No shifting
DESCRIPTION
• Single shift range only.
• Sometimes it shifts correctly.
POSSIBLE CAUSE
• When the gear position is fixed in 3GR or 5GR* due to the fail-safe operation, malfunction is in the ATX.
• Perform malfunction diagnosis according to No.6 “LOW MAXIMUM SPEED AND POOR ACCELERATION”. (See NO.6 LOW MAXIMUM SPEED AND POOR ACCELERATION [AW6A-EL, AW6AX-EL].)
― Clutch burnt (C1 clutch, C2 clutch, C3 clutch, B1 brake)
• Line pressure low
• Incorrect accelerator opening signal
• VSS malfunction
• Input/turbine speed sensor malfunction
• Sensor GND malfunction
• Shift solenoid C malfunction
• Shift solenoid D malfunction
• Shift solenoid E malfunction
• Line pressure control solenoid malfunction
• Shift solenoid F malfunction
• Coupler component malfunction
• Control valve body malfunction
― 3GR or 5GR* is fixed (Operation in fail-safe function)
• Short or open circuit in wiring harness
• Poor connection of connector
• Poor ground of shift solenoid
• Malfunction of electronic parts of output and input system
Note
• If a tire of a different diameter from the standard tire is installed, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.
