The P1212 code on your 2002 Infiniti I35, means that the ABS Control unit (attached to the ABS actuator) is not communicating with the Engine Control Module (ECM). Either one of the units or the connectors and wires between the units are fealty. I suggest starting by inspecting the ABS control unit connector (disconnect and reconnect) and clear the code. If the codes comes back, then you should have a technician inspect your vehicle for further testing, because you may have a faulty ABS control unit. The ABS actuator is on the driver side of the engine, next to the firewall.
