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 |
1. |
If there are any other transmission DTCs set, diagnose those DTCs first. Refer to
Diagnostic Trouble Code (DTC) List - Vehicle
.
|
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. |
If not within the specified value, refer to
Range Selector Lever Cable Adjustment
and
Transmission Adaptive Functions
.
|
4. |
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.
|
5. |
If not within the specified value, replace the K71 Transmission Control Module.
|
6. |
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.
|
7. |
If the DTC resets, replace the K71 Transmission Control Module.
|
Repair Instructions |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
