Airbag control unit with part number 38910M68PC0

What does the airbag control unit 38910M68PC0 do?

The 38910M68PC0 is the central control unit of the restraint system (SRS) for Suzuki vehicles. It evaluates the signals from the crash sensors and decides which airbags and seatbelt pretensioners are triggered in an accident.

The evaluation takes place within milliseconds, so the unit must react without delay. In addition it monitors the entire system continuously and shows faults via the airbag warning light in the instrument cluster.

After an accident the control unit creates crash data and then locks itself. The driver notices nothing of this in everyday driving.

Why does the control unit 38910M68PC0 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be removed with a standard diagnostic tool, and that is precisely why the fault remains in the fault memory. The other causes work more gradually: ageing components lose reliability over time, and cold solder joints can interrupt the contact inside the unit.

Moisture and corrosion mainly attack the plug connections, while voltage spikes arise, for example, from a weak battery or a jump start. Which cause applies in the individual case only becomes clear when the fault memory is read out.

How can you tell that the 38910M68PC0 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition there is a fault message in the instrument cluster, a missing connection to the diagnostic tool, and a fault memory that cannot be cleared.

A diagnostic tool that cannot establish a connection to the control unit indicates that communication within the system is disturbed. If the light comes on only briefly, the cause should still be clarified.

In an emergency the airbags and seatbelt pretensioners may then not deploy. The warning light indicates the finding, and you should take this notice seriously.

Which vehicles is the 38910M68PC0 fitted in?

First check whether your vehicle belongs to this assignment. The 38910M68PC0 is fitted in these vehicles: Suzuki Baleno WB (2015-2022) and WB Facelift (from 2022).

The following overview shows the vehicles for which this control unit is listed:

• Suzuki Baleno WB (2015-2022)
• Suzuki Baleno WB Facelift (from 2022)

Compare the part number on the label of the removed unit with this page. That only ensures that it is the right unit. Also have the fault memory read out beforehand, because only this record 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 38910M68PC0 work?

First have the fault memory read out and enclose the log. Then disconnect the battery, and only afterwards remove the control unit and create a repair order online. Pack the unit well and send it in. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 checks the unit on the test bench, replaces defective components and clears the stored crash data. A function test follows.

Afterwards your own control unit is returned to you.

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 38910M68PC0 get to Airbag24?

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

Put the printed repair order into the parcel and pack the unit shock-proof.
