'99 Ls Speedo Not Working - Sender Or Instrument Cluster

[dthouston]

The speedo on my '99 LS400 finally died. It has had the "reads 0 for the first 20 miles" problem that seems to be common for the past couple of years. But now I think it's really died.

How do I determine if the problem is the sender or the instrument cluster?

The odometer is still working, so that tells me that at least something is sending a signal.

But are there multiple senders on the '99 LS? (like maybe the one feeding the speedo has died but the one feeding the odometer is is OK).

I've found a company that will remanufacture my instrument cluster for $175 (us-sales@bba-reman.com), but I want to make sure the speedo is really the problem.

(BTW: has anyone used bba-reman?)

TIA
