NO.1 VEHICLE DOES NOT MOVE IN D OR IN R POSITION [AY6A-EL, AY6AX-EL]

id0503k3333600

1 | Vehicle does not move in D or in R position
DESCRIPTION | • Vehicle does not move when accelerator pedal is depressed.
POSSIBLE CAUSE | • If the vehicle does not move in D or R position, basically, the malfunction is in the ATX. (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 ATX, inspect the sensors, output circuit, and the related wiring harnesses. ― Clutch slippage, worn (D position-C1 clutch, One-way clutch, R position-C3 clutch, B2 brake) • 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 F malfunction • Sensor ground malfunction • Body ground malfunction • Control valve body malfunction ― Selector lever malfunction ― Parking mechanism not operating properly ― Torque converter malfunction ― Coupler component malfunction ― N position learning is not performed Note • Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION [AY6A-EL, AY6AX-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 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 position? | Yes | Inspect or adjust selector lever. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.) Perform N position learning. (See TCM NEUTRAL POSITION LEARNING [AY6A-EL, AY6AX-EL].)
No | Go to the next step.
3 | • Stop the engine. • Inspect following solenoid. ― Shift solenoid A (See SHIFT SOLENOID A INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid B (See SHIFT SOLENOID B INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid C (See SHIFT SOLENOID C INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid E (See SHIFT SOLENOID E INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid F (See SHIFT SOLENOID F INSPECTION [AY6A-EL, AY6AX-EL].) ― Line pressure control solenoid (See LINE PRESSURE CONTROL SOLENOID INSPECTION [AY6A-EL, AY6AX-EL].) • Are these normal? | Yes | Go to the next step.
No | Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
4 | • Perform the stall test. (See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].) • Is the stall speed within the specified? | Yes | Replace the transaxle. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No | Replace the torque converter. (See TORQUE CONVERTER REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
5 | • Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If malfunction remains, inspect the related Service Bulletins and/or On-line Repair 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.
