HDS Software Bug Causes Bogus VSA DTC 98 (Rev: Jan 05)
If you use the HDS to clear a stored VSA DTC in a '00 04 RL, you'll wind up with a VSA DTC 98. You won't find this DTC in the 2000 - 2004 RL S/M; it's bogus. Blame it on a bug in the HDS software. Until the HDS software gets fixed, you need to manually clear the VSA control unit to get rid of this bad boy.
