What causes the power steering failure in Baojun 730?
3 Answers
Baojun 730 power steering failure may be caused by a damaged steering sensor. Here are the specific reasons: Solutions for damaged steering sensor: It is recommended to promptly visit a 4S shop to check for any fault codes. If fault codes are present, it is mostly caused by a failure in the power steering module. If no fault codes are found, then the steering universal joint and steering gear need to be inspected. Working principle of power steering: The booster works on a physical principle to concentrate the force distributed across the entire steering wheel more on one position, making the operation very effortless. Especially during parking, one hand can complete the steering operation very quickly.
I've been driving the Baojun 730 for a while now, and last month the power steering suddenly failed. When turning, the steering wheel became extremely heavy, like moving cement. My first reaction was to drive to a safe place and stop to avoid an accident. Later, I had a mechanic check it out, and it turned out to be caused by low battery voltage. Since the power steering system relies on an electric motor to operate, insufficient battery power and unstable voltage caused the motor to stop working. Another possibility is a faulty power steering pump or controller, or poor contact due to aging wiring. The Baojun 730 uses an electric power steering system, which is quite common for this issue. It's recommended to first check if the corresponding fuse in the fuse box for the steering has blown, and use a multimeter to test the voltage. If you don't have the tools, just take it directly to a 4S shop for repair. In my case, replacing the fuse fixed the problem, but if not addressed in time, it could be very dangerous if it fails on the highway. If you encounter this issue while driving, don't push your luck—safety first.
Last year, my Baojun 730 experienced power steering issues, making a creaking sound when turning the wheel, which required significant effort. Initially, I thought it was just because it was a new car, but after taking it to a repair shop, it was diagnosed as a faulty power steering motor. After the repair, I reflected that frequent driving through waterlogged areas might have led to moisture intrusion. Similar models like the Wuling Hongguang often encounter such faults due to various reasons: sensor data errors, short circuits in the controller wiring, or insufficient lubrication of the steering column. The Baojun 730's power steering system is particularly susceptible to battery aging, especially in winter when voltage drops quickly. The solution starts with simple checks like inspecting the fuse—if it's intact, check for loose connectors. If unsure, avoid disassembling it yourself; spending some money at a professional shop is both efficient and safe, as steering failure affects control and cannot be taken lightly for even a second.
