2. Select "DATA MONITOR" mode for "A/T" with CONSULT-II.
3. Read out P/N, R, D, 2nd position switches moving selector lever to each position.

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

   NOTE: "2 POSITION SW" indicates L position status.

OK or NG 

1. OK: GO TO  8.
2. NG: GO TO 3.

Check the following item:

• Park/neutral position (PNP) switch

  Check continuity between PNP switch harness connector F29 terminals 1 and 2 and between terminals 3 and 5, 6, 7, 8 and 9 while moving manual shaft through each position.

OK or NG 

1. OK: GO TO  6.
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 2 (With CONSULT-II) or 7 (With out CONSULT-II).

OK or NG 

1. OK: Adjust manual control cable. Refer to "CONTROL CABLE ADJUSTMENT "
2. NG: GO TO 5.

Remove PNP switch from A/T assembly and check continuity of PNP switch terminals. Refer to test group 3.

OK or NG 

1. OK: Adjust PNP switch. Refer to "PARK/NEUTRAL POSITION (PNP) SWITCH ADJUSTMENT ".
2. NG: Repair or replace PNP switch.

Check the following items:

• Fuse
• Harness for short or open between ignition switch and park/neutral position (PNP) switch
• Harness for short or open between park/neutral position (PNP) switch and TCM
• Harness for short or open between park/neutral position (PNP) switch and combination meter
• Harness for short or open between combination meter and TCM
• Ignition switch

  Refer to "POWER DISTRIBUTION "

OK or NG 

1. OK: GO TO  8.
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 harness connector E143 terminals 27 (P/B), 34 (G), 35 (G/W), 36 (R/G) and ground while moving selector lever through each position.

OK or NG 

1. OK: GO TO 8.
2. NG: GO TO  3.

Perform "DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE "

OK or NG 

1. OK: INSPECTION END 
2. NG: GO TO 9.

1. perform TCM input/output signal inspection. Refer to "TCM TERMINALS AND REFERENCE VALUE ".
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

OK or NG 

1. OK: INSPECTION END 
2. NG: Repair or replace damaged parts.
