ECM Programming

After disconnecting battery or replacing ECM, drive vehicle to enable ECM to relearn driveability. Inform your customer that they may experience driveability different from what they are accustomed to until ECM completes relearn function.

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