100 ms continuously after 2 consecutive times.
P0708
Voltage on position switch 1 and position switch 2 is more than
4.87 V for 100 ms continuously after 2 consecutive times.
Action Taken When the DTC Sets
| • |
DTCs P0706, P0707, and P0708
are Type A DTCs. |
| • |
The TCM freezes transmission
adaptive functions. |
| • |
If output speed sensor is 0
RPM, Range is D, 2nd gear is hold and service mode will be
set. |
| • |
The engine start is locked
after engine has stopped. |
Conditions for Clearing the DTC
| • |
DTCs P0706, P0707, and P0708
are Type A DTCs. |
| • |
Voltage of two selector
position sensor are within 0.127-4.87 V and sum of two position
sensor voltage has deviation within 0.29 V from standard value 5
V. |

Circuit/System Verification
|
Note: It is
especially important to closely observe the Park and Neutral to
Drive transitional positions while moving the shift lever and
observing for possible misalignment or slack in the shifter
mechanism.
|
| 2. |
Ignition ON, observe the scan
tool Transmission Range Switch parameter while slowly moving the
gear shift lever from Park and through all ranges. Verify the gear
shift lever position matches the scan tool parameter. |
| 3. |
Ignition ON, observe the scan
tool Transmission Range Switch parameter while slowly moving the
gear shift lever from Park and through all ranges. Verify the gear
shift lever position matches the scan tool parameter. |
| ⇒ |
If not within the specified value, replace the K71
Transmission Control Module. |
| 4. |
Operate the vehicle within the
Conditions for Running the DTC to verify the DTC does not reset.
You may also operate the vehicle within the conditions that you
observed from the Freeze Frame/Failure Records data. |
| ⇒ |
If the DTC resets, replace the K71 Transmission
Control Module. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
TCM-Refer to
Control Module References for replacement, setup and
programming.
