Diagnostic ProcedureUCS005Z2
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis check. Refer to CVT-60, "
SELF-DIAGNOSTIC RESULT MODE" .
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated?
YES >> Check CAN communication line. Refer to CVT-68, "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK STOP LAMP SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Read out ON/OFF switching action of the “BRAKE SW”.
OK or NG
OK >>INSPECTION END
NG >> GO TO 3.
3. CHECK STOP LAMP SWITCH
Check continuity between stop lamp switch harness connector E13
terminals 1 and 2. Refer to CVT-176, "
Wiring Diagram — CVT —
NONDTC" .
Check stop lamp switch after adjusting brake pedal — refer to
BR-6, "
BRAKE PEDAL" .
OK or NG
OK >> Check the following. If NG, repair or replace damaged
parts.

Harness for short or open between battery and stop lamp switch.

Harness for short or open between stop lamp switch and combination meter.

DTC P0705 PARK/NEUTRAL POSITION SWITCH
Revision: June 20062007 Versa
DTC P0705 PARK/NEUTRAL POSITION SWITCHPFP:32006
DescriptionUCS005Z3

The PNP switch is included in the control valve assembly.

The PNP switch includes 4 transmission position switches.

TCM judges the selector lever position by the PNP switch signal.
CONSULT-II Reference ValueUCS005Z4
On Board Diagnosis LogicUCS005Z5

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0705 PNP SW/CIRC” with CONSULT-II is detected under the following condi-
tions.
–When TCM does not receive the correct voltage signal from the PNP switches 1, 2, 3 and 4 based on the
gear position.
–When the signal from monitor terminal of PNP switch 3 is different from PNP switch 3.
Possible CauseUCS005Z6

Harness or connectors
(PNP switches 1, 2, 3, 4 and TCM circuit is open or shorted.)

PNP switches 1, 2, 3, 4

PNP switch 3 monitor terminal is open or shorted
DTC Confirmation ProcedureUCS005Z7
CAUTION:
Always drive vehicle at a safe speed.
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, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
