id0503k3800700

2 | Vehicle moves in N position
DESCRIPTION | • Vehicle creeps in N position. • Vehicle creeps if brake pedal is not depressed in N position.
POSSIBLE CAUSE | • If the vehicle moves in N position, basically, the malfunction is in the ATX. 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 wiring harnesses. ― Clutch burnt (C1 clutch, C3 clutch, One-way clutch) • Line pressure low • Shift solenoid C malfunction • Shift solenoid E malfunction • Line pressure control solenoid malfunction • Control valve body malfunction ― Selector lever position disparity (Although the selector indicator shows N position, the hydraulic circuit shows D or R position) • N 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 [AY6A-EL, AY6AX-EL].)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Does the vehicle creep when selector lever is moved slightly in N position? | Yes | Go to the next step.
No | Inspect and adjust the selector lever. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.) Perform N position learning. (See TCM NEUTRAL POSITION LEARNING [AY6A-EL, AY6AX-EL].)
2 | • Inspect following solenoid. ― Shift solenoid C (See SHIFT SOLENOID C INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid D (See SHIFT SOLENOID D INSPECTION [AY6A-EL, AY6AX-EL].) • Are these solenoids normal? | Yes | Replace the transaxle. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No | Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
3 | • Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If malfunction remains, inspect the related Service Bulletins and/or On-line Repair 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.
