What is the difference between a Electronic control module and Engine control module?
I recently bought a cheap Ford Focus which was affected in floods… I got the water of the engine and pretty much all the places, all my lights and few other electronic functions work… But my engine doesn't turn on and my HUD is dead, but works on another car… What should i do?
Those names are too vague to be exact.
JUNK ITS, ITS NOTHING BUT PROBLEMS WITH FLOOD CARS I BOUGHT A RANGE ROVER 2013, FLOOD CAR, SPENT OVER $8000.TRYING TO REPAIR IT, WE NEVER GOT IT TO START, SOLD IT FOR PARTS, TOOK A $6000. LOSS NEVER AGAIN
I don't know what an HUD is. Is it for birth control? Housing development?
Its never going to be 'fixed'. That's why the title had to denote 'flood'.
Take it to the dealer. They have the factory scan tool that can diagnose if you have communication problems in the electrical system. ECU, ECM, are pretty much the same thing. If your vehicle is an automatic it's called a PCM.
An electronic control module could be for anything. Engine control module usually just runs the engine. Now days cars often have a body control module and a power train control module. Powertrain runs things like engine, transmission, traction control, and ABS brakes. Body control module runs pretty much every other electric thing in the car.
Modern cars that were in floods are bad news. You could have just a little water in one plug somewhere in the car that will keep it from ever working correctly. Or worse yet you get it working now then next week you hit a bump and that one connector goes bad again. Only way to be sure its going to be reliable is to replace every electrical part and wire.
- What is the difference between a Chevy and a Ford? And where can I get a book on how to know all about vehicles? Pretty much a "for dummies" book on vehicles lol.
- What is the difference between a boat inboard motor and a car motor? I need to replace the motor in my boat and I have a Ford 300 6 cyl. Engine in my back yard. Can i use it for the boat? What needs to be modified?
- What's the difference between the map light and dome light? I have a 2003 Ford Taurus SES sedan. I want to put LED interior lights. I was looking it up and I has dome and map lights? So I looked up the difference and the only thing that kept showing was the overhead dome housing?
- Weight difference between I/O and Outboard boat? I've been looking at used boats and I noticed that boats that have an I/O engine are about twice the weight of boats that have an outboard motor. For example, a 17' bowrider with an I/O sterndrive weights almost 2000 lbs, whereas a 17' Outboard bowrider only weighs about 900 lbs. Does this sound right to you guys? Weight does matter to me because my towing vehicle would be a V6 Ford Ranger.
