Airbag control unit with part number 98820-5JM0A

What does the airbag control unit 98820-5JM0A do?

As the central control unit of the restraint system (SRS) of Renault, the airbag control unit 98820-5JM0A evaluates the signals from the crash sensors. In an accident it decides within milliseconds which airbags and seatbelt pretensioners are triggered.

It monitors the system throughout operation and shows faults via the airbag warning light in the instrument cluster. If the vehicle has been in an accident, the unit creates crash data and remains locked afterwards.

Without this control, the restraint technology cannot fulfil its task in an emergency.

Why does the control unit 98820-5JM0A fail?

Crash data stored after an accident is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase it. In addition, aged components, cold solder joints, moisture and corrosion at plug connections and voltage spikes come into consideration.

Crash data remains stored in the unit until it is erased.

Aged electronic components and cold solder joints can cause problems that do not show immediately. Moisture and corrosion, by contrast, impair the contact at the plug connections.

Voltage spikes, for example from a weak battery or a jump start, additionally strain the electronics.

How can you tell that the 98820-5JM0A is defective?

A defect shows through the airbag warning light, which stays on permanently or intermittently. In addition, a fault message in the instrument cluster, no contact with the diagnostic tool and a fault memory that cannot be cleared point to a problem.

If one of these signs is present, airbags and seatbelt pretensioners may fail to trigger in an emergency. The warning light shows the defect, and a prompt check is therefore advisable.
