Vehicle does not move in D, S, L ranges, or in R position
|
DESCRIPTION
|
• Vehicle does not move when AP depressed.
|
POSSIBLE CAUSE
|
• If the vehicle does not move in D, S, L ranges or R position, basically, the malfunction is in the ATX. (Vehicle will move even with a malfunction in the PCM.) Since a malfunction is in the sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the related harnesses.
