NO.1 VEHICLE DOES NOT MOVE IN D RANGE, OR IN R POSITION [SJ6A-EL]


id050307800600

1
Vehicle does not move in D range, or in R position
DESCRIPTION
•  Vehicle does not move when accelerator pedal is depressed.
POSSIBLE CAUSE
•  If the vehicle does not move in D range 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 range-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 GND malfunction
•  Body GND 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
Note
•  Before following the troubleshooting steps, make sure that the Automatic Transmission On-Board Diagnostic and Automatic Transmission Basic Inspection are conducted. (See BASIC INSPECTION [SJ6A-EL].)

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 range or N, R positions with the brake pedal released)
Yes
Go to the next step.
No
Inspect for parking mechanism.
2
•  Start the engine.
•  Does vehicle move when selector lever in between N position and D range?
Yes
Inspect or adjust selector lever.
No
Go to the next step.
3
•  Stop the engine.
•  Inspect following solenoid.
―  Shift solenoid C
―  Shift solenoid D
―  Shift solenoid E
―  Shift solenoid F
―  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 malfunctioning parts.
(See Automatic Transmission Workshop Manual SJ6A-EL.)
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.
