1996 Toyota Land Cruiser Q&A
1996 Toyota Land Cruiser Question: my check engine light is on can you tell me why?
Many many things can bring on the light, you need a scan tool to retrieve codes stored in order to give advice. The computer constantly monitors the components in your car to see they are there and functioning within performance limits. If the fault goes away or was false the computer monitors the problem if it goes away the light turns itself off. - patrick mannion
