Airbag control unit with part number GK62-14D374-AA

What does the airbag control unit GK62-14D374-AA do?

The control unit GK62-14D374-AA evaluates the sensor data at Land Rover and forms the central authority of the restraint system (SRS). In an emergency it decides within fractions of a second on the triggering of airbags and seatbelt pretensioners and reports faults to the airbag warning light. After an accident it stores crash data and locks itself.

The evaluation runs in the background during operation, and the system is monitored without interruption.

This includes the wiring, the sensors and the control of the seatbelt pretensioners.

Why does the control unit GK62-14D374-AA fail?

The most common cause is stored crash data after an accident, even without a triggered airbag; a normal diagnostic tool cannot erase it. Further causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

• Ageing of components on the circuit board
• Cold solder joints
• Wet conditions and corrosion in the plugs
• Voltage spikes from a weak battery or a jump start

Airbag24 erases the crash data during the repair.

How can you tell that the GK62-14D374-AA is defective?

The airbag warning light lights up permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool makes no contact with the control unit and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then not deploy in an emergency.

The light is therefore a clear reason for a check.
