NO.2 VEHICLE MOVES IN N POSITION [AW6A-EL, AW6AX-EL]SM2445395

id050310800700

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

• Coupler component malfunction

• Control valve body malfunction

― Selector lever position disparity (Although the selector indicator shows N position, the hydraulic circuit shows D range or R position)

• Neutral 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 [AW6A-EL, AW6AX-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.
1		No	Inspect and adjust the selector lever. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.) Perform neutral position learning. (See NEUTRAL POSITION LEARNING [AW6A-EL, AW6AX-EL].)
2	• Inspect following solenoids. (See SOLENOID VALVE INSPECTION [AW6A-EL, AW6AX-EL].) ― Shift solenoid C ― Shift solenoid E ― Line pressure control solenoid • Are these solenoids normal?	Yes	Overhaul the transaxle and repair or replace any malfunctioning parts. (See Automatic Transaxle and Transfer Workshop Manual AW6A-EL AW6AX-EL.)
2		No	Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
3	• Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If malfunction remains, inspect the related Service 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.
