dtc 34 NISSAN PRIMERA 1999 Electronic Repair Manual

Component DescriptionNCEC0424When the gear position is ªPº (CVT models only) or ªNº, park/
neutral position (PNP) switch is ªONº.
ECM detects the park/neutral position when continuity with ground
exists.

Component Description
EC-298

With CONSULT-II
1) Turn ignition switch ªONº.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Start engine and warm it up to normal operating temperature.
4) Maintain the following conditions for at least 50 consecutive
seconds.
ENG SPEED 1,500 - 3,400 rpm
COOLAN TEMP/S More than 70ÉC (158ÉF)
B/FUEL SCHDL 2.4 - 12.0 msec
VHCL SPEED SE 64 - 130 km/h (40 - 81 MPH)
Selector lever Suitable position
5) If 1st trip DTC is detected, go to ªDiagnostic Procedureº, EC-
SR-301.
Overall Function CheckNCEC0429Use this procedure to check the overall function of the park/neutral
position switch circuit. During this check, a 1st trip DTC might not
be confirmed.
Without CONSULT-II
1) Turn ignition switch ªONº.
2) Check voltage between ECM terminal 42 (PNP switch signal)
and body ground under the following conditions.
Condition (Gear position) Voltage (V) (Known good data)
ªPº (CVT only) and ªNº position Approx. 0
Except the above position BATTERY VOLTAGE (11 - 14V)
3) If NG, go to ªDiagnostic Procedureº, EC-SR-301.

Diagnostic ProcedureNCEC0431
1 CHECK GROUND CIRCUIT
1. Turn ignition switch ªOFFº.
2. Disconnect PNP switch harness connector.
SEF740W3. Check harness continuity between PNP switch harness connector terminal 2 and body ground.
Refer to wiring diagram.
Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 3.
NG©GO TO 2.
2 DETECT MALFUNCTIONING PART
Check the harness for open or short between PNP switch and body ground.
©Repair open circuit or short to ground or short to power in harness or connectors.
3 CHECK INPUT SIGNAL CIRCUIT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 42 and PNP switch harness connector terminal 1.
Refer to wiring diagram.
Continuity should exist.
3. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 5.
NG©GO TO 4.
4 DETECT MALFUNCTIONING PART
Check the harness for open or short between ECM and PNP switch.
©Repair open circuit or short to ground or short to power in harness or connectors.
5 CHECK PNP SWITCH
Refer to MT section or AT section.
OK or NG
OK©GO TO 6.
NG©Replace PNP switch.
6 CHECK INTERMITTENT INCIDENT
Perform ªTROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENTº, EC-SR-114.
