Default VDC valve relay: where is it?

Good day!

I've recently had ABS/VDC warning icons lit up on my OBW '03MY. Controller diagnostic indicated an error code 51. Which, in turn, leads us to possible faulty VDC/ABS valve relay, but I'm confused where I can find this relay? Should I search the main relay box under the hood for it?

Thanks in advance!

I can only find reference that it's in 'the relay box', I assume that's the main relay box.

There's a 'valve relay' and a 'motor relay'

Thanks for your suggestion, Dave. I've got main fuse box inspected with no result. There are mostly fan, a/c and headlight relays. I found no VDC/ABS relays among them.
Where should I search next? Under the dashboard?
Looking through service manual isn't getting me any anywhere - I simply can't find any reference about this "the relay box" location...

If there's not a special VDC relay box under the hood, yeah, I'd try under the dash.


Maybe there's a relay box attached to the VDC control unit?

Dave is probably on the right track.

The 2003 VDC wiring diagram shows two connectors, F89 and F90 that are related to the relays. In the Front Wiring Harness diagram, these connectors are where the ABS/VDC unit is located, that is, engine compartment, right front fender. That would suggest the relays are next to, if not inside, the ABS/VDC unit.

Thanks for your info, guys! Unfortunately due to somewhat cold weather I've had to put off my investigation =)
