“Flashing” refers to reprogramming automotive engine control modules (ECMs). Almost all new vehicles today are now flash programmable. Computer reprogramming is an important part of repairs and tune-ups on most 1996 and newer cars. Many times, reprogramming is the only way to repair a vehicle and eliminate false “Check Engine Soon” lights or MIL indicators, and will often x engine and transmission problems that are not caused by mechanical issues.
