Why can't the Chery Tiggo 5 automatic transmission engage?

[DeJasper]

The gear may be locked or not fully braked when parking, directly shifting into P gear, causing gear braking instead of brake braking. Precautions for shifting gears in automatic transmission vehicles: Generally, after parking an automatic transmission vehicle, it should be shifted to P gear to prevent rolling away in neutral or being unable to remove the key when in drive gear. To continue driving, the engine must be started and the brake pedal must be pressed to shift gears. When the brake pedal is pressed, the brake light switch will activate, sending a signal to the computer, allowing the gear to be engaged. If the brake light switch malfunctions, it will not send a signal to the computer, making it impossible to shift gears. In this case, it is necessary to visit a repair shop to check the brake light switch. Automatic Transmission: It does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. Generally, automatic transmission vehicles have six gear positions, from top to bottom: P, R, N, D, S, L.
