2009 Mazda trouble code

[Spyder]

I know its a mazda but I figured someone here might know...

Check engine light came on, scanned with OBD2 and CAN scanner. Code listed: CO121

Does any one have an idea? What little information I can find is Electronic Brake Control Module.

THanks.

Code says, "Valve Relay Circuit Malfunction"

I am thinking related to ABS?

Should be a standard OBD-II code. Probably more to do with the evap system.

^^ Note it's a "C" code, not "P", ie Chassis related.

Gotta love CANBus, very difficult to pull those codes on older vehicles.

I guess so. I called the local Mazda dealer and they said there isn't any such code in the Mazda database.
