Component DescriptionNEEC0424When the gear position is ªNº or ªPº, park/neutral position (PNP)
switch is ªONº.
ECM detects the park/neutral position when continuity with ground
exists.

ECM Terminals and Reference ValueNEEC0426Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC Confirmation Procedure=NEEC0428CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 5 seconds
before conducting the next test.
With CONSULT-II
1) Turn ignition switch ON.
SEF213Y
2) Select ªP/N POSI SWº in ªDATA MONITORº mode with CON-
SULT-II. Then check the ªP/N POSI SWº signal under the fol-
lowing conditions.
Position (Selector lever) Known-good signal
ªNº ON
Except the above position OFF
If NG, go to ªDiagnostic Procedureº, EC-3359.
If OK, go to following step.
3) Select ªDATA MONITORº 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
seconds.
ENG SPEED 1,400 - 4,000 rpm
COOLAN TEMP/S More than 70ÉC (158ÉF)
B/FUEL SCHDL 3.5 - 17 msec
