CHECK ENGINE LAMP ON CONTINUOUSLY

GENERAL
See Figure 4-16. If the engine stop switch is set to RUN with
the engine off, and the ignition key switch is turned ON, the
check engine lamp should illuminate for four seconds.
Following the initial period of illumination, the lamp should go
off for four seconds. It may then come back on for an eight
second period (for a stored error) or remain on continuously
(current error).
