Attachment "A": ECM Reprogramming For Infiniti Vehicles

ECM Reprogramming involves two general steps:

^ Download the ECM Reprogramming data from ASIST to CONSULT-II.
^ Install the ECM Reprogramming data into the vehicle ECM.

CAUTION:
The ECM can be permanently damaged if the Reprogramming procedure is not followed exactly. Do not attempt Reprogramming if the vehicle or the CONSULT-II batteries are low. Do not disconnect or disturb the CONSULT-II while ECM Reprogramming is in progress. If the ECM is damaged, it must be replaced.
