Airbag control unit with part number DK62-14D374-AG

What does the airbag control unit DK62-14D374-AG do?

The airbag control unit DK62-14D374-AG brings together all decisions of the restraint system (SRS) in Land Rover. It evaluates the signals from the crash sensors and determines in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

The unit checks the system for plausibility continuously. If it reports a fault, this appears on the airbag warning light in the instrument cluster, through which the driver recognises the condition of the system.

Triggering is bound to fixed evaluation rules. Which components come into use depends on the direction and severity of the impact, and the control unit itself makes this assessment.

Why does the control unit DK62-14D374-AG fail?

Crash data from an accident that remains in memory is the most common cause, even if no airbag has deployed. An ordinary diagnostic tool does not remove it. Aged components, cold solder joints, moisture, corrosion at plugs and voltage spikes are also involved.

Crash data is created during the impact and then stays in the unit. Whether an airbag or seatbelt pretensioner has triggered is irrelevant to this entry.

The remaining sources of fault lie in the electronics and in the connection to the vehicle electrical system. Components age, solder joints can become cold, and moisture alters the contacts. Voltage spikes, for example from a weak battery or a jump start, load the electronics.

How can you tell that the DK62-14D374-AG is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. This is accompanied by a fault message in the instrument cluster; in addition the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared.

The warning light shows that the control unit has detected a fault in the restraint system. In everyday use it is therefore the most important sign that the driver notices.

When the light appears, airbags and seatbelt pretensioners may fail to trigger in an emergency. A missing connection to the diagnostic tool also prevents the fault memory from being read, and then the cause remains open until an examination takes place.

Which vehicles is the DK62-14D374-AG fitted in?

The airbag control unit DK62-14D374-AG is fitted in these vehicles: Land Rover Range Rover Evoque L538 (2011-2015) and L538 Facelift (2015-2018).

The list of vehicles for this part number follows.

• Land Rover Range Rover Evoque L538 (2011-2015)
• Land Rover Range Rover Evoque L538 Facelift (2015-2018)

These steps help in advance. Comparing the part number on the label of the unit with this page only confirms that it is the right unit. Having the fault memory read beforehand shows, by contrast, whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers GJ32-14D374-AB, GJ32-14D374-AC, LR032045, LR139699.

How does the repair of the DK62-14D374-AG work?

First have the fault memory read and enclose the log with the unit. Then disconnect the battery and only afterwards remove the control unit. Finally, create a repair order online and send the unit.

Airbag24 examines the unit on the test bench, repairs defective components and deletes stored crash data. A function test follows, after which the unit is returned to you. Processing at Airbag24 usually takes 3–4 working days.

Our repairs come with 2 years' statutory liability for defects.

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.

How does the control unit DK62-14D374-AG get to Airbag24?

The control unit goes to Airbag24 either as a parcel, or you book a UPS pickup for an extra charge. After the repair, UPS brings the unit back to you.

The repair order, printed out, goes into the parcel. Pack the unit shock-resistant.
