DTC P1720 VSS

PFP:31036

Description

NBS003C0

NOTE:

●

If DTC P1720 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to

EC-151, "DTC U1000, U1001 CAN COMMUNICATION LINE"

●

If DTC P1720 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to

EC-154, "DTC U1010 CAN COMMUNICATION"

ECM receives two vehicle speed signals via CAN communication line. One is sent from “ABS actuator and
electric unit (control unit)” via “unified meter and A/C amp.”, and the other is from TCM (Transmission control
module). ECM uses these signals for engine control.

CAUTION:

Always drive vehicle at a safe speed.

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.

WITH CONSULT-II

Turn ignition switch ON.

Select “DATA MONITOR” mode with CONSULT-II.

Start engine.

Drive vehicle at a speed of 20 km/h (12 MPH) or more for at
least 5 seconds without brake pedal depressing.

DTC P1800 VIAS CONTROL SOLENOID VALVE

Revision: 2006 July

2007 Murano

DTC P1800 VIAS CONTROL SOLENOID VALVE

PFP:14955

Component Description

NBS003C5

The VIAS control solenoid valve cuts the intake manifold vacuum
signal for power valve control. It responds to ON/OFF signals from
the ECM. When the solenoid is OFF, the vacuum signal from the
intake manifold is cut. When the ECM sends an ON signal the coil
pulls the plunger downward and feeds the vacuum signal to the
power valve actuator.

Component Description

NBS0037M

Power supply for the throttle control motor is provided to the ECM via throttle control motor relay. The throttle
control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends
an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition
switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not
provided to the ECM.

Specification data are reference values.

On Board Diagnosis Logic

NBS0037O
