Airbag control unit with part number 1512876-00-D

What does the airbag control unit 1512876-00-D do?

The airbag control unit 1512876-00-D coordinates the SRS restraint system of Tesla. It processes what the crash sensors report and, in a crash, decides within a fraction of a second whether airbags and seatbelt pretensioners are triggered. To do this, it constantly monitors the system and shows faults via the airbag warning light.

After an accident, it stores crash data and locks itself.

The housing also carries the supplier number Bosch 0285020422.

Why does the control unit 1512876-00-D fail?

The most common cause with the 1512876-00-D is crash data stored after an accident, even if no airbag deployed. Other triggers include aged components, cold solder joints, moisture at plug connections and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 removes it during the repair.

The remaining causes relate to the age of the electronics, to connections and to the power supply. A weak battery or jump-starting can cause voltage spikes.

Which cause applies in the individual case only becomes clear during the inspection.

How can you tell that the 1512876-00-D is defective?

A fault in the 1512876-00-D shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Typical signs also include an error message in the instrument cluster, no connection for the diagnostic tool and a fault memory that cannot be cleared.

The signs at a glance:

• airbag warning light, permanently or intermittently
• error message in the instrument cluster
• no connection between diagnostic tool and control unit
• fault memory that cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not be able to deploy. Please have the findings checked promptly.
