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 range 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 [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.
No
Inspect and adjust the selector lever.
Perform N position learning.
2
•  Inspect following solenoid.
―  Shift solenoid C
―  Shift solenoid D
•  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.)
No
Inspect the coupler component.
If normal, replace the control valve body.
3
•  Verify test results.
―  If normal, return to the diagnostic index to service any additional symptoms.
―  If the 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.
