What does it mean when the ECD light comes on in a car?

When the ECD light comes on in a car, it indicates that the energy-saving mode has been activated. Below is relevant information about ECD: Concept: It is the most sensitive gas chromatography detector and also the earliest selective detector. Function: It only responds to compounds that can capture electrons, such as halogenated hydrocarbons, and compounds containing heteroatoms like N, O, and S. With high sensitivity and good selectivity, it has been widely used for years in analyzing trace amounts of pesticides, polychlorinated biphenyls, etc., in environmental samples. Its application scope is second only to TCD and FID, consistently ranking third. ECD is one of the gas ionization detectors.
The ECD light usually indicates a problem with the car's electronic control system. I've encountered a similar situation while driving myself. This light is often related to engine management, emission control, or anti-skid systems. Consider whether it's a diesel vehicle or a new car, as many modern vehicles have this indicator light, meaning a sensor is faulty or the computer control part isn't functioning properly. You need to pay attention promptly, otherwise it may affect the car's power or fuel consumption, and even sudden stalling on the road can be dangerous. I suggest not driving too fast first, find a safe place to park, then quickly check the user manual for the specific meaning of the light. It's best to go to a repair shop as soon as possible to scan the diagnostic tool for trouble codes, to avoid small issues becoming bigger and costing more money.
