INFOID:0000000009946090

This Occupant Detection System has the following functions.

• Suppress the deployment of passenger air bag when passenger seat is empty, or when occupied by child

and child-seat. 

• Turns ON passenger air bag OFF indicator when passenger seat is occupied by child-seat and child.
• Indicates malfunction portion with blinking times of air bag warning lamp in diagnosis mode.
• Indicates the malfunctioning record by CONSULT.
• When “zero point reset” for Occupant Detection System is incomplete, CONSULT indicates that “zero point

reset” is incomplete. This function is applied to NISSAN genuine parts only.

NOTE:
• Operation of air bag diagnosis sensor unit when air bag diagnosis sensor unit receives information from

Occupant Detection System.

• Even if zero point reset is “complete”, always perform zero point reset after the removal and installation of

seat or the removal of control unit harness connector.
