Description
EBS015D2
When the gear position is in Neutral, park/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
EBS015D3
Specification data are reference values.
ECM Terminals and Reference Value
EBS015D4
Specification 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 Procedure
EBS015D6
1.
CHECK OVERALL FUNCTION
With CONSULT-II
1.
Turn ignition switch ON.
2.
Select “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II.
3.
Check “P/N POSI SW” signal under the following conditions.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 2.
2.
CHECK PNP SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect park/neutral position (PNP) switch harness connec-
tor.
3.
Check harness continuity between PNP switch terminal 2 and
ground.
Refer to Wiring Diagram.
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 con-
nectors.
3.
CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Disconnect ECM harness connector.
2.
Check harness continuity between ECM terminal 110 and PNP switch terminal 1.
Refer to Wiring Diagram.
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 SWITCH
Refer to
