SERVICE INFORMATION

This bulletin contains a chart that lists the ECM Vendor serial number and cross-references to an Infiniti part number. This chart is intended to be used as a reference guide to determine that a vehicle hss the correct ECM installed in it. The parts catalog along with the VIN number and Date of Manufacture should be used to determine the correct part number when ordering a new ECM.

An ECM with a part number with 2371M-*****RE is a replacement ECM and should have the same programming as the original. If a vehicle has an ECM with a part number containing "M" and "RE" disregard the "M" and "RE" when using this chart.

On any CONSULT compatible vehicle the ECM part number can be accessed through the CONSULT connector using CONSULT. All other vehicles have a decal that has the vendor part number on the ECM cover.
