Airbag control unit with part number B132M6206F

What does the airbag control unit B132M6206F do?

The control unit B132M6206F is the central control unit of the restraint system (SRS) of Lotus. It evaluates the signals from the crash sensors, decides within milliseconds in the event of an accident which airbags and seatbelt pretensioners to trigger, and monitors the system continuously.

If the unit detects a fault, it shows it via the airbag warning light in the instrument cluster. For the driver, this light is a clear warning that something is wrong with the restraint system.

After an accident, the control unit stores crash data and locks itself. The following section describes what can trigger a failure.

Why does the control unit B132M6206F fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. With this control unit, deleting the crash data is often not possible; if you would like it deleted, please contact Airbag24 briefly before sending the unit in. Other causes include aged components, moisture and voltage spikes.

A normal diagnostic tool cannot access this data, and it cannot be removed with one. An accident without airbag deployment can also leave such data behind.

In detail, the following points may apply:

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

How can you tell that the B132M6206F is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In a real emergency, airbags and seatbelt pretensioners may then fail to deploy.

If the light stays on after the ignition is switched on, have the restraint system checked promptly. However, the light alone does not identify the affected component.
