NO.1 VEHICLE DOES NOT MOVE IN D, S, L RANGES, OR IN R POSITION
1 Vehicle does not move in D, S, L ranges, or in R position
DESCRIPTION • Vehicle does not move when AP depressed.
• 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.
1. Clutch slipped, worn (D, S, L ranges-Forward clutch, R position-Reverse clutch, Low and reverse
brake)
• Line pressure low
• Shift solenoid D malfunction
• Shift solenoid E malfunction
• Shift solenoid A malfunction
POSSIBLE
• Shift solenoid B malfunction
CAUSE
• Pressure control solenoid malfunction
• Body GND malfunction
• Control valve body malfunction
2. Selector lever malfunction
3. Parking mechanism not properly operation
4. Torque converter malfunction
Note
• Before following troubleshooting steps, make sure that Automatic Transale On-Board Diagnostic
and Automatic Transale Basic Inspection are conducted.
Diagnostic procedure
STEP
1 When vehicle is stopped on a flat, level road and
engine is off, does vehicle move when pushed?
(in D, S ranges or N, R positions and brake is
released)
2 Disconnect PCM.
Is resistance between ground terminal at PCM
connector and body ground less than 5.0
ohms?
3 Check LPS PID value using WDS or equivalent.
Is LPS PID value okay?
(See F–45 PCM INSPECTION.)

NO.2 VEHICLE MOVES IN N POSITION
2 Vehicle moves in N position
• Vehicle creeps in N position.
DESCRIPTION
• Vehicle creeps if brake pedal is not depressed in N position.
• 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 harnesses.
1. Clutch burned (Forward clutch)
• Control valve body malfunction
POSSIBLE
2. Selector lever position disparity (Although the selector indicator shows N position, hydraulic circuit
CAUSE
shows D range or R position)
Note
• Before following troubleshooting steps, make sure that Automatic Transale On-Board Diagnostic
and Automatic Transale Basic Inspection are conducted.
Diagnostic procedure
STEP
1 Does vehicle creep when selector lever is
moved slightly in N position?
