How to Avoid Burning the ABS Pump When Jump-Starting a French Car?

To avoid burning the ABS pump when jump-starting a French car, follow these steps: 1. Before jump-starting, turn on the vehicle's engine, remove the key, close all doors, and wait for 10 minutes; 2. During the jump-start process, after removing the negative terminal of the battery, take out the old battery. When installing the new battery, connect the positive terminal first, then the negative terminal; 3. After connecting and installing, wait for about 10 minutes, then turn on the car key, wait for 1 minute before starting the engine. This method helps prevent damage to the ABS pump. The working principle of the ABS pump is: relying on highly sensitive wheel speed sensors installed on each wheel and the vehicle's speed sensor, controlled by a computer. During emergency braking, if a wheel locks up, the computer immediately instructs the pressure regulator to release pressure from that wheel's brake caliper, allowing the wheel to resume rotation.
Last year when I was driving my Citroën, the battery died and I had a friend help jump-start it, but then the ABS light came on. It turned out that the voltage fluctuations during the jump-start damaged the pump. The repair cost over a thousand yuan, and since then I've been extra careful. Before jump-starting, I always turn off all electrical devices, including the radio and lights. The connection sequence is crucial: first attach the positive clamp to the helper car's battery, then to the dead car's positive terminal. Next, connect the negative clamp to a clean metal point on the helper car's engine block—never directly to the battery's negative terminal, as that can send a voltage surge to the ABS pump. French cars have sensitive electronics, and their manuals emphasize proper grounding techniques. I now regularly check battery condition and replace aging batteries to avoid frequent jump-starts. Winter cold makes problems more likely, so preventive maintenance saves headaches.
