What are the causes of instrument panel failure in the Baojun 730?

Introduction to the causes of instrument panel failure in the Baojun 730: Battery depletion: The starter begins to turn but lacks sufficient speed or power, eventually leading to the starter making noise without turning. Low temperatures in winter or forgetting to turn off certain electrical devices can prevent the vehicle from starting, especially when used for long periods of short-distance, low-speed driving in winter, causing the battery voltage to drop below the rated value and preventing normal operation. Gasoline flow obstruction: No oil pressure in the engine fuel supply line. This situation often occurs on particularly cold mornings due to long-term dirt accumulation in the fuel lines. At extremely low temperatures, water mixed with debris can block the fuel lines, resulting in failure to start. Poor ignition system performance: In cold weather, the low intake temperature causes poor fuel atomization in the cylinders. Combined with insufficient ignition energy, this can lead to cylinder flooding, where excessive fuel accumulates in the cylinders, exceeding the ignition limit concentration and preventing the engine from starting.
As a veteran driver with nearly a decade of experience, I can tell you that the most common issue with the Baojun 730 dashboard is poor power cable contact. Especially the wiring harness under the steering wheel—its connectors tend to loosen after prolonged driving on bumpy roads. If the dashboard suddenly goes black or the needles jump erratically, first try turning off the engine and restarting it to perform a self-check; sometimes it's just a temporary contact issue. If the problem persists after restarting, chances are you'll need to remove the steering wheel cover to inspect the wiring harness connectors. Here's a handy tip: after starting the engine, feel the back of the dashboard for excessive heat—if it's scalding hot, there might be a short circuit on the circuit board, which requires immediate repair. Last year, my car's temperature gauge malfunctioned due to rainwater seeping into the connector, and it was only fixed after replacing it with a moisture-proof connector.
