...sparking is an electrical problem of some sort.
I'm not sure what you intended to say. My paragraph before was trying to tell how easy a lamp indication on a panel can be misinterpreted into something else - a lamp that only flashes at max acceleration is quite easy to think of as a ECU-detected problem with the engine. When in reality it's the lamp beside the ECU lamp that flashes for some tenths of a second to tell that the fluid level is low because of the acceleration. The linked article was about someone driving in a roundabout and believing that the warning light was caued by external, electrical, interference. I.e. another misinterpretation of a flashing warning light. The issue here is that maybe the warning lights should have a significant hysterese so they do not get trigged by g forces. Most probably, the filter times used is adapted to avoid false trigging by bumps, but acceleration or driving fast through a roundabout allows the sensor to pick up the "error condition" for longer than the programmed filter time. The trouble is to figure out what is a reasonable filter time. For break fluid, you want the lamp to warn directly, in case of a brake tube rupture. Even with multiple brake circuits, uneven brake force on the four wheels could make life quite interesting in slick road conditions. |
