    2. Turn the ignition switch to the ON position.

    CHECK:

    Measure the voltage according to the value(s) in the table below when the shift position is adjusted into each position.

    OK:

    PARK/NEUTRAL POSITION SWITCH CONNECTOR VOLTAGE SPECIFICATION

    Shift Position Tester connection Specified condition
    P and N E7 - 8 (NSW) - Body ground Below 1 V
    Except P and N E7 - 8 (NSW) - Body ground 10 to 14 V
    R E5 - 11 (R) - Body ground 10 to 14 V*
    Except R E5 - 11 (R) - Body ground Below 1 V
    D E5 - 10 (D) - Body ground 10 to 14 V
    Except D E5 - 10 (D) - Body ground Below 1 V
    2 E5 - 9 (2) - Body ground 10 to 14 V
    Except 2 E5 - 9 (2) - Body ground Below 1 V
    L E5 - 8 (L) - Body ground 10 to 14 V
    Except L E5 - 8 (L) - Body ground Below 1 V
    NOTE: *: The voltage will drop slightly due to lighting up of the back up light.
    1. NG: Repair or replace the harness or connector (  HOW TO USE THE DIAGNOSTIC CHART AND INSPECTION PROCEDURE  ). 
    2. OK: Replace the ECM.
