Airbag control unit with part number 25348 6GA0A

What does the airbag control unit 25348 6GA0A do?

The airbag control unit 25348 6GA0A is the central control unit of the restraint system (SRS) in Nissan. It evaluates the signals from the crash sensors, decides in a crash within fractions of a second which airbags and seatbelt pretensioners are triggered, and monitors the system without interruption. It shows faults via the airbag warning light in the instrument cluster.

In a crash, the unit writes crash data and then locks itself.

Because the entire triggering depends on this unit, any irregularity in the restraint system must be taken seriously.

Why does the control unit 25348 6GA0A fail?

Stored crash data is the most common cause, even if no airbag triggered after the accident; a normal diagnostic tool cannot remove it. Ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes are also possible causes.

The unit creates the crash data as soon as it has processed an accident. Whether an airbag triggered in the end makes no difference to that.

Electronics age over the years. Solder joints on the circuit board can become cold or brittle, and moisture promotes corrosion on connectors, which disturbs the contact.

Voltage spikes occur, for example, with a weak battery or when a jump start is given. Checking the vehicle electrical system is therefore part of finding the cause.

How can you tell that the 25348 6GA0A is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool cannot establish a connection to the control unit, or the fault memory cannot be cleared. The airbags and seatbelt pretensioners may then possibly not trigger in an emergency.

These signs occur individually or together:

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool with no connection to the control unit
• Fault memory cannot be cleared

A lit warning light should be checked in any case, even if the vehicle can still be driven.

Which vehicles is the 25348 6GA0A fitted in?

The control unit 25348 6GA0A is fitted in these vehicles: Nissan 370Z Z34 Facelift (2013-2020) and Z34 (2008-2013).

These vehicles are recorded in our data for this part number:

• Nissan 370Z Z34 Facelift (2013-2020)
• Nissan 370Z Z34 (2008-2013)

Two steps help you here. First, compare the part number on the label of the removed unit with this page; that confirms you have the right unit. Then have the fault memory read out beforehand, because only that shows whether the control unit is defective or a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 25348 1A33B, 98820 1EJ1A, 98820-1EA0A, 98820-1ER0A, K8820-1EA0A, K8820-1EJ0A.

How does the repair of the 25348 6GA0A work?

First have the fault memory read out and attach the log, then disconnect the battery before you remove the control unit. Afterwards you create the repair order online and send the unit in well packed. Airbag24 examines it on the test bench, repairs defective components, erases stored crash data and carries out a function test, after which your own unit is sent back to you.

This order must be followed for safety reasons, because the restraint system is affected by the removal.

Processing at Airbag24 usually takes 3–4 working days. This time covers only the testing, repair and function test carried out there.

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 25348 6GA0A get to Airbag24?

You send the unit as a parcel, or you book a UPS collection for an extra charge. Airbag24 returns the unit by UPS after the repair.

Pack the printed repair order into the parcel and pack the unit shockproof.
