Malfunction Indicator Light (Mil)
All models are equipped with a MIL (or CHECK ENGINE light). Light comes on if component related to fuel injection and/or ignition system fails. MIL is installed in oil temperature/pressure gauge cluster. Light comes on as a self-test when ignition switch is in ON position.
After engine starts, throttle valve closes and MIL goes out to indicate no codes are present. If MIL remains on, a fault is present (hard failure) in DME engine management system. If MIL comes on (flickers) while vehicle is driven, a fault in DME engine management system has been identified (intermittent failure).
If idle speed switch is open during starting, MIL will come on. As soon as idle speed switch closes while vehicle is driven, MIL goes out after a 4-second delay.
If full throttle switch is faulty (shorted to ground), MIL will remain on constantly. Some fault codes cannot be displayed using MIL. In such cases, retrieve fault codes through diagnostic connector, and repair conditions causing MIL to come on. See USING DIAGNOSTIC CONNECTOR under RETRIEVING CODES. See Fig 1 or Fig 2 .
