Airbag control unit with part number 8201719760

What does the airbag control unit 8201719760 do?

The airbag control unit 8201719760 carries out the control of the SRS restraint system in the vehicle from Renault. It receives the signals from the crash sensors, evaluates them and determines in an accident which airbags and seatbelt pretensioners are triggered. It also checks the system continuously for faults.

The unit works in the background. If it reports a fault, it shows this via the airbag warning light in the instrument cluster so that you can respond.

After an accident, the control unit stores crash data and locks itself. This state ends only with a repair.

Why does the control unit 8201719760 fail?

The most common cause is that crash data was stored after an accident, even without an airbag having deployed. Further causes include aged components, cold solder joints, moisture at plug connectors and voltage spikes. With the 8201719760, only the test shows which cause applies.

Crash data remains even after a diagnostic tool is connected, until Airbag24 removes it during the repair.

Aged components and cold solder joints impair the function. Moisture and corrosion disrupt the contact at plug connectors.

Voltage spikes, for example with a weak battery or after a jump start, put additional strain on the electronics.

How can you tell that the 8201719760 is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently if the 8201719760 has a fault. In addition, a fault message may appear and the diagnostic tool finds no connection to the control unit.

• Airbag warning light that lights up constantly or intermittently
