What does the Baojun 560 engine anti-theft authentication failure mean?
3 Answers
Baojun 560 engine anti-theft authentication failure is caused by the mismatch between the remote key and the engine computer, or water ingress from the windshield film, which flows along the glass into the center console, leading to authentication failure. Below are the relevant details about Baojun 560: 1. The front design of Baojun 560 follows the family-style design of Baojun, with LED daytime running lights located below the fog lights. The headlights are equipped with LED position lights, and it features a 10-inch large touchscreen entertainment system, with the control area adopting two knobs. 2. In terms of power, Baojun 560 is equipped with a 1.8L naturally aspirated engine delivering 101kW and 186Nm, paired with a 5-speed manual transmission and AMT transmission.
Last month, my Baojun 560 also popped up this warning, which was really frustrating. It means the car's anti-theft system didn't recognize your key, and the engine was locked by the anti-theft system. The most common reason is that the key battery is dead—a small battery costing just a few yuan can be replaced by yourself. If the key has been dropped or soaked in water, the chip might be damaged. Sometimes, nearby strong magnetic field devices can also interfere with the signal, such as high-voltage power lines. Once, I couldn't start the car in a parking lot no matter what, and it turned out the spare key and the main key were strung together, causing mutual interference. Don't force it—try placing the key separately and starting again. If it still doesn't work, call the 4S store immediately.
Having repaired dozens of such cases, it boils down to a failed handshake between the car and the key. Baojun's anti-theft system requires the key chip to send signals to the body control module—authentication failure means this chain is broken. On the key side, it could be low battery or a damaged chip; on the car side, potential culprits include a faulty steering wheel lock module or loose wiring connectors. Some aftermarket GPS anti-theft devices can also cause conflicts. The troubleshooting process is straightforward: first read fault codes with a diagnostic tool, then inspect the signal receiving coil, and finally test the key's output power. Routine maintenance should include reminding technicians to check wiring harnesses near the OBD port to prevent this issue.
