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 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 range-C1 clutch, One-way clutch, R position-C3 clutch, B2 brake)

•  Line pressure low

•  Shift solenoid C malfunction

•  Shift solenoid D 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

―  Neutral 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 [AW6A-EL, AW6AX-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.
1		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. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.) Perform neutral position learning. (See NEUTRAL POSITION LEARNING [AW6A-EL, AW6AX-EL].)
2		No	Go to the next step.
3	• Stop the engine. • Inspect following solenoid. (See SOLENOID VALVE INSPECTION [AW6A-EL, AW6AX-EL].) ― Shift solenoid C ― Shift solenoid D ― Shift solenoid E ― Shift solenoid F ― Line pressure control solenoid • Are these normal?	Yes	Go to the next step.
3		No	Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
4	• Perform the stall test. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].) • Is the stall speed below specified value?	Yes	Overhaul the transaxle and repair or replace any malfunctioning parts. (clutch slippage, worn) (See Automatic Transaxle and Transfer Workshop Manual AW6A-EL AW6AX-EL.)
4		No	Replace the torque converter. (See TORQUE CONVERTER REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
5	• Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If the 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.
