Airbag control unit with part number 98820-5RL0B

What does the airbag control unit 98820-5RL0B do?

The airbag control unit 98820-5RL0B forms the control of the restraint system (SRS) for Nissan. It evaluates the crash sensors, determines the appropriate airbags and seatbelt pretensioners and triggers them within milliseconds in the event of an impact. After an accident it stores crash data and locks itself.

The unit checks the entire system continuously and shows faults via the airbag warning light in the instrument cluster. This makes it the control centre of the system.

Why does the control unit 98820-5RL0B fail?

Stored crash data is the most common cause for 98820-5RL0B, even if no airbag has deployed. Other possible triggers include aging of the electronics, moisture and voltage spikes.

With a standard diagnostic tool the crash data remains in place, whereas Airbag24 erases it during the repair.

Further causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump-start

How can you tell that the 98820-5RL0B is defective?

A defect in the 98820-5RL0B shows up first on the airbag warning light in the instrument cluster. Further signs that you can see in the vehicle and on the diagnostic tool are added to this.

• airbag warning light burning permanently or intermittently
• message in the instrument cluster
• diagnostic tool does not find the control unit
• fault memory remains, even after an attempt to clear it

In a crash, airbags and seatbelt pretensioners may then fail to deploy.
