What causes the Wuling Hongguang Mini's entire vehicle system failure?

[LaHolden]

Wuling Mini displays a full vehicle system failure due to a short circuit or open circuit in the power supply to ground of the ignition switch fuel injection system relay. Below is an introduction to related information about the Wuling Hongguang Mini: 1. Configuration: The Wuling Hongguang Mini's electric motor has a maximum power of 20kw and a maximum torque of 85nm. This vehicle uses lithium-ion batteries throughout the series, which are stronger and have higher energy density. The front suspension of the Wuling Hongguang Mini uses a MacPherson independent suspension, while the rear suspension uses a multi-link non-independent suspension. 2. Dimensions: The Wuling Hongguang Mini has a wheelbase of 1940mm, with length, width, and height being 2917mm, 1493mm, and 1621mm respectively. This is a 3-door, 4-seat vehicle, with a curb weight of approximately 700kg.

I've been driving the Wuling Hongguang Mini for a while and encountered a complete system failure once. The car suddenly shut down, even the lights went out. Fortunately, no accident happened. Later at the service center, they said it was caused by a software bug—the onboard computer falsely reported error codes. Common causes also include unstable battery voltage, such as an aging battery or insufficient charging, which can lead to a complete system crash; or wiring harness issues, like loose or worn-out main connections that interrupt current flow. Faulty sensors, like temperature probes or speed sensors, can also trigger system alarms. It's recommended to perform regular maintenance rather than waiting for a breakdown; update system software periodically to reduce false alarm risks. That experience taught me that electric mini cars have more electronic issues—it's best to get professional inspections every six months. Spending a little money ensures safer driving. If you encounter a failure, don't panic—immediately stop to check battery connections; if a soft reset doesn't work, go straight to the 4S store for solutions.

As someone who drives an electric vehicle daily, I find that vehicle malfunctions are often related to the core controller. The system called ECU is responsible for managing everything, and if the program malfunctions, it may report false errors, making it impossible to stop the car. Additionally, issues with high-voltage circuits, such as short circuits or poor connections, can cause a complete shutdown when the fuse blows. The battery management system may also initiate a protective shutdown if it detects abnormalities, such as over-discharge or insufficient voltage. Malfunctioning wheel speed sensors can also trigger false warnings. I often recommend using simple tools to read the fault codes and identify the source first, rather than rushing to the shop; or directly seeking authorized service for software upgrades to prevent issues. During maintenance, check the wiring harness to prevent wear and avoid long-term vibration-induced loosening. When charging, avoid overcharging to maintain battery health, which reduces overall failure frequency. Regularly cleaning connectors can also save on repair costs.

When it comes to the Wuling Hongguang Mini's vehicle system failures, common issues include battery failure or poor connections leading to current interruption. There are many software bugs, possibly due to slow system updates; sensor failures can trigger false alarms. Repair costs vary: software upgrades are free, but replacing hardware like the ECU can cost thousands. Prevention is better than repair—regular maintenance checks on the battery and fuses save money and ensure safety. If the warning light comes on, don't move the vehicle; pull over and turn on the hazard lights.
