Catalytic converters stolen how to reset computer
Well its hard to diagnose with the little info given. Did you replace the catalytic converter with a new one, an aftermarket one, or just weld straight pipe instead? But in order to totally reset the ECU/PCU, or any controller for that matter, you disconnect the negative cable on the battery for several minutes and turn the ignition switch to the on position, then off, then on, ect a few times to discharge any remaining electricity that may be stored in the controllers. This will reset all data stored in the controllers, which will then reset all of your sensors. Some controllers may have to be further programmed through software by OBDII connection.
