Vehicle does not move in D, S, L ranges, or in R position

DESCRIPTION

• Vehicle does not move when accelerator pedal is depressed.

POSSIBLE CAUSE

• If vehicle does not move in D, S, L ranges 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 malfunction in the ATX, inspect the sensors, output circuit, and the related wiring harnesses.
1. Clutch slippage, worn (D, S, L ranges-Low clutch, Low one-way clutch, Reduction one-way clutch, R position-Reverse clutch, Low and reverse brake, Reduction brake)
• Line pressure low
• Shift solenoid A, B, or C malfunction
• Sensor GND malfunction
• Body GND malfunction
• Control valve body malfunction
2. Selector lever malfunction
3. Improper operation of parking mechanism
4. Torque converter malfunction
Note
• Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

Diagnostic procedure

STEP

INSPECTION

ACTION

1
With vehicle is stopped on a flat, level road and the engine is off, does the vehicle move when pushed? (in D, S ranges or N, R positions with the brake pedal released)
Yes
Go to the next step.
No
Inspect for parking mechanism.
(See ATX Workshop Manual.)
2
Start the engine.
Does vehicle move when the selector lever in between N position and D range?
Yes
Inspect or adjust the selector lever.
No
Go to the next step.
3
Stop the engine.
Inspect the pressure control solenoid circuit.
Is it normal?
Yes
Overhaul the control valve body and repair or replace any malfunctioning parts.
(See ATX Workshop Manual.)
If any problem remains, replace or overhaul the transaxle and repair or replace any malfunctioning parts.
(See ATX Workshop Manual.)
No
Inspect for stuck pressure control solenoid.
If pressure control solenoid is normal, inspect for open or short circuit between TCM terminal 2Y and pressure control solenoid terminal D.
4
• Verify the test results.
- If normal, return to the diagnostic index to service any additional symptoms.
- If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis.
• If the vehicle is repaired, troubleshooting is completed.
• If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
