Need code explanation for ABS system

Hello guys,

need code for ABS system on Camry 1994, 4 cyl, 2.2 L engine with automatic trans.
Had visited mechanic friend of mine and he read :
"11 Solenoid Relay Circuit Fault" code, so I am interested what's that mean??
What's wrong with my ABS??
ABS light is constantly lighted on.

If you guys have any informations about this code and what means, how to fix it, and any other information about that, please feel free to drop me PM or email to linuxkingofnc@yahoo.com and it would be highly appreciated.

Thanks so much in advance.
