Diagnóstico obd2 de vehículos

¿El motor de su carro no está sonando bien?
¿Hay algo raro en la manera en que su carro se está comportando?
¿Ha perdido fuerza? ¿Gasta más combustible?
¿Está encendida la luz CHECK ENGINE en su tablero? ¿Y las luces ABS, SRS, ESP, etc.?
¿Problemas en la dirección? ¿En la transmisión? ¿En el motor? ¿Fallas en la emisión de gases?
¿Fallas electrónicas en sistemas de la carrocería? ¿Problemas intermitentes?
¿Pensando en comprar un vehículo y preocupado por las fallas ocultas que pueda tener?
¿Frustrado porque no hay quien pueda diagnosticar su carro con precisión?
Desde hace años los carros vienen incorporando mucha tecnología para su funcionamiento. Son fabricados con complejos sistemas
interconectados. La computadora abordo (OBD) monitorea continuamente el rendimiento de los sistemas de un vehículo. Cuando un sensor
envía señales fuera de rango, se trata de una falla que puede llegar a encender una luz en el tablero y grabar un código de falla en la
memoria. Estos códigos deben ser recuperados e interpretados por un escaner profesional de diagnóstico. Si decide ignorar las luces de
advertencia del tablero porque el carro aparentemente está funcionando bien, hay riesgo severo de daño del motor u otros componentes. Si se
enciende la luz CHECK ENGINE, el carro está emitiendo gases contaminantes muy por encima de lo permitido debido a problemas en el
sistema del motor.
Escanear un vehículo en motor apagado permite:
Recuperar y eliminar los códigos de falla genéricos y específicos confirmados durante su recorrido.
Obtener los valores de los sensores del instante de la falla.
Obtener los resultados de las pruebas de los sensores de oxígeno.
Verificar y reiniciar el estado de los monitores de sistemas relacionados con la emisión de gases.
Escanear un vehículo en motor apagado no revela las fallas o incoherencias que sus sistemas podrían tener durante la marcha. El diagnóstico
en motor funcionando, permite:
Obtener y registrar las lecturas en vivo de los sensores del vehículo durante la marcha y en el momento de una falla.
Comparar las lecturas simultáneas de distintos sensores para identificar las fallas e incoherencias entre sí.
Determinar el consumo y la economía del combustible.
Determinar los caballos de fuerza (potencia) y el torque del vehículo (momento).

Caso de Estudio
El automóvil Mercedes de un propietario del interior del país se paraba cada vez que el carro picaba o hacía fuerza. En talleres de prestigio
escanearon el carro en motor apagado pero no encontraron ningún código de falla. Dijeron que se trataba de un problema de alineado y
balanceado de llantas, etc. Y ya no recibieron al carro "por falta de tiempo". Entonces, el propietario optó por las pruebas en vivo para dar con
el problema del carro. Mientras él conducía por una exigente avenida de La Paz, un ingeniero iba de copiloto con un escáner profesional
conectado al enchufe OBD2 del mercedes. Luego de monitorear en vivo otros sensores, se encontró que, el flujometro enviaba lecturas
incoherentes cuando el carro se detenía por sí solo. Se desconectó el flujometro y la computadora del mercedes entró en modo seguro.
Aunque el carro sin flujometro consumía más gasolina, ya no se detenía. Finalmente, se remplazó dicho repuesto y el mercedes ahora está
funcionando bien.
