2. No: GO TO  6.

With CONSULT-II 

1. Turn ignition switch to ON position.

   Check that the signal of the selector lever position is indicated properly.

OK or NG 

1. OK: GO TO  7.
2. NG: GO TO 3.

Check the following item:

• Park/neutral position (PNP) switch

  Check continuity between park/neutral position (PNP) switch F29 terminals 1 (G/OR) and 2 (B) and between terminals 3 (Y) and 4 (OR), 5 (L), 6 (W/G), 7 (BR/W), 8 (G/W) and 9 (G) while moving manual shaft through each position.
