COMPONENT DESCRIPTION
When the gear position is in "P" (A/T models only) or "N", park/neutral position is "ON". ECM detects the position because the continuity of the line (the "ON" signal) exists.




CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Specification data are reference values.




ECM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values, and are measured between each terminal and (25) (ECCS ground) with a voltmeter.




ON BOARD DIAGNOSIS LOGIC

OVERALL FUNCTION CHECK
This procedure can be used for checking the overall function of the park/neutral position switch circuit. During this check, a DTC might not be confirmed.

With Consult
(1) Turn ignition switch "ON".




(2) Perform "PARK/NEUT POSI SW CKT" in "FUNCTION TEST" mode with CONSULT.

OR

With Consult




(2) Select "P/N POSI SW" in "DATA MONITOR" mode with CONSULT.
(3) Check the "P/N POSI SW" signal in the following conditions.

Condition (Gear Position) / Known good signal
"P" (AT only) and "N" position / ON
Except the above position / OFF


OR

Without Consult
(1) Turn ignition switch "ON".




(2) Check voltage between ECM terminal (22) and body ground in the following conditions.

Condition (Gear position) / Voltage (V) (Known good data)
"P" (AT only) and "N" position / Approx. 0
Except the above position / Approx. 5
