Airbag control unit with part number 13505636

What does the airbag control unit 13505636 do?

The airbag control unit 13505636 controls the restraint system (SRS) in Chevrolet. It processes the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered. It also monitors the system continuously and shows faults via the airbag warning light.

Monitoring also takes place while driving. Every deviation goes into the fault memory so that it can be read out later.

After an accident, the control unit creates crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 13505636 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Aged components, cold solder joints, moisture and corrosion, and voltage spikes can also lead to failure.

A normal diagnostic tool cannot remove crash data. If you send in a unit that holds crash data after an accident, you are therefore dealing with exactly this stored data.

The other causes show up gradually. A connector contact with moisture first causes dropouts, and a voltage spike in the vehicle electrical system can damage components.

How can you tell that the 13505636 is defective?

Typical signs are an airbag warning light that stays on permanently or intermittently, and an error message. In addition, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared.

These points stand out in particular:

• airbag warning light on permanently or intermittently
• error message in the instrument cluster
• diagnostic tool without a connection to the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may fail to trigger. Please have the warning checked promptly.

On the one hand, compare the part number on the label of the removed unit with this page. This only ensures that you have the right unit. On the other hand, have the fault memory read out beforehand; only this result shows whether the control unit is defective or whether a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 13505823, 13580450, 13585613, 13589374, 22483423.
