air bag light

i replaced the oe steering wheel with a carbon fiber wheel. afterwards the air bag light is on. the battery is fully charged & was never low. before the R&R, i turned off the power via cutoff in trunk. car is a 2001 360. had to have been easiest wheel i've changed & i've removed a bunch. air bag pins have continuity that ohms the same as other bags i've checked. clockspring also seems to check ok. all connections seem proper. i see in the owners manual "never remove steering wheel. this operation, when needed, must be performed by authorized personnel of the ferrari assistance network". so i'm thinking maybe any disturbance of air bag may cause a code. i have a snapon modis scan tool which is very limited & tells me nothing on air bag codes. i checked past threads with no help. don't mean to ramble on, but i would like to kill the light (not pull bulb). so my question is, anybody know how to pull codes? or clear codes? thanks for any input
