The security alarm?
ECM is a part of Nissan Anti-Theft System (NATS). Replacement ECM must have immobilizer code
rewritten, using CONSULT. To perform rewrite procedure requires the vehicle, all keys and a
CONSULT tester with a NATS Program Card (E960U). Any key not learned during rewrite will not
start vehicle. Follow CONSULT tester instructions
