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

id050307808500

1 | Vehicle does not move in D, M ranges, or in R position
DESCRIPTION | • Vehicle does not move when accelerator pedal is depressed.
POSSIBLE CAUSE | • If the vehicle does not move in D, M ranges 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, M ranges or N, 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 position and D range? | Yes | Inspect the selector lever. (See SELECTOR LEVER INSPECTION.)
No | Go to the next step.
3 | • Stop the engine. • Inspect the following solenoid: (See SOLENOID VALVE INSPECTION [SJ6A-EL].) ― 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 REMOVAL/INSTALLATION [SJ6A-EL].) (See Automatic Transmission Workshop Manual [SJ6A-EL].)
No | Inspect the coupler component. • If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].) (See CONTROL VALVE BODY INSTALLATION [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. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
