What Causes an Automatic Transmission to Spin Freely Without Moving When Shifted?

The reasons why an automatic transmission spins freely without moving when shifted include: 1. Insufficient transmission fluid or low internal oil pressure; 2. Incorrect gear switch signal; 3. Issues with the shift solenoid valve wiring or the solenoid valve itself; 4. Problems with the internal actuating mechanism of the transmission. Here are the solutions: 1. Check whether the transmission has insufficient fluid, whether the main oil pressure and gear oil pressure are normal, then verify if the gear switch signal is correct, if the wiring from the transmission computer to the shift solenoid valve is intact, and if the gear solenoid valve is functioning properly. 2. If all these are normal, it indicates a problem with the internal control system of the transmission, and the transmission should be disassembled to inspect the internal actuating components.

What is the reason for the beeping sound and failure to open when using the Alphard's power sliding door?

There are two main reasons why the remote key cannot unlock the door: one is an issue with the remote control or radio frequency device, and the other is a problem with the main unit or door control component. Here are some relevant tips: 1. Automatic opening: When a person approaches the automatic door from outside or inside at a normal walking speed, the door should open automatically. The movement of the door should be smooth and without any collisions. After the door opens, it should remain open while the person passes through at a normal speed. 2. Automatic closing: When a person moves out of the sensor range of the automatic door, the door should automatically close after a delay of 1-10 seconds (the duration can be set via the automatic door switch parameters). The movement of the door should be smooth and without any collisions.

What Causes the Conflict Between CarPlay Navigation and Music Audio?

There are several scenarios to analyze regarding the conflict between CarPlay navigation and music audio: 1. CarPlay navigation voice directly interrupts the music audio: This situation can be resolved by selecting a different audio mixing mode in the navigation settings. For example, when using maps, you can choose the accessibility option in the navigation settings within the settings menu and set the audio mixing mode to 'lower music volume' to prevent the music from being directly interrupted. 2. Music audio stutters during CarPlay navigation voice prompts: There are many possible reasons for this, such as insufficient phone memory, poor phone network connection, issues with the phone's data cable, problems with the car's infotainment system, or incompatibility between the navigation and music apps. The solution should be determined based on the specific cause of the problem.

How to activate truck ETC?

Truck ETC activation process: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth is on'. If 'Tag invalid' appears when inserting and removing twice without attaching the electronic tag, this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually there's a download QR code on the electronic tag), and enter the device activation interface. Click 'Device Connection' and wait patiently for the 'Connection Successful' prompt. After successful connection, upload a photo of the vehicle's front to complete activation. Truck ETC installation position: For large vehicles like trucks, ETC should be installed in the middle-lower part of the front windshield; For small vehicles like cars and vans, the ETC card and OBU device should be installed in the middle-upper part of the front windshield.

What Are the Criteria for Replacing Car Tires?

The criteria for replacing car tires include: the tire rubber aging to the critical point of deterioration, the tire being worn down to the wear indicator, bulging on the tire sidewall, deformation or bulging on the tread, the tire leaking and being irreparable, unexplained noises during driving, uneven wear, misalignment, and abnormal wear. Lifespan of Car Tires: The lifespan of car tires is generally 3-5 years or a mileage of 60,000-80,000 kilometers under normal driving conditions. However, depending on the driver's habits, road conditions, and parking environment, the lifespan of car tires may vary. Hazards of Using Expired Tires: Expired tires suffer from rubber aging, making them prone to cracking, reduced flexibility, and severely diminished heat dissipation. This not only drastically reduces comfort but also significantly impairs acceleration and braking performance. High-speed driving with expired tires carries the risk of a blowout. Therefore, expired tires must be replaced, even if the wear has not yet reached the wear indicator. Method for Replacing Tires: Park the car, turn off the engine, and engage the handbrake to prevent sliding. Loosen the bolts in a diagonal sequence. Jack up the vehicle to a certain height. Remove the bolts and take off the old tire. Install the new tire and tighten the anti-theft bolts in a diagonal sequence. Lower the vehicle and tighten the bolts and nuts. Precautions for Tire Replacement: Choose tires of the same specifications, replace the valve stem at the same time, pay attention to the installation direction and inflation, check the tire pressure, perform a four-wheel alignment after replacement, slightly loosen the fixing bolts before using the jack to partially lift the vehicle, and select tires with guaranteed quality.
