DTC P1701 TRANSMISSION CONTROL MODULE (POWER SUPPLY)PFP:31036
DescriptionUCS0062D
When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diag-
nosis memory function stops, malfunction is detected.
NOTE:
Since “P1701 TCM-POWER SUPPLY” will be indicated when replacing TCM, perform diagnosis after
erasing “SELF-DIAG RESULTS”
On Board Diagnosis LogicUCS0062E
This is not an OBD-II self-diagnostic item.
Diagnostic trouble code “P1701 TCM-POWER SUPPLY” with CONSULT-II is detected when TCM does
not receive the voltage signal from the battery power supply.
This is not a malfunction message. (Whenever shutting OFF a power supply to the TCM, this message
appears on the screen.)
Possible CauseUCS0062F
Harness or connectors
(Battery or ignition switch and TCM circuit is open or shorted.)
DTC Confirmation ProcedureUCS0062G
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Wait for at least 2 consecutive seconds.
4. If DTC is detected, go to CVT-147, "
Diagnostic Procedure" .

DTC P1705 THROTTLE POSITION SENSOR
Revision: June 20062007 Versa
DTC P1705 THROTTLE POSITION SENSORPFP:22620
DescriptionUCS0062J
Electric throttle control actuator consists of throttle control motor, accelerator pedal position sensor, throttle
position sensor etc. The actuator sends a signal to the ECM, and ECM sends the signal to TCM with CAN
communication.
CONSULT-II Reference ValueUCS0062K
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS0062L
This is not an OBD-II self-diagnostic item.
Diagnostic trouble code “P1705 TP SEN/CIRC A/T” with CONSULT-II is detected when TCM does not
receive the proper accelerator pedal position signals (input by CAN communication) from ECM.
Possible CauseUCS0062M
ECM
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureUCS0062N
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
