Airbag control unit with part number 13586631

What does the airbag control unit 13586631 do?

The airbag control unit 13586631 is the central control unit of the restraint system (SRS) for Opel. It evaluates the crash sensors and decides within milliseconds on the triggering of airbags and seatbelt pretensioners.

The unit monitors the system continuously and shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit 13586631 fail?

The most frequent cause is stored crash data after an accident, even if no airbag fired; a normal diagnostic tool cannot erase it. Further causes are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Aged electronic components wear out over time, and cold solder joints can interrupt contacts. Moisture and corrosion disturb signal transmission at the plug connectors.

Voltage spikes, for example from a weak battery or a jump start, additionally stress the electronics. During the repair Airbag24 erases the crash data, and the test shows which further cause is present.

How can you tell that the 13586631 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. The diagnostic tool gets no connection to the control unit, and a fault memory cannot be cleared. Airbags and seatbelt pretensioners may then fail to trigger in an emergency.

The signs in detail:

• The airbag warning light stays on permanently or comes on intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool does not establish a connection to the control unit.
• The fault memory cannot be cleared.

If you see one of these signs, have the fault memory read out before you change anything in the system.
