Lada Kalina 1117/1118/1119 airbag control unit repair

What is a Lada Kalina 1117/1118/1119 airbag control unit?

In the Lada Kalina 1117/1118/1119, the airbag control unit is the central control unit of the restraint system (SRS). It reads out the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners deploy, and indicates faults via the airbag warning light.

This unit is fitted in the 2004 to 2013 model series. The vehicle's sensors constantly supply measured values, and the control unit evaluates them immediately. Only when the deployment criteria are met does it switch the appropriate firing circuits.

It stays in service even without an accident: The control unit continuously checks the restraint system and makes every detected fault visible via the warning light in the instrument cluster.

After an accident, the control unit stores crash data and locks itself. Only a repair makes it ready for use again.

Why is the Lada Kalina 1117/1118/1119 airbag control unit defective?

You will usually notice the airbag warning light first, staying on permanently. The most common cause behind it is an accident whose crash data is stored in the control unit, even if no airbag deployed; an ordinary diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion on connectors, or voltage spikes.

A second sign: You read out the fault memory, clear the entries, and the message returns. Or the diagnostic tool finds no contact with the control unit at all. Both suggest that the unit itself has a problem.

Behind such symptoms there are often quite everyday causes. A jump start or a weak battery produces voltage spikes that put stress on sensitive circuits. Over the years components age, and solder joints crack through temperature changes. If moisture reaches the connectors, the contacts corrode and fault messages appear.

Common error codes for Lada Kalina 1117/1118/1119 airbag control unit repair

Which error codes a Lada Kalina 1117/1118/1119 reports is determined by the manufacturer, and you read them out of the fault memory with a diagnostic tool. The codes point to the area of the fault, such as communication, internal control unit faults, a firing circuit or stored crash data.

How the entries read depends on the equipment and the diagnostic tool. Print or save the read-out log, and enclose it with the unit when you send it in. That way the troubleshooting during the inspection can be more targeted.

Bear in mind: A single code does not prove a defect in the control unit. Connectors, wiring or an airbag module are equally possible. Which part is affected only becomes clear during the inspection.

What part numbers are available for the Lada Kalina 1117/1118/1119 airbag control unit repair?

You will find the part number on the label on the housing of the control unit, and it determines the exact version. Depending on equipment and year of manufacture, the numbers within a model series differ.

For the Lada Kalina 1117/1118/1119, the following numbers are known; this list is not complete.

• 1118-3824010
• 605048100C

Hold the number of your own unit next to this list. The comparison merely confirms that you have the right unit in your hands. Whether a defect exists is only shown by reading out the fault memory or by the inspection at Airbag24.

The way to the repair looks like this: Have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send the unit to us. Inspecting, repairing and testing usually take 3–4 working days at Airbag24. Your own unit is repaired, and it comes back to you.

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.
