- Under the following conditions, the front passenger's airbag cutoff indicator stays on or comes on suddenly:
- When no one is sitting on the front passenger's seat, but there is an object on the seat more than 5 kg (11 lbs).
- The front seat belt is buckled, but no one is sitting on the front passenger's seat.
- Someone who is less than about 30 kg (66 lbs) is sitting on the front passenger's seat.
- Before replacing the SRS unit, check the SRS unit software version with the HDS. If the software version is not the latest, update the SRS unit software Testing and Inspection, and retest.

1. Check for these items, then recheck the front passenger's airbag cutoff indicator.

- The front passenger's seat is installed correctly.
- Nothing is/was on the front passenger's seat.
- Nothing is/was under the front passenger's seat.
- Nothing is/was in the front passenger's seat-back pocket.
