Installation and Replacement: The BSM R05-00 is housed in a plastic casing located in the engine bay next to the battery. Before removal, disconnect the positive battery terminal to ensure safety. Loosen the 13 mm nut securing the unit. Carefully disconnect all connectors except one, which is used to gently pull the unit out towards you.
