Most vacuum errors can be narrowed to either
the regulator or the power distribution board
and associated wiring harness. To determine
which has failed, swap the connectors for the
large and small tank regulators. If the problem
occurs in the other canister after the switch,
then the regulator is bad. (part of the vacuum
manifold assembly P/N 0702-001-110) If not,
then proceed to check the wiring harness and
power distribution board.
