Diagnostic Procedure

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/N , R , D , 2 and 1 position switches moving selector lever to each position. Check the signal of the selector lever position is indicated properly.

OK or NG 

1. OK: GO TO  3.
2. NG: Check the following items:
   • PNP switch Refer to COMPONENT INSPECTION .
   • Harness for short or open between ignition switch and PNP switch (Main harness)
   • Harness for short or open between PNP switch and TCM (Main harness)
   • Ignition switch and fuse Refer to POWER DISTRIBUTION .

Without CONSULT-II 

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