What does ECM mean in a car?

ECM in a car stands for Engine Control Module, which has the function of continuously monitoring and controlling the normal operation of the engine. In modern engine management systems, the ECM is its core control component. It can provide the engine with the optimal air-fuel mixture ratio and the best ignition timing according to different engine conditions, ensuring that the engine always operates in the optimal state, and the engine's performance (power, economy, emissions) reaches its best. The automotive engine control module is one of the important automotive electronics. Early ECMs required three printed circuit boards, consisting of 12 LSIs and dozens of SSIs. Today, ECMs based on microcontrollers have been realized, requiring only one printed circuit board.

What does it mean when the dashboard shows a red battery icon?

The dashboard showing a red battery icon indicates that the car battery is not being charged. Normally, after ignition, the vehicle performs a self-check where all dashboard icons light up, and they automatically turn off if no issues are detected. Once the engine starts, the alternator charges the battery, and the warning light should go off. If the battery icon remains lit, it means the battery is not receiving charge. Possible reasons for the battery not charging include: 1. Issues with the charging system or wiring; 2. A faulty alternator that cannot generate electricity; 3. The battery itself may be defective. This situation requires prompt attention, as a depleted battery can cause the engine to stall and prevent the vehicle from starting. It's advisable to first check the battery condition and the alternator's output. If those are normal, then inspect the wiring for any shorts or disconnections.

Does touching the line with the mirror during the reverse parking in Subject 2 result in failure?

Touching the line with the mirror (rearview mirror) during the reverse parking in Subject 2 does not result in failure, as long as the body or wheels of the vehicle do not touch the line. According to the "Motor Vehicle Driver Training and Examination Syllabus," as long as the vehicle body does not exceed the ground markings during reverse parking, no points will be deducted. The rearview mirror is protruding, so whether it is considered part of the vehicle body depends on how the local examination centers identify the rearview mirror. Point deductions for reverse parking include: not following the designated route or sequence (100 points deducted), the vehicle body crossing the line (100 points deducted), failing to complete the parking (100 points deducted), and stopping midway (100 points deducted). The rules for the Subject 2 driving test state that if the vehicle stops midway, rolls back, or does not follow the voice prompts during the test, it will result in failure. Additionally, if the wheels or body of the vehicle touch the line, the test will also be considered a failure. Many learners encounter issues with touching the line during Subject 2 training, and "touching the line" is the most common reason for failing. The main cause of wheels touching the line is learners not mastering the correct timing for steering. Apart from missing the right moment to steer, another reason could be the steering speed not matching the vehicle's speed. Subject 2 point deduction standards: Not wearing a seatbelt: 100 points deducted. Starting the engine without the gear in neutral: 100 points deducted. Not using turn signals (including when starting, changing lanes, overtaking, turning, or parking by the roadside); using turn signals for less than three seconds (this is easily overlooked!); forgetting to turn off the turn signal or using it incorrectly: 10 points deducted. Stalling once: 10 points deducted. Reverse parking: Not following the designated route or sequence: 100 points deducted. Vehicle body crossing the line: 100 points deducted. Failing to complete the parking: 100 points deducted. Before reversing, if the two front wheels do not pass the control line: 100 points deducted. Exceeding the 210-second time limit: 100 points deducted. Stopping for more than 2 seconds midway: 5 points deducted each time. Hill start and stop: After stopping, if the front bumper of the vehicle is not aligned with the pole line and exceeds 50 cm forward or backward: 100 points deducted. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: 10 points deducted. After stopping, if the start time exceeds 30 seconds: 100 points deducted. Wheels touching the road edge line while driving: 100 points deducted. Rolling back more than 30 cm when starting: 100 points deducted. After stopping, if the vehicle body is more than 50 cm from the road edge line: 100 points deducted. Not pulling the parking brake tightly after stopping: 10 points deducted each time. After stopping, if the vehicle body is between 30 cm and 50 cm from the road edge line: 10 points deducted each time. Rolling back between 10 cm and 30 cm when starting: 5 points deducted each time. Parallel parking: After parking, if the vehicle body crosses the line: 100 points deducted. Not using or incorrectly using turn signals when parking: 10 points deducted. Exceeding the 90-second time limit: 100 points deducted. Touching the parking space boundary line while driving: 10 points deducted each time. Wheels touching the lane boundary line while driving: 10 points deducted each time. Stopping for more than 2 seconds midway: 5 points deducted each time. 90-degree turn: Wheels touching the road edge line: 100 points deducted. Not using or incorrectly using turn signals during the turn, or not turning off the turn signal after the turn: 10 points deducted. Stopping for more than 2 seconds midway: 5 points deducted each time. Curve driving: Wheels touching the road edge line: 100 points deducted. Stopping for more than 2 seconds midway: 100 points deducted. Not driving in second gear or higher: 5 points deducted.

What are the causes of abnormal noise when starting a car?

Reasons for abnormal noise when starting a car: 1. Engine temperature is too low: During cold starts, the engine temperature is too low to function properly; 2. Thermal expansion of the car's three-way catalytic converter: If there is abnormal noise when the car is first started, but it disappears after a while, this is caused by thermal expansion of the three-way catalytic converter and is a normal phenomenon; 3. Transmission failure: One of the reasons for abnormal noise when starting a car is a transmission failure, which causes internal gears to rub and produce noise; 4. Wear of the engine belt or chain: If the engine belt or chain is worn, it can also cause friction or abnormal noise due to idling when starting the vehicle.

How to Determine if the Throttle Body Needs Cleaning?

To determine if the throttle body needs cleaning, check whether the car accelerates stably. For any fuel-injected vehicle, when the engine is under no load, shift to neutral and press the accelerator pedal to raise the RPM to 3000, then suddenly release the pedal. Observe where the tachometer needle falls to make the judgment. Notes on throttle body cleaning: 1. If the needle quickly drops to 1000-1200 RPM, pauses slightly, then drops to 800 RPM where the idle stabilizes, the throttle body is completely normal; 2. If the needle drops directly to 800 RPM, the throttle body is slightly dirty but still basically normal and may not need immediate cleaning; 3. If the needle drops below 700 RPM and then slowly rises back to 800 RPM with unstable idle, the throttle body is severely dirty and requires immediate cleaning.
