Vehicle does not move in D, M or R position
DESCRIPTION
•  Vehicle does not move when accelerator pedal is depressed.
POSSIBLE CAUSE
•  If the vehicle does not move in D, M or R position, basically, the malfunction is in the AT. (Vehicle will move even with a malfunction in the TCM.) Since a malfunction is in the sensor circuit or output circuit is the cause of the malfunction in the AT, inspect the sensors, output circuit, and the related wiring harnesses.
―  Clutch slippage, worn (D position-C1 clutch, One-way clutch, R position-C3 clutch, B4 brake, One-way clutch)
•  Line pressure low
•  Shift solenoid A malfunction
•  Shift solenoid B malfunction
•  Shift solenoid C malfunction
•  Shift solenoid E malfunction
•  Line pressure control solenoid malfunction
•  Shift solenoid G malfunction
•  Sensor ground malfunction
•  Body ground malfunction
•  Control valve body malfunction
―  Selector lever malfunction
―  Parking mechanism not operating properly
―  Torque converter malfunction
―  TCM malfunction
―  Foreign materials or water mixed in ATF
―  Improper ATF amount

Diagnostic procedure

STEP

INSPECTION

ACTION

1
•  When the vehicle is stopped on a flat, level road and the engine off, does the vehicle move when pushed (in D, M, N, or R positions with the brake pedal released)?
Yes
Go to the next step.
No
Inspect for the parking mechanism.
2
•  Start the engine.
•  Does the vehicle move when selector lever in between N and D position?
Yes
Inspect the selector lever.
No
Go to the next step.
3
•  Stop the engine.
•  Inspect the following solenoid:
―  Shift solenoid A
―  Shift solenoid B
―  Shift solenoid C
―  Shift solenoid E
―  Shift solenoid G
―  Line pressure control solenoid
•  Are these normal?
Yes
Overhaul the transmission and repair or replace any malfunctioning parts (clutch slippage, worn).
(See Automatic Transmission Workshop Manual [SJ6A-EL].)
No
Inspect the coupler component.
•  If normal, replace the control valve body.
4
•  Verify test results.
―  If normal, return to the diagnostic index to service any additional symptoms.
―  If malfunction remains, inspect the related Service Information and perform repair or diagnosis.
•  If the vehicle is repaired, troubleshooting completed.
•  If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
