OBD detection in cars refers to the "On-Board Diagnostics" system, where OBD stands for On-Board Diagnostics. The OBD system primarily monitors the operating status of the engine and the exhaust treatment system in real-time. Once there is a fault or abnormal data in the engine or exhaust treatment system, the OBD system will store the fault code and illuminate the fault indicator light. Here are some details about using OBD: 1. Connect the OBD interface to the car's interface. 2. After aligning the interfaces, start the car engine and turn on the OBD switch. 3. At this point, OBD will automatically monitor all parameters of the car. You need to download the OBD app from the APP Store or application market.

What causes shaking when idling in first gear?

Here are the specific reasons for shaking when idling in first gear: 1. Driving habits: Shaking during first gear starts is likely caused by the driver's habits. 2. Excessive wear of the clutch pressure plate: Manual transmissions primarily transmit power through the clutch, and the clutch pressure plate is mainly responsible for transferring kinetic energy. The clutch pressure plate has a lifespan, and prolonged semi-engagement or the engine operating under excessive load can accelerate wear. When the pressure plate wears to a certain extent, power engagement becomes less smooth, causing the car to shake and the engine speed to become unstable. 3. Wear of the flywheel and clutch disc: Irregular wear of the flywheel and clutch disc, key components of the clutch, can lead to misalignment. During engagement, the clutch disc cannot smoothly engage.

However, in the first quarter of 2013, Tesla finally turned a profit, largely due to the launch of the Model S on June 22, 2012. It is expected that the Model S will not be domestically produced in the short to medium term. Tesla's current focus at its domestic factory is on increasing production volume. Therefore, introducing the Model S, a niche model, for domestic production would impact the capacity and supply chain localization of other mass-produced models.
