Airbag control unit with part number B132M6067F

What does the airbag control unit B132M6067F do?

The control unit B132M6067F is the central control unit of the restraint system (SRS) for Lotus. It checks the signals from the crash sensors and, in an emergency, determines which airbags and seatbelt pretensioners trigger. After an accident, it stores crash data and locks itself.

In everyday use, the system runs continuously in the background. The control unit monitors the connections to sensors, actuators and warning lights, and reports detected faults via the airbag warning light in the instrument cluster.

Because triggering takes place within milliseconds, the decision is time-critical. For this reason, the unit evaluates the measured values continuously rather than only at the moment of an impact.

Why does the control unit B132M6067F 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, contact Airbag24 briefly before sending the unit in, so that they can check the part number. Other possible causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be deleted with a normal diagnostic tool, which is why it is one of the causes to keep in mind first when troubleshooting.

Voltage spikes occur, for example, with a weak battery or when starting with jump leads. They too are among the influences that can take their toll on the electronics.

How can you tell that the B132M6067F is defective?

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

The light is the most visible sign, because it needs no tools. Have the finding checked as soon as it stays on permanently or recurs.

Even a fault that occurs only intermittently belongs in the check, because the warning light is precisely for that purpose.

Which vehicles is the B132M6067F fitted in?

Two things help with the assignment. Compare the part number on the label of the unit with this page; this ensures that it is the correct unit. Also have the fault memory read out before removal, because only this result 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 A132M0208F, B132M6206F.

How does the repair of the B132M6067F work?

The order is mandatory for safety reasons: first have the fault memory read out and enclose the log with the unit, then disconnect the battery and only then remove the control unit. Next, create a repair order online and send the unit in well packed. Processing at Airbag24 usually takes 3–4 working days.

At Airbag24, the control unit is examined on the test bench. Airbag24 replaces defective components, followed by a function test, and then your own, repaired unit is returned to you.

If you would like the crash data deleted, contact Airbag24 briefly before sending the unit in.

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 B132M6067F get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge; after the repair, Airbag24 returns it by UPS.

Place the printed repair order in the parcel and pack the unit shockproof.
