CHECK ENGINE LAMP ON CONTINUOUSLY 4.10
GENERAL
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. See Figure 4-16.
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).
