What is the reason for no voltage display on the Dowjoo electric vehicle dashboard?

4 Answers

Dowjoo electric vehicle dashboard showing no voltage is due to a short circuit in the dashboard wiring or connectors, causing the dashboard to malfunction and fail to display voltage properly. In such cases, immediate repair at a 4S shop is required. How electric vehicle dashboards work: Cars generally use electronic dashboards, which can be either pointer-type or liquid crystal digital display-type. The dashboard contains digital integrated circuits that calculate voltage pulses received from the ignition coil to drive pointer movement or digital display. Functions of electric vehicle dashboards: Electric vehicle dashboards typically include a speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge, among others. This shows that the main function of an electric vehicle dashboard is to allow the owner to monitor the vehicle's operating conditions in real-time.

My Daojue electric vehicle also encountered the issue of the dashboard showing no voltage last month, which really startled me. Common causes include the main battery pack being completely depleted or having too low voltage, a blown fuse causing circuit interruption, loose or poor contact at the battery terminals, or a malfunction in the dashboard sensor itself. This isn't just a display issue; it could also affect the vehicle's ability to start or driving safety. I recommend first checking if the battery connections are tight or trying to recharge and restart the vehicle system. If there's no improvement, promptly visit a professional repair shop for a thorough inspection. Regular maintenance can help reduce the likelihood of such faults and ensure worry-free long-distance travel.

When the dashboard shows no voltage, it could be due to the main battery being dead or a system error causing inaccurate readings. I had a similar experience, and it turned out to be caused by a worn charging plug. In such cases, the vehicle may not operate normally, increasing risks. It's best to pull over immediately, power off, and check for simple issues like aging wiring or blown fuses. Avoid attempting repairs yourself to prevent worsening the problem. Visiting a 4S shop for a comprehensive diagnosis will provide peace of mind and ensure smoother daily driving.

My Daojue EV once had no voltage display on the dashboard, which was caused by a false alarm from the voltage sensor. Restarting the vehicle restored normal function. If this doesn't work, it might be a battery issue, requiring a visit to the service center. During maintenance, it's advisable to check the battery status more frequently to avoid trouble.

Can the Dodge Ram Use 92 Octane Gasoline?

The Dodge Ram can use 92 octane gasoline. This octane rating is recommended in the vehicle's official owner's manual. In addition to checking the suitable gasoline octane rating in the owner's manual, the Dodge Ram also indicates it on the fuel tank cap. You can usually determine the appropriate gasoline grade based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a ratio between 10.0-11.5 should use 95 octane. If the compression ratio is even higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the required gasoline grade. High-compression engines can also be tuned to use lower-octane gasoline, as factors like ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane rating, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline octane rating in the Dodge Ram, simply switch back to the correct one after refueling. However, long-term use of the wrong octane rating can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increased octane value can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. The significantly lower octane value reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is generated during the upward stroke, making the engine run very unstable. Mild knocking only increases noise without significant engine damage, but noticeable knocking indicates severe engine conditions, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.

Is 80 points a passing score for C1 Subject 3?

80 points is not a passing score. The passing score for the C1 Subject 3 test is 90 points, with a full score of 100 points. According to Article 30 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), the passing standards for each subject test are as follows: Subject 1 test has a full score of 100 points, and a score of 90 points is considered passing. Subject 2 test has a full score of 100 points. For large buses, trailers, city buses, medium-sized buses, and large trucks, a score of 90 points is considered passing. For other vehicle types, a score of 80 points is considered passing. Subject 3 road driving skills and safe and civilized driving knowledge tests each have a full score of 100 points, and a score of 90 points is considered passing. Subject 3: Includes road driving skills test and safe and civilized driving knowledge test. It is part of the motor vehicle driving license test and is also the abbreviation for the road driving skills and safe and civilized driving knowledge test in the motor vehicle driver test. The content of the road driving skills test varies for different vehicle types. Subject 3 test items: Vehicle preparation, light simulation, starting, straight-line driving, lane changing, passing intersections, passing crosswalks, passing school zones, passing bus stops, meeting vehicles, overtaking, U-turns, gear shifting operations, left turns at intersections, right turns at intersections, and pulling over. Only straight-line driving, gear shifting, and pulling over are mandatory. The safe driving knowledge test generally includes: safe and civilized driving operation requirements, safe driving knowledge in bad weather and complex road conditions, emergency handling methods such as tire blowouts, and post-accident handling knowledge. Precautions for the C1 Subject 3 test are as follows: Pre-test preparation: Walk around the vehicle once before getting in, and pause near the monitoring area. Light simulation: Check if the light switch is reset before the simulation test begins. Starting: Observe the surrounding traffic environment before starting. During driving: Keep your eyes on the road ahead and avoid following too closely. Deduction points for the C1 license Subject 3 test are as follows: Failing to observe the rear and right traffic conditions through the interior and exterior rearview mirrors before stopping results in failure. Failing to stop within the specified distance after the examiner issues the pull-over command results in failure. If the vehicle body exceeds the right edge of the road or the sidewalk edge after stopping, it results in failure. Failing to observe the side and left traffic conditions before opening the door after stopping results in failure. Not using or incorrectly using the turn signal before stopping deducts 10 points. Turning the steering wheel less than 3 seconds after activating the turn signal before stopping deducts 10 points. If the vehicle body is more than 30 cm from the right edge of the road or the sidewalk edge after stopping, it deducts 10 points. Not tightening the parking brake lever after stopping deducts 10 points. Releasing the foot brake before tightening the parking brake lever deducts 10 points. Not turning off the engine before getting out deducts 5 points.
