and installation, or “zero point reset” is already performed.

• “Zero point reset current status” displays “Incomplete” if a new seat is installed. When turning key

switch ON without performing zero point reset, front passenger air bag OFF indicator turns ON.

When zero point reset is performed, front passenger air bag OFF indicator turns OFF.

• Air bag warning lamp blinks in user mode only.

• Air bag sensor unit does not record whether or not zero point reset is performed.
Is condition “ALREADY PERFORMED”?

YES

>> Print out “ZERO POINT RESET CURRENT STATUS” screen, and inspection end.

NO

>> Check condition as per the following, and perform zero point reset again.

• Passenger seat is occupied by an object.

• Excessive vibration is applied while performing zero point reset.

• Occupant detection system is malfunctioning.

NOTE:

If “Incomplete” is displayed on “zero point reset current status”, zero point reset is not completed

normally. Check the condition as per the following and perform zero point reset again.

• Passenger seat is occupied by an object.

• Excessive vibration is applied while performing zero point reset.

• Occupant detection system is malfunctioning.
