As a functional test, the Check Engine Light illuminates at key-on before
engine cranking. Whenever the Powertrain Control Module (PCM) sets a
Diagnostic Trouble Code (DTC) that affects vehicle emissions, it
illuminates the Check Engine Light. If a problem is detected, the PCM
sends a message over the J1850 Bus to the instrument cluster to illuminate
the lamp. The PCM illuminates the MIL only for DTC's that affect vehicle
emissions. The MIL stays on continuously when the PCM has entered a
Limp-In
mode or identified a failed emission component or system. The MIL remains on
until the DTC is erased. Refer to the Diagnostic
Trouble Code
charts in this group for emission related codes.
Also, the Check Engine Light either flashes or illuminates continuously when
the
PCM detects active engine misfire. Refer to Misfire Monitoring in this
section.
Additionally, the PCM may reset (turn off) the MIL when one of the following
occur:
A Diagnostic Trouble Code (DTC) indicates the PCM has recognized an
abnormal condition in the system.
Remember that DTC's are the result of a system or circuit failure, but
do not directly identify the failed component or components.
Each time the ignition key is turned to the ON position, the
malfunction indicator (check engine) lamp on the instrument panel
should illuminate for approximately 2 seconds then go out. This is done
for a bulb check.
