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

id0503a1815000

1 | Vehicle does not move in D, S, L ranges, or in R position
DESCRIPTION | • Vehicle does not move when AP 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 in the sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the related harnesses. 1. Clutch slipped, 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. Parking mechanism not properly operating 4. Torque converter malfunction 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 | • When vehicle is stopped on a flat, level road and engine is off, does vehicle move when pushed? (in D, S ranges or N, R positions and brake is released) | Yes | Go to next step.
No | Check for parking mechanism. (See ATX workshop manual (FN4A-EL) [1623-10-98E].)
2 | • Disconnect PCM. • Is resistance between ground terminal at PCM connector and body ground less than 5.0 ohms? | Yes | Go to next step.
No | Repair open ground circuit.
3 | • Check LPS PID value using WDS or equivalent. (See PCM INSPECTION [WITHOUT WU-TWC].) (See PCM INSPECTION [WITH WU-TWC].) • Is LPS PID value normal? | Yes | Overhaul control valve body and repair or replace any defective parts. (See ATX workshop manual (FN4A-EL) [1623-10-98E].) If problem remains, overhaul transaxle and repair or replace any defective parts. (See ATX workshop manual (FN4A-EL) [1623-10-98E].)
No | Repair or replace any defective parts.
4 | • Verify test results. - If normal, return to diagnostic index to service any additional symptoms. - If malfunction remains, inspect related Service Information and perform repair or diagnosis. • If vehicle repaired, troubleshooting completed. • If vehicle not repaired or additional diagnostic information not available, replace PCM.
