Odyssey ABS trouble

The ABS, TCS, & Brake lights are lit up continuously on the dash and the ABS system is inop. Wheels will lock up if tested. Dealer hooked up to computer and codes said there was an error with the right, front ABS/TCS. They said it was probably a relay but would have to troubleshoot to id the exact problem.

I want to try to fix myself. I need help locating the relay(s) that might be faulty. Also, is there any other possible items that could be faulty and produce the same symptoms?

Thanks.

the relays for the abs should be under the hood in the fuse box. goto a honda dealer and have them print up the tolerances for the relay(V, Ohms, etc) and test them out.
