Mercedes-Benz reversing radar not working reasons include damaged reversing light switch, signal not reaching the radar main unit, wiring issues, or faulty sensors. Below are the detailed reasons why the Mercedes-Benz reversing radar may not be working: Damaged reversing light switch: This can cause the reversing radar to stop functioning (most reversing radars operate in conjunction with the reversing light switch. Engaging reverse gear activates the reversing light switch, supplying power to both the reversing lights and the reversing radar simultaneously). Reversing light signal not reaching the radar main unit: Check if the reversing lights are functioning properly and if the wiring is intact. Wiring issues: There may be a problem with the wiring between the reversing radar controller and the sensors. Faulty sensors: The reversing radar controller or the sensors themselves may be defective.

What Causes the Motor to Spin Idly?

Motor spinning idly can be attributed to the following reasons: 1. Severe wear of the starter carbon brushes: The symptom during startup is weak starting power, and the crankshaft can be clearly seen turning very slowly through the belt and pulley. When the wear is extremely severe, the starter cannot drive the crankshaft to rotate at all, only producing an electric current sound. 2. Damage to the starter clutch: Normally, the starter operates at a speed of 120r/min, while the engine idles at around 900r/min after starting. The function of the clutch is to prevent the engine from driving the starter in reverse after startup, which could happen if the driver fails to release the key in time, causing the small flywheel gear and large flywheel gear to remain engaged, leading to the starter burning out.

Where is the towing point at the rear of the Baojun 360?

Owners can also identify hidden spaces by inspecting the front and rear bumpers - the circular or square cover indicates the towing hook location. Towing vehicle starting method: Start the towing vehicle in 1st gear to ensure sufficient torque for towing power, while maintaining controlled speed for smooth operation. Increase power output when slight resistance is felt. For manual transmission models, avoid sudden clutch release; use semi-engagement for gradual starting to prevent vehicle damage.
