Do you have CONSULT-II?

Yes or No

• Yes: GO TO 2.
• No: GO TO  5.

With CONSULT-II 

1. Turn ignition switch to ON position. (Do not start engine.)
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

• OK: GO TO  8.
• 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

• OK: GO TO  6.
• NG: GO TO 4.

Check PNP switch again with manual control cable disconnected from manual shaft of A/T assembly. Refer to Step 2 (With CONSULT-II) or Step 7 (With out CONSULT-II).

OK or NG

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

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

OK or NG

• OK: Adjust PNP switch. Refer to "PARK/NEUTRAL POSITION (PNP) SWITCH ADJUSTMENT ".
• 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 SUPPLY ROUTING CIRCUIT ".

OK or NG

• OK: GO TO  8.
• 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.

   0: 0V 

OK or NG

• OK: GO TO 8.
• NG: GO TO  3.

Perform "DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE ".

OK or NG

• OK: INSPECTION END 
• 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

• OK: INSPECTION END 
• NG: Repair or replace damaged parts.
