El fusible 1 alimenta el RVS y el PEV (si est\u00e1 presente). Cuando el fusible 1 est\u00e1 abierto, ninguno de estos componentes funcionar\u00e1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Las unidades de CA funcionar\u00e1n si el diferencial de presi\u00f3n est\u00e1 por debajo del umbral de arranque m\u00e1ximo permitido (100 psi), pero las unidades de bomba de calor (HP) no funcionar\u00e1n en absoluto. El c\u00f3digo se borrar\u00e1 una vez que se elimine el cortocircuito y se reemplaze el fusible por una pieza nueva y sin da\u00f1os. Si el fusible est\u00e1 fundido, es probable que haya un cortocircuito en los arneses del PEV o del RVS. Si no se observan da\u00f1os f\u00edsicos, comience por desconectar todos los componentes del PCM y realice conexiones hasta que el fusible de repuesto se abra. El arn\u00e9s debe repararse antes de reemplazar el fusible. Consulte el diagrama de cableado para conocer el tama\u00f1o y la ubicaci\u00f3n del fusible.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p
