Airbag control unit with part number 38910M68PE0

What does the airbag control unit 38910M68PE0 do?

The airbag control unit 38910M68PE0 is the control unit of the restraint system (SRS) in Suzuki. It processes the signals of the crash sensors, determines in an accident within fractions of a second which airbags and seatbelt pretensioners fire, and checks the system continuously.

In operation it monitors the wiring and the sensor system. If it detects a fault, it stores it and informs the driver via the warning light in the instrument cluster. Without this evaluation there would be no reliable statement about the state of the system.

After an accident the unit stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 38910M68PE0 fail?

Stored crash data after an accident are the most common cause, even when no airbag has fired. An ordinary diagnostic tool cannot erase them. In addition, ageing components, corrosion at plug connections and voltage spikes can lead to failure.

The unit stores the crash data regardless of whether an airbag fired in the emergency. Common diagnostic tools cannot empty this memory. The data remain there until the repair removes them.

Besides the crash data, other circumstances also lead to failure. Electronic components age, solder joints can go cold, and moisture attacks plug connections. Voltage spikes in the vehicle electrical system, for example with a weak battery, also belong to the causes.

How can you tell that the 38910M68PE0 is defective?

The airbag warning light in the instrument cluster lights up permanently or switches on intermittently. Added to this are a fault message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

The warning light is the most important signal for the state of the system. When it is lit, the control unit has detected a fault, and this indication must be taken seriously.

If the diagnostic tool cannot establish a connection with the control unit, that too points to a fault. In an emergency airbags and seatbelt pretensioners may possibly not fire. Therefore have the system checked promptly once the light comes on.

First, compare the part number on the label of the removed unit with this page. This only shows that it is the right unit. Second, have the fault memory read out beforehand. Only this log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 38910M68PD1.

How does the repair of the 38910M68PE0 work?

First read out the fault memory and enclose the log. Only after disconnecting the battery do you remove the unit. Then create the repair order online and send in the well-packed unit.

Airbag24 checks the unit on the test bench, repairs defective components, erases the stored crash data and carries out a function test. Afterwards your own unit goes back to you.

Processing at Airbag24 generally takes 3–4 working days. The time concerns only the checking, repairing and testing in-house.

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 38910M68PE0 get to Airbag24?

Either you pack the unit as a parcel and send it in, or you book a UPS collection for an extra charge. Airbag24 then sends the repaired unit back by UPS.

The printed repair order goes into the parcel. Pack the control unit shock-proof so that it survives transport undamaged.
