Dodge 2008 Ram Pickup 1500 - Manual (Page 451)

5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will blink for approximately five seconds
and then remain on until the first engine crank or the
key is turned off. This means that your vehicle’s OBD
system is not ready and you should not proceed to the
I/M station.
b. The MIL will remain fully illuminated until the first
engine crank or the key is turned off. This means that
your vehicle’s OBD system is ready and you can
proceed to the I/M station.
If your OBD system is not ready, you should see your
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
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
REPLACEMENT PARTS

maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-Mopar

and repairs will not be covered by the manufacturer’s
