Why is my LS400 malfunction indicator light (MIL) on?

If your LS400 has its malfunction warning light (more commonly called the check engine light) illuminated, it could indicate engine troubles, problems with the transmission, electrical issues, malfunctioning sensors, connector problems, or misfire issues.

Is it possible to reset the LS400 malfunction warning light on my own?

Resetting a malfunction warning light at home may be possible sometimes, but it is never recommended. The check engine light is commonly triggered by a misfire, fault or malfunction in one of the vehicle's systems. It is important to identify and fix the underlying problem to ensure the safety and reliability of the vehicle. Resetting the check engine light without addressing the underlying issue may temporarily remove the warning, but it will not fix the root cause of the problem.

Is the transmission considered part of the drivetrain in my LS400?

Yes, the drivetrain system in your LS400 includes the transmission. Other components in the drivetrain are the driveshaft, axles, and differential. Together, these components deliver power from the engine to the wheels to push your LS400 forward.
