Tip & How-To about Cars & Trucks
The automotive onboard computer modules is a very complex device that is programmed to control and monitor specific aspects of a specific automobile. The ECM is the most referred to but it is not the only onboard. For example the 2014 Lincoln MX has 39 (and this car these modules all collaborate with each other the control the operation of the car and they do so wireless. Consider this when contemplating working or replacing one.
1. You may think it is the ECM, but it could be one of the modules giving the ECM false data. Alright - which one do you replace or fix. Unless you have had the problem specifically diagnosed that it is a specific module that has failed or is ailing (short of a module having been physically damaged, you won't know.
2. If you go out an acquire another module it is going to be flashed (clear it and reload a new set of program instructions). (the module is costly to acquire - even from a wrecker)
3. In order to flash the module you first need the "program Instructions" from the manufacturer. (usually their database and you need access to that - that is costly.
4. Then you need the computer gear from the manufacturer - to hook up to the car in order to carry out the flash. (another costly item)
5. You are far better spending your money at the dealer or a shop with the correct equipment.Spend the couple hundred bucks and send it to either a dealer, a shop that has the equipment, or a mobile service company that specializes in flashing modules. (you need to flash the one that is failing or failed or the newly acquired one)
