DTC P1706 PNP SWITCH

PFP:32006

Component Description

ABS004MM

When the gear position is P or N, park/neutral position (PNP) switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.

CONSULT-II Reference Value in Data Monitor Mode

ABS004MN

Specification data are reference values.

DTC Confirmation Procedure

ABS004MP

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

1.

Turn ignition switch ON.

2.

Select “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II. Then check the “P/N POSI SW” signal under the follow-
ing conditions.

If NG, go to 

EC-598, "Diagnostic Procedure"

 .

If OK, go to following step.

3.

Select “DATA MONITOR” mode with CONSULT-II.

4.

Start engine and warm it up to normal operating temperature.

5.

Maintain the following conditions for at least 60 consecutive sec-
onds.

DTC P1800 VIAS CONTROL SOLENOID VALVE

PFP:14955

Component Description

ABS004MY

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.

least 10 seconds before conducting the next test.

1.

Turn ignition switch ON.

2.

Select “DATA MONITOR” mode with CONSULT-II.
