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 A
- Shift solenoid B
- Shift solenoid C
- Shift solenoid D
- Shift solenoid E
- Shift solenoid G
- Line pressure control solenoid
• Are these normal?
Yes
Replace the AT (clutch slippage, worn)
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.
