The next paragraph describes possible methods of overcoming a particular problem in newer systems. What are some of these methods?
The software in some newer systems is becoming more sophisticated and may check for a change in voltage or current over a period of time. Earlier systems would generate a fault code if a particular circuit was outside of the control parameters without reference to other data or circuits. More modern systems may consider the output from several components and relate one signal to another. Many vehicles are equipped with an SD warning light, usually located in the instrument panel on the facia. Codes transmitted by an ECM may be designated as 'slow codes' or 'last codes'.
Algumas possíveis formas de superar o problema em sistemas mais novos são:
- Verificar mudanças de tensão ou corrente ao longo do tempo;
- Considerar a saída de vários componentes e relacionar um sinal a outro;
- Utilizar códigos de falha designados como "códigos lentos" ou "últimos códigos".
