Malfunction Indicator Lamp: Testing and Inspection

1. Connect terminal 1E of ECU to a body ground.
2. Start engine and check that MIL light illuminates.
3. If lamp does not light, check meter fuse, bulb and wiring harness between meter and ECU.

NOTE: With test connector grounded, ECU terminal 1E should read below 4.8V for 3 seconds after ignition is switched "ON" and MIL is lit. When MIL goes out, voltage should be approximately 12V.
