Airbag control unit with part number 8200272511

What does the airbag control unit 8200272511 do?

The airbag control unit 8200272511 controls the restraint system, SRS for short, in the Renault. It analyses the signals from the crash sensors, determines within milliseconds in a crash which airbags and seatbelt pretensioners trigger, and checks the entire system constantly. After an accident it stores crash data and locks itself.

Monitoring runs throughout the whole journey. If the unit detects a fault, it creates an entry in the fault memory and shows it via the airbag warning light in the instrument cluster. It also checks the wiring of the ignition circuits and the power supply.

The lock after an accident is not noticeable in normal operation. Whoever wants to read out the unit notices it only during diagnosis.

Why does the control unit 8200272511 fail?

Most common cause is crash data from an earlier accident, even if no airbag has deployed; a normal diagnostic tool cannot remove it. In addition there are ageing electronics, cold solder joints, moisture and corrosion at plugs, and voltage spikes.

After an accident, crash data stays stored in the unit, regardless of whether an airbag or seatbelt pretensioner has deployed. It remains there until it is deleted during the repair.

Further causes that occur with control units of this type:

• aged electronic components
• cold solder joints on the circuit board
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 8200272511 is defective?

A defect is indicated by the airbag warning light in the instrument cluster, which burns permanently or intermittently, as well as by a fault message in the instrument cluster, a missing connection between the diagnostic tool and the control unit, or a fault memory that cannot be cleared.

Typical signs are:

• The airbag warning light burns permanently or flickers intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool cannot establish a connection to the control unit.
• The fault memory cannot be cleared.

Airbags and seatbelt pretensioners may in an emergency not deploy as long as one of these points applies. Therefore react promptly.

First compare the part number on the label of the removed unit with this page. This only confirms that it is the right unit. Also have the fault memory read out before removal, because only the 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 600589600, 604649100, 605044900, 606083300, 8200098401, 8200098402.
