Airbag control unit with part number 98820-1KC0A

What does the airbag control unit 98820-1KC0A do?

The airbag control unit 98820-1KC0A belongs to the SRS restraint system of Nissan vehicles. It reads the crash sensors, determines within milliseconds which airbags and seatbelt pretensioners to trigger, and checks the system at all times. If it detects a fault, the airbag warning light comes on.

After an accident the unit stores crash data and locks itself. It also keeps the fault memory and establishes the connection to the diagnostic tool.

Why does the control unit 98820-1KC0A fail?

The most common cause with 98820-1KC0A is crash data stored after an accident; it remains even if no airbag has deployed, and a normal diagnostic tool does not erase it. Other causes include aging electronics, cold solder joints, moisture or corrosion, and voltage spikes.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting

Stored crash data only shows up when it is read out with the diagnostic tool, because no airbag has to have deployed for it.

The other points tend to develop over time, which is why it is worth looking at the plug connections when the unit is read out.

How can you tell that the 98820-1KC0A is defective?

The airbag warning light in the instrument cluster lights up on the 98820-1KC0A permanently or intermittently, and a fault message also appears in the instrument cluster. The diagnostic tool cannot reach the control unit, and the fault memory cannot be erased.

Signs like these mean that airbags and seatbelt pretensioners may not deploy in an emergency. The warning light going out again is no all-clear either, because the fault entry may still be there.

A check is therefore advisable as soon as the light appears.
