Malfunction Indicator Lamp (MIL) (Service Engine Soon)

The MIL (SERVICE ENGINE SOON) telltale is turned ON by the cluster when it receives a command from the powertrain control module (PCM) (L61) engine or the body control module (BCM) (L81) engine. This indicates to the operator of the vehicle that there is a possible problem with the engine/transaxle control system.

The MIL (SERVICE ENGINE SOON) telltale 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 visual system check.
