2
Vehicle moves in N position
DESCRIPTION
•  Vehicle creeps in N position.
•  Vehicle creeps if brake pedal is not depressed in N position.
POSSIBLE CAUSE
•  If the vehicle moves in N position, basically, the malfunction is in the ATX. Since a malfunction in the sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the related wiring harnesses.
1.  Clutch burnt (Forward clutch)
•  Control valve body malfunction
2.  Selector lever position disparity (Although the selector indicator shows N position, the hydraulic circuit shows D range or R position)
Note
•  Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.
