• The MIL will not flash at all and will remain
fully illuminated until you place the igni-
tion in the off position or start the engine.
This means that your vehicle's OBD II sys-
tem is
ready and you can proceed to the I/M
station.
If your OBD II system is not ready, you should
see an authorized dealer or repair facility. If
your vehicle was recently serviced or had a
battery failure or replacement, you may need
to do nothing more than drive your vehicle as
you normally would in order for your OBD II
system to update. A recheck with the above
test routine may then indicate that the sys-
tem is
now ready .
Regardless of whether your vehicle's OBD II
system is ready or not, if the MIL is illumi-
nated during normal vehicle operation you
should have your vehicle serviced before go-
ing to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the
engine running.
