Airbag control unit with part number 8635A093L

What does the airbag control unit 8635A093L do?

The airbag control unit 8635A093L coordinates the restraint system (SRS) for Mitsubishi. In the event of a crash, it checks the signals from the crash sensors and determines which airbags and seatbelt pretensioners are triggered.

The decision is made within milliseconds, and the system is monitored continuously. The unit reports detected faults to the airbag warning light.

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

Why does the control unit 8635A093L fail?

On the 8635A093L, stored crash data after an accident is the most common cause, even if no airbag has deployed. Other causes include ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be erased with an ordinary diagnostic tool. Airbag24 removes it during the repair, so this point is cleared up.

Voltage spikes occur, for example, with a weak battery or when jump-starting. The electronics can be damaged as a result, and plug connections exposed to moisture are particularly vulnerable.

How can you tell that the 8635A093L is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. The instrument cluster also shows an error message, and the diagnostic tool cannot reach the 8635A093L.

In addition, there is a fault memory that cannot be erased. The warning light therefore shows the fault immediately.

In the event of a defect, airbags and seatbelt pretensioners may not trigger when needed. It is therefore wise not to ignore the warning.

Which vehicles is the 8635A093L fitted in?

The 8635A093L is fitted in these vehicles: Mitsubishi Pajero V90 (2007-2012) and V90 Facelift (2012-2021). Use these details to compare your vehicle with the unit.

The assignment looks like this:

• Mitsubishi Pajero V90 (2007-2012)
• Mitsubishi Pajero V90 Facelift (2012-2021)

Comparing the part number on the label of the removed unit with this page only confirms the identity of the unit. Only a read-out fault memory shows 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 153000313, 3SR791, 5757A026, 7407A095, 7420A082, 8635A457.

How does the repair of the 8635A093L work?

First have the fault memory read out and attach the log, then disconnect the battery and remove the control unit 8635A093L. Afterwards, create the repair order online, and the well-packed unit goes to Airbag24. As a rule, 3–4 working days pass at Airbag24 for inspection, repair and testing.

At Airbag24, the unit is checked, defective components are replaced, the crash data is erased and a function test is carried out. You then receive your own unit back.

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 8635A093L get to Airbag24?

You send the control unit 8635A093L as a parcel or opt for a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS.

Pack the printed repair order into the parcel and protect the unit against impact.
