is
performed by

rear position sensors. Rear

the
RSS

module
which
controls compressor and exhaust solenoid operation.

will
run frequently for
a
few
seconds each

a
larger
air
leak the air compressor
may
stay on for up
to
seven
minutes.

should see
your
dealer for service, but
you
can
keep driving
your Cadillac.
