What does the code 86-1 mean on a Honda Odessey?

86-1 is general communication issue it could be anything from a loose wire to a bad com module. You need an OBD test to narrow down the problem. Most car parts store will do the OBD test for free.

When I owned an Odyssey, I put my scanner on and got a code that was not on any list anywhere. When I took it to the dealer, they told me Honda has some codes only known to dealers. I said OK fix it, it's still under warranty. It was some sensor somewhere. They wouldn't tell me what the sensor does. HUH? I sold that POS. (After having numerous other problems)

It is a code for a fault with the ABS modulator circuit.
