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 AT. Since a malfunction in the sensor circuit or output circuit is the cause of the malfunction in the AT, inspect the sensors, output circuit, and the related wiring harnesses.

• Clutch burnt (C1 clutch, C4 clutch, One-way clutch)

• Line pressure low

• Shift solenoid B malfunction

• Shift solenoid C malfunction

• Shift solenoid E malfunction

• Shift solenoid G malfunction

• Control valve body malfunction

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

• TR switch mis-adjustment

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 and TR switch.

(See SELECTOR LEVER INSPECTION.)

(See TRANSMISSION RANGE (TR) SWITCH INSPECTION [SJ6A-EL].)

(See TRANSMISSION RANGE (TR) SWITCH ADJUSTMENT [SJ6A-EL].)

2

• Inspect the following solenoid:

  (See SOLENOID VALVE INSPECTION [SJ6A-EL].)

• Shift solenoid B

• Shift solenoid C

• Shift solenoid E

• Shift solenoid G

• Are these solenoids normal?

Yes

Overhaul the transmission and repair or replace any malfunctioning parts (clutch slippage, worm).

(See AUTOMATIC TRANSMISSION REMOVAL/INSTALLATION [SJ6A-EL].)

(See Automatic Transmission Workshop Manual [SJ6A-EL].)

No

Inspect the coupler component.

• If normal, replace the control valve body.

  (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].)

  (See CONTROL VALVE BODY INSTALLATION [SJ6A-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. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
