Airbag control unit with part number 98820W031P

What does the airbag control unit 98820W031P do?

The airbag control unit 98820W031P is responsible for the restraint system in Mitsubishi vehicles. It evaluates the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and checks the system permanently for faults.

If it detects a fault, it writes it into the fault memory and displays it via the airbag warning light.

After an accident, the control unit secures crash data and locks itself. The next section explains this in more detail.

Why does the control unit 98820W031P fail?

The most common cause of the 98820W031P failing is crash data from an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Further causes at a glance:

• ageing of the electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery

The crash data remains stored until it is erased during the repair.

The other causes cannot be separated without measurement, which is why testing comes first.

How can you tell that the 98820W031P is defective?

Signs on the 98820W031P are an airbag warning light that stays on permanently or from time to time, an error message on the display and a diagnostic tool that cannot establish a connection. The fault memory then cannot be cleared. In an emergency, airbags and seatbelt pretensioners may fail to deploy.

• Airbag warning light, permanently or from time to time
• Error message in the instrument cluster
• No connection to the diagnostic tool
• Fault memory cannot be cleared

The warning light is a clear sign that something is wrong in the restraint system.

If it stays on after the ignition is switched on, have the fault memory read out before taking any further steps.
