What Causes the Electronic Steering Lock Failure in Baojun Vehicles?
4 Answers
Here are the specific reasons for the electronic steering lock failure in Baojun vehicles: 1. Internal Dirt Accumulation: Electronic steering lock failure often occurs due to excessive internal dirt, clogged filters, or low oil levels in the oil reservoir. Additionally, a significant amount of air in the power steering system can also lead to electronic steering lock failure. 2. Presence of Foreign Objects: Foreign objects in the steering system causing the steering pump flow control valve to stick, insufficient tire pressure, interference or loose connections in the steering column, loose or slipping pump belts, or a loosely installed pump can all result in electronic steering lock failure. 3. Loose Bolts: Loose bolts at oil pipe connections leading to steering fluid leakage, excessive wear of the steering piston cylinder, poor sealing of oil seals, or stuck and damaged control valves are also causes of this failure.
I've been driving for nearly 20 years and have encountered electronic steering lock failures several times, mainly in Baojun vehicles, often due to sensor malfunctions or wiring short circuits. For example, during rainy and humid weather, sensor connectors are prone to oxidation and poor contact, leading to lock-ups. Sometimes the key chip isn't detected, causing the system to misjudge and lock. Low battery voltage can also trigger the protection mode. Just last month, my neighbor's Baojun 730 was stranded on the roadside because of this and had to be towed for repairs. When dealing with it, don't force the steering wheel, as it can easily damage the power steering pump. It's advisable to regularly check the steering system, especially cleaning the sensor area to prevent dust buildup. Safe driving always comes first. If you notice any abnormal sounds or steering wheel stiffness, seek professional diagnosis immediately to avoid worsening the problem by tampering yourself.
As someone who frequently repairs cars, I believe that the electronic steering lock failures in Baojun vehicles are mostly caused by ECU control unit malfunctions or wiring harness issues. The electronic steering lock is controlled by a computer, and internal short circuits due to module aging or impact can easily cause errors. Wiring harness wear or damage from rodents can also lead to short circuits. Another factor is mismatched key systems, especially if the keys were replaced but not properly synchronized. This issue is most commonly seen in the Baojun 510. It's recommended to first check the battery voltage, which should be around 12.6 volts. If the voltage is low, try charging it. If that doesn't work, a diagnostic scanner should be used to read the fault codes. When driving, avoid rough roads to minimize vibration damage. Repairs for this issue can be costly, so prevention is key to saving money. Safety comes first—never ignore any warning lights.
As a Baojun owner, the steering lock malfunction is really annoying. The reasons are quite simple, commonly due to dirty sensors or loose connectors, often caused by water ingress during regular car washes leading to short circuits. Another frequent issue is a dead key fob battery, which fails to be detected and triggers the lock. Battery problems are also not uncommon, as falling below the threshold activates the protection mechanism. Dealing with it is quite urgent—last time, while driving, my steering wheel suddenly locked, scaring me into pulling over immediately with hazard lights on. Restarting the vehicle sometimes helps, but a visit to the 4S shop for an ECU check is necessary. Maintenance tips include regularly cleaning the connectors under the steering wheel and replacing the battery every six months. Safety is paramount, and delays are not an option.
