SYMPTOM:
Vehicle moves forward or backward when selecting “N” position.
1.CHECK PNP SWITCH CIRCUIT
With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage to PNP switch circuit?
Without CONSULT-II
Does self-diagnosis show damage to PNP switch circuit?
Ye s o r N o
Yes >> Check PNP switch circuit. Refer to AT- 3 3 3 , "21. TCM
Self-diagnosis Does Not Activate (PNP & Overdrive
Control Switches, and Throttle Position Sensor Circuit
Checks)" .
No >> GO TO 2
2.CHECK CONTROL CABLE
Check control cable. Refer to AT-408, "
Control Cable Adjustment" .
OK or NG
OK >> GO TO 3
NG >> Adjust control cable. Refer to AT- 4 0 8 , "
Control Cable
Adjustment" .
3.CHECK A/T FLUID LEVEL
Check A/T fluid level again.
OK or NG
OK >> GO TO 4
NG >> Refill ATF.
