(a) Except as provided in subdivision (c), an order to pay any fine, restitution, or assessment, imposed as a condition of the grant of probation or as part of a judgment of conditional sentence for a violation of Section 23152 or 23153, may be enforced in the same manner provided for the enforcement of money judgments.
(b) A willful failure to pay any fine, restitution, or assessment during the term of probation is a
violation of the terms and conditions of probation.
(c) If an order to pay a fine as a condition of probation is stayed, a writ of execution shall not be issued, and any failure to pay the fine is not willful, until the stay is removed.
