Definately switch cleaner. Clean and check connections to alternator & BECM also the earth leads around the engine bay. Use one of those brass bristle wire brushes..toothbrush size and make sure the battery is disconnected first so you don't short out across pins !!
Work the BECM connectors in & out to ensure the cleaner gets worked onto the contacts.
