Diagnostic Procedure

Do you have CONSULT-II? 

Yes or No

1. Yes: GO TO 2.
2. No: GO TO  6.

With CONSULT-II 

1. Turn ignition switch to ON position.

   (Do not start engine.)

2. Select "TCM INPUT SIGNALS" in "DATA MONITOR" mode for "A/T" with CONSULT-II.
3. Read out P, R, N, D, 2 and 1 position switches moving selector lever to each 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) and 2 (G) and between terminals 3 (GY) and 4 (PU/W), 5 (P/B), 6 (G), 7 (BR), 8 (G/W) and 9 (GY/R) while moving manual shaft through each position.

OK or NG

1. OK: GO TO  5.
2. NG: GO TO 4.

Check PNP switch again with manual control cable disconnected from manual shaft of A/T assembly. Refer to test group 1.

OK or NG

1. OK: Adjust manual control cable. Refer to "CONTROL CABLE ADJUSTMENT ".
2. NG: Repair or replace PNP switch.

Check the following items:

• Harness for short or open between ignition switch and park/neutral position (PNP) switch (Main harness)
• Harness for short or open between park/neutral position (PNP) switch and TCM (Main harness)
• Fuse
• Ignition switch
• Refer to "POWER SUPPLY ROUTING CIRCUIT ".

OK or NG

1. OK: GO TO  7.
2. NG: Repair or replace damaged parts.

Without CONSULT-II 

1. Turn ignition switch to ON position. (Do not start engine.)
2. Check voltage between TCM terminals 26 (PU/W), 27 (P/B), 34 (G), 35 (G/W), 36 (R/B) and ground while moving selector lever through each position.
