NO.5 NO CREEP AT ALL [AY6A-EL, AY6AX-EL]

id0503k3801000

5 | No creep at all
DESCRIPTION | • Vehicle does not move in D 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 ground 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 [AY6A-EL, AY6AX-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.)
No | Go to the next step.
2 | • Stop the engine. • 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] ― Shift solenoid E (See SHIFT SOLENOID E INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid F (See SHIFT SOLENOID F INSPECTION [AY6A-EL, AY6AX-EL].) ― Line pressure control solenoid (See LINE PRESSURE CONTROL SOLENOID INSPECTION [AY6A-EL, AY6AX-EL].) • Are these solenoids normal? | Yes | Go to the next step.
No | Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
3 | • Perform the stall test. (See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].) • Is the stall speed within the specified? | Yes | Inspect the ATF condition. If large amount of metal specks are found, replace the transaxle. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].) If a large amount of metal specks are not found, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No | Replace the torque converter. (See TORQUE CONVERTER REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
4 | • 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.
