Configuration (air Bag Diagnosis Sensor Unit) Nissan Pathfinder 2025

Description

Vehicle specification needs to be written with CONSULT because it is not written after replacing the air bag diagnosis sensor unit.

The configuration requires network connection. CONSULT connects to network and then it downloads the configuration data from the server. Then CONSULT writes the Nissan Pathfinder vehicle specification to the air bag diagnosis sensor unit.

Refer to Work Procedure.

NOTE:

For details the network connection and operation, refer to “CONSULT Operation Manual”.

The configuration no need to “save” configuration data from the air bag diagnosis sensor unit. The configuration data is always generated freshly at the server and then downloaded to the CONSULT.
