Operation CHARM: Car repair manuals for everyone.

Malfunction Indicator Lamp (MIL)

The MIL (SERVICE ENGINE SOON) telltale is turned On by the cluster when it receives a command from the PCM. This indicates to the operator of the vehicle that there is a possible problem with the engine/transaxle control system.

The MIL will only be turned On for emission related faults.

During engine start-up, the MIL (SERVICE ENGINE SOON) telltale is turned On, for approximately 3 seconds, by the cluster for a bulb check.

The MIL will flash if a misfire is detected.
