NO.1 VEHICLE DOES NOT MOVE IN D, S, L RANGES, OR IN R POSITION [FN4A-EL]

BME050301030205

1 | Vehicle does not move in D, S, L ranges, or in R position
DESCRIPTION | • Vehicle does not move when the acceleration pedal is depressed.
POSSIBLE CAUSE | • If the 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 PCM.) 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.

  1. Clutch slippage, worn (D, S, L ranges-Forward clutch, R position-Reverse clutch, Low and reverse brake)

  • Line pressure low
  • Shift solenoid D malfunction
  • Shift solenoid E malfunction
  • Shift solenoid A malfunction
  • Shift solenoid B malfunction
  • Pressure control solenoid 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 | When the 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 is released) | Yes | Go to the next step.
No | Inspect for parking mechanism. (See ATX workshop manual (FN4A-EL).)
2 | Disconnect the PCM connector. Is the resistance between the ground terminal at the PCM connector and the body ground less than 5.0 ohms? | Yes | Go to the next step.
No | Repair open ground circuit.
3 | Inspect the LPS PID value using the WDS or equivalent. Is the LPS PID value normal? (See PCM INSPECTION [L3].) | Yes | Overhaul the control valve body and repair or replace any malfunctioning parts. (See ATX workshop manual (FN4A-EL).) If any problem remains, overhaul the transaxle and repair or replace any malfunctioning parts. (See ATX workshop manual (FN4A-EL).)
No | Repair or replace any malfunctioning parts.
