What causes the power steering failure in Baojun 730?
2 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.
