Diagnostic Fault Information
Typical Scan Tool Data
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 9-18 V.
* TCM is not in service mode.
Conditions for Setting the DTC
P0705
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 0.12 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 P0705, P0707, and P0708 are Type A DTCs.
* The TCM freezes transmission adaptive functions.
* If output speed sensor is 0 RPM, Range is drive (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 P0705, P0707, and P0708 are Type A DTCs.
* Voltage of two selector position sensor are within 0.12-4.87 V and sum of two position sensor voltage has deviation within 0.29 V from standard value 5 V.

Circuit/System Verification
1. Ignition ON.
2. Verify there are no other DTCs set.
• If any other DTC are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
• If none DTC are set
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.
3. Ignition ON, observe the scan tool Transmission Range Switch parameter while slowly moving the gear shift lever from Park and through all ranges.
4. Verify the gear shift lever position matches the scan tool parameter.
• If the gear shift lever position does not match with the scan tool parameter
Refer to Transmission Adaptive Functions Transmission Adaptive Functions and Range Selector Lever Cable Adjustment AF40-6 (MDK) - Automatic Transmission.
• If the gear shift lever position matches with the scan tool parameter
5. Operate the vehicle within the Conditions for Running the DTC. It may be helpful to operate the vehicle within the conditions identified from the Freeze Frame/Failure Records data.
6. Verify the DTCs do not set.
• If the DTC is set
Replace the K71 Transmission Control Module.
• If the DTC is not set
7. All OK.
Repair Instructions
