Where is the inertia switch located on the MG6?
2 Answers
The inertia switch of the MG6 is located in the engine compartment. Introduction to the inertia switch: The inertia switch, also known as a threshold accelerometer, has wide potential applications in vibration and impact detection, inertial sensing, smart collision alarms in IoT fields, as well as in artillery launch systems and aerospace technology due to its passive and low-power characteristics. Working principle of the inertia switch: In the event of a severe collision, the steel ball overcomes the magnetic force of the magnet, rolls onto a conical track, and hits the target plate. This action opens the electrical contacts of the switch and cuts off the power supply to the fuel pump. After the fuel pump loses power, the engine will stop running within seconds. To restart the engine, the inertia switch must be manually reset.
I'm quite familiar with locating the inertia switch on the MG6 – it's something I frequently encounter during repairs. It's usually hidden in the trunk; lift the floor panel and check the inner side of the left wheel arch. You'll find a small square box with a red button or orange label. This switch is ingeniously designed to automatically pop up and cut off the fuel supply in case of a severe collision, preventing fuel leakage and potential fires. Last time, a car owner couldn't start their vehicle after a rear-end collision, and it turned out the inertia switch had tripped. To reset it, first turn off the engine, then press and hold the button until you hear a click to confirm it's reset. Afterward, remember to check the fuel lines for any leaks, and for vehicles involved in collisions, it's also essential to inspect the airbag system. Avoid unplugging connectors randomly, as incorrect wiring could blow a fuse.
