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.
- Clutch slippage, burnt (C1 clutch, C2 clutch, C3 clutch, B1 brake)
- Line pressure low
- Incorrect accelerator opening signal
- VSS malfunction
- Input/turbine speed sensor malfunction
- Sensor ground malfunction
- Shift solenoid C malfunction

- Line pressure control solenoid malfunction
- TCC control solenoid malfunction
- Shift solenoid F malfunction
- Body ground malfunction
- Control valve body malfunction
- Wheel speed signal malfunction
