A Friend of mine has a G35 sedan and he gets DTC code B1018 and this all has to do with the passenger front seat airbag sensor/pressuremat which will not detect a passenger in the seat and so not protect the passenger with airbag deployment in case of a collission.

My friend went to the dealer who inspected the fault and came to the conclusion that it was not DTC code 1022 in case of the recall. but next:

answer:
"The failure that emerges is the fault code DTC B1018 (occupant
sens unit fail)
This is a sensor in the seat of the chair RH which senses if anyone is sitting on the right passenger seat

From one of your mails to us, you thought there might have been a recall
of Infiniti, which also refers to the interference.
We therefore have the cable / connector and the sensor measured with special tools/measurement of Infiniti Europe (Switzerland) to tracet his error.

This measurement is performed at our office in Amsterdam.
These measurements showed that there are no deficiencies that lead to the
failure of the recall.
In the bulletin of the recall is stated that it is a DTC code 1022
which will be referred to the same component but not the same fault
is.

Furthermore, we have attempted to correct the interference by unplugging the occupant sensor under the RH seat connect three wires directly
by soldering, unfortunately without result because the error keeps coming back.

Our final diagnosis is that the fault of the occupant sensor, which
in the seat of the chair seat intrigued RV's, this means that the
entire seat portion of the RH seat must be replaced.
Further information shows that when the occupant sensor is replaced,
the diagnosis sensor unit named the ACU must be replaced.

The cost of the chair frame plus sensors is 5345.78 euros and replace
diagnosis unit 1,045.44 euros VAT included (these components are currently
not in stock at Infiniti)
Incidentally, this is excluding installation costs.

I added a description of the diagnosis and DTC B1018"
End of quote

So that can cost a lot of money.
However I read there is a replacement seat sensor pad that can be installed in the seat cushion in stead of replacing the whole seat cushion.

Can someone of the experts amongst you respond to this problem

Thanks
