Code 1003

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
- 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.

OR

Without Consult
(1) Turn ignition switch "ON".
(2) Check voltage between ECM terminal (22) and body ground in the following conditions.
