Vehicle does not move in D range, or in R position

DESCRIPTION

• Vehicle does not move when accelerator pedal depressed.

POSSIBLE CAUSE

• If vehicle does not move in D range or R position, basically, malfunction is in ATX. (Vehicle will move even with a malfunction in TCM.) Since a malfunction in sensor circuit or output circuit is cause of malfunction in ATX, inspect sensors, output circuit, and related harnesses.
- Clutch slipped, worn (D range-Low clutch, Low one-way clutch, Reduction one-way clutch, R position-Reverse clutch, Low and reverse brake, Reduction brake)
• Line pressure low
• Malfunction of shift solenoid A, B, or C
• Malfunction of sensor ground
• Malfunction of body ground
• Malfunction of control valve body
- Malfunction of selector lever
- Parking mechanism not properly operated
- Malfunction of torque converter
Note
• Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

Diagnostic procedure

STEP

INSPECTION

ACTION

1
• With vehicle stopped on a flat, paved road and engine off, does vehicle move when pushed? (in D ranges or N, R positions and brake released)
Yes
Go to next step.
No
Inspect for parking mechanism.
(See ATX Workshop Manual.)
2
• Start engine.
• Does vehicle move when selector lever in between N position and D range?
Yes
Inspect or adjust selector lever.
No
Go to next step.
3
• Stop engine.
• Inspect pressure control solenoid circuit.
• Is it okay?
Yes
• Overhaul control valve body and repair or replace any defective parts.
(See ATX Workshop Manual.)
- If problem remains, replace or overhaul transaxle and repair or replace any defective parts.
(See AUTOMATIC TRANSAXLE AND TRANSFER REMOVAL/INSTALLATION [JA5AX-EL].)
(See ATX workshop Manual.)
No
• Inspect for pressure control solenoid mechanical stuck.
- If pressure control solenoid okay, inspect for open or short circuit between TCM connector terminal 2Y and pressure control solenoid connector terminal D.
4
• Verify test results.
- If okay, return to diagnostic index to service any additional symptoms.
- If malfunction remains, inspect related Service Informations and perform repair or diagnosis.
• If vehicle repaired, troubleshooting completed.
• If vehicle not repaired or additional diagnostic information not available, replace TCM.
