Altima airbags and belts

Genuine OEM airbags and seat belts for the Nissan Altima

Altima parts come through this shop steadily, so it is worth checking the Altima listings before you call a dealer. The sedan was redesigned twice in the years we cover, in 2013 and again in 2019, and steering wheel bags, dash bags and belt retractors all changed with it, so every part is matched to your year and trim before it ships. If your original air bag diagnosis sensor unit survived the collision, mail it to us for a reset.

Air Bag Diagnosis Sensor Unit

Why the Altima airbag light stays on after a crash

Nissan calls the Altima airbag computer the air bag diagnosis sensor unit. It is the control unit for the supplemental restraint system. It receives signals from the front, side, and crash-zone sensors, watches the driver and passenger circuits through the spiral cable, fires the airbags and pretensioners in a crash, and writes a permanent deployment record into its memory. On the Altima it also keeps an eye on the occupant classification system.

Once that crash data is stored, the unit locks and the airbag light stays on. A standard OBD2 scanner cannot clear it because the hard codes live inside the sensor unit. Whether your Altima deployed one airbag or several, the unit has the crash on file and will not arm again until the data is cleared at the module level.

We reset your original Altima air bag diagnosis sensor unit in our shop, erase the stored crash data and hard codes, and return it factory-ready to plug back in. You keep the part Nissan built for your Altima. It holds its original VIN-matched coding and arms again the moment it is reinstalled.

Altima by generation

Altima generations and where the sensor unit lives

The Altima has run through several generations, and the diagnosis sensor unit settled under the center console on the floor. We reset every one from 1996 forward.

GenerationYearsModule location
L301998 to 2001Under the center console on the floor between the front seats
L312002 to 2006Under the center console assembly on the floor tunnel
L322007 to 2012Under the center console on the floor, behind the console trim
L332013 to 2018Under the center console assembly between the front seats
L342019 to presentLow and centered under the console on the floor

On an Altima you remove the center console trim and the surrounding panels to reach the unit, then unbolt it from the floor. Turn the ignition off, disconnect both battery cables, and wait at least three minutes before you touch any of the yellow SRS connectors, because the airbags and pretensioners can still deploy for about three minutes after the power comes off. Call us if yours is hard to find on your year.

Common Altima SRS codes

Altima airbag codes we clear every day

Nissan uses B-series SRS codes on the Altima. Deployment and crash-data codes clear with a reset. Open and short codes can point to the spiral cable or a part. Scan yours first.

What we fix on your Altima

Module reset and seat belts, by mail

We do two repairs for the Altima. We reset the original air bag diagnosis sensor unit and clear the stored crash data so the airbag light goes out. We also rebuild the Altima seat belts, because after a deployment the pretensioners fire, lock, and the webbing can seize. We restore single, dual, and triple-stage Altima belts and free locked retractors so they hold the way Nissan built them to.

We are honest about the limits. A module reset clears stored crash data. It is an electronics repair, so your Altima has to be mechanically safe and properly repaired before the system goes back in service. If a code points to the spiral cable or a damaged part rather than stored data, we tell you.
