NO.5 NO CREEP AT ALL [AW6A-EL, AW6AX-EL]

NO.5 NO CREEP AT ALL [AW6A-EL, AW6AX-EL]SM2445398

id050310801000

No creep at all

DESCRIPTION

• Vehicle does not move in D range and R position when idling on a flat paved road.

POSSIBLE CAUSE

• Either engine output low or there is clutch slippage.

― Clutch burnt (C1 clutch, C3 clutch)

• Line pressure low

• Shift solenoid C malfunction

• Shift solenoid D malfunction

• Shift solenoid E malfunction

• Line pressure control solenoid malfunction

• Shift solenoid F malfunction

• Body GND malfunction

• Coupler component malfunction

• Control valve body malfunction

― Transaxle fixed in 3GR or 5GR* (Operation of fail-safe function)

• Short or open circuit in wiring harness

• Poor connection of connector

• Malfunction of electronic parts of output and input system

― There is no engine torque

• Torque converter malfunction

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 in P and/or N position?	Yes	Inspect or adjust the selector lever. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.)
1	• Does the vehicle creep in P and/or N position?	No	Go to the next step.
2	• Stop the engine. • Inspect following solenoids. (See SOLENOID VALVE INSPECTION [AW6A-EL, AW6AX-EL].) ― Shift solenoid C ― Shift solenoid D ― Shift solenoid E ― Shift solenoid F ― Line pressure control solenoid • Are these solenoids normal?	Yes	Go to the next step.
2		No	Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
3	• Perform the stall test. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].) • Is the stall speed below specified value?	Yes	Inspect the ATF condition. • If large amount of metal specks are found, overhaul the transaxle and repair or replace any malfunctioning parts. (See Automatic Transaxle and Transfer Workshop Manual AW6A-EL AW6AX-EL.) • If a large amount of metal specks are not found, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
3		No	Replace the torque converter. (See TORQUE CONVERTER REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
4	• 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.
