Diagnostic Procedure (Cont’d)
EC-207

DescriptionNJEC0781When the gear position is in “Neutral”, neutral position is “ON”. ECM detects the position because the conti-
nuity of the line (the “ON” signal) exists.
CONSULT-II Reference Value in Data Monitor
Mode
NJEC0782Specification data are reference values.
MONITOR ITEM CONDITION SPECIFICATION
P/N POSI SW Ignition switch: ONShift lever: Neutral ON
Except above OFF
On models not equipped with park/neutral position (PNP) switch, “OFF” is always displayed regardless of gear shift position.
ECM Terminals and Reference ValueNJEC0783Specification 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.

Diagnostic ProcedureNJEC0785
1 CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch “ON”.
2. Select “P/N POSI SW” in “DATA MONITOR” mode with CONSULT-II.
3. Check “P/N POSI SW” signal under the following conditions.
SEF049Y
Without CONSULT-II
1. Turn ignition switch “ON”.
2. Check voltage between ECM terminal 418 and ground under the following conditions.

2 CHECK PNP SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect park/neutral position (PNP) switch harness connector.
SEF393Y
3. Check harness continuity between PNP switch terminal 4 and body ground.Refer to Wiring Diagram.
Continuity should exist.
4. Also check harness for short to power.
OK or NG
OK GO TO 3.
NG Repair open circuit or short to power in harness or connectors.
3 CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 418 and PNP switch terminal 2. 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 4.
NG Repair open circuit or short to ground or short to power in harness or connectors.
4 CHECK PARK/NEUTRAL POSITION (PNP) SWITCH
Refer to MT-21, “Position Switch Check”.
OK or NG
OK GO TO 5.
NG Replace park/neutral position (PNP) switch.
5 CHECK INTERMITTENT INCIDENT
Refer to “TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT”, EC-71.
