have a 2002 hyundai xg350 with a bad wiring harness could this damage the computer also and any other parts
if the wiring harness is no good can it possibly effect other components ie the ecm or any other sensors i would hate to replace harness and then find out there are other problems
There is a chance it may have damaged the ECU, but the only way to find out is to test it on another car or to replace the harness. Some sensors need a 5 volt reference voltage to work and may be damaged by overvoltage (12 volt for example), it really depends on how and in what way the wiring harness was damaged.
