Diagnostic Procedure

Inspection Start
Do you have CONSULT-II?
1. Yes or No
Yes: GO TO 2.

No: GO TO 6.
Check Park/Neutral Position (PNP) Switch Circuit (With Consult-II)
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, 2nd and 1st position switches moving selector lever to each position. Check the signal of the selector lever position is indicated properly.

1. OK or NG
OK: GO TO 7.

NG: GO TO 3.
Detect Malfunctioning Item
Check the following item:
- Park/neutral position (PNP) switch
Check continuity between PNP switch harness connector F94 terminals 1 (G/OR) and 2 (B) and between terminals 3 (OR) and 4 (PU/W), 5 (P/B), 6 (Y/PU), 7 (BR), 8 (G/W), 9 (GY/R) while moving manual shaft through each position.

1. OK or NG
OK: GO TO 5.

NG: GO TO 4.
Check Manual Control Cable Adjustment
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 6 (Without CONSULT- II).
1. OK or NG
OK: Adjust manual control cable. Refer to CONTROL CABLE ADJUSTMENT .

NG: Repair or replace PNP switch.
Detect Malfunctioning Item
Check the following items:
- 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
- Fuse
- Joint connector-3 M29
- Ignition switch
  Refer to POWER DISTRIBUTION .
1. OK or NG
OK: GO TO 7.

NG: Repair or replace damaged parts.
Check Park/Neutral Position (PNP) Switch Circuit (Without Consult-Ii)
Without CONSULT-II
1. Turn ignition switch to ON position. (Do not start engine.)
2. Check voltage between TCM harness connector F50 terminals 26 (PU/R), 27 (P/B), 34 (Y/PU), 35 (G/W), 36 (R/G) and ground while moving selector lever through each position.
