Airbag control unit with part number 8201214996

What does the airbag control unit 8201214996 do?

The airbag control unit 8201214996 is the central control unit of the restraint system (SRS) in Renault. It evaluates the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered. Faults are reported via the airbag warning light.

In normal operation the unit continuously monitors the entire trigger chain, i.e. sensors, wiring harness and trigger units. It also checks its own function. If it detects a deviation, it creates an entry in the fault memory.

After an accident the unit stores crash data and locks itself. Anyone who later wants to trace the state of the system will find this information in the fault memory.

Why does the control unit 8201214996 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes include ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or jump-starting.

An accident does not have to have led to an airbag deployment for crash data to be stored in the memory. The data remain in the unit even if the vehicle continues to drive normally afterwards.

The other causes can lie in the electronics and the connections. Age-related components lose reliability over time, and solder joints can give way. Moisture and salt corrode plug contacts, and a voltage dip in the on-board electrical system can disrupt the unit.

How can you tell that the 8201214996 is defective?

The airbag warning light in the instrument cluster lights up permanently or comes on intermittently. An error message may also appear in the instrument cluster, and the diagnostic tool may be unable to connect to the control unit. In that case, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

The warning light is the clearest sign the vehicle gives. If the fault memory also cannot be cleared, this points to a fault in the system.

If you ignore the warning for an extended period, you are driving with a restraint system whose function has not been confirmed. Please take the warning seriously and have the system checked.

Which vehicles is the 8201214996 fitted in?

The control unit 8201214996 is fitted in these vehicles: Renault Kangoo II (2008-2021).

The assignment to vehicles works out in detail as follows:

• Renault Kangoo II (2008-2021)

Before removal, compare the part number on the label of the unit with this page. This only confirms that you have the correct unit in front of you. Also have the fault memory read out beforehand, because only this log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 2840211503, 8200 656 329, 8200656331, 8201 229 153 A, 8201 475 929, 8201025624.

How does the repair of the 8201214996 work?

First have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the control unit. Next, create a repair order online and send in the well-packed unit. Processing at Airbag24, i.e. inspection, repair and function test, usually takes 3–4 working days.

The sequence is fixed for safety reasons. Without a secured fault memory and a disconnected battery, removal does not begin.

At Airbag24 the team inspects the unit on the test bench and repairs defective components. Airbag24 deletes stored crash data during the repair, and a function test completes the process. The unit then returns to you.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 8201214996 get to Airbag24?

You send the control unit as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns the unit to you by UPS.

Place the printed repair order in the parcel and pack the unit shockproof. This protects it well during transport.
