Airbag control unit with part number 8635A223 DPSB

What does the airbag control unit 8635A223 DPSB do?

The airbag control unit 8635A223 DPSB is the central control unit of the SRS system for Mitsubishi. It checks the signals from the crash sensors continuously and decides in an impact within a few milliseconds whether airbags or seatbelt pretensioners are triggered. It reports any faults via the airbag warning light.

Monitoring runs throughout operation. Deviations are stored in the fault memory so that they can be read out later.

After an accident, it stores crash data and locks itself.

Why does the control unit 8635A223 DPSB fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Crash data arises in an accident, and the control unit keeps it even if no airbag has deployed. It cannot be removed with a normal diagnostic tool. The deletion of the crash data is carried out by Airbag24 during the repair.

Aged electronic components and cold solder joints count among the other causes. Moisture and corrosion at plug connections can likewise trigger faults.

Voltage spikes form a third group: a weak battery or a jump-start can load the vehicle electrical system so that the circuit suffers.

How can you tell that the 8635A223 DPSB is defective?

A defect becomes noticeable when the airbag warning light stays on permanently or intermittently, when the instrument cluster shows a fault message, or when the diagnostic tool cannot connect to the control unit. In an emergency, airbags and seatbelt pretensioners may not trigger.

The airbag warning light in the instrument cluster stays on permanently or intermittently as soon as the control unit holds a fault. It is the most visible sign.

In addition, the instrument cluster may show a fault message. A fault memory that cannot be cleared confirms the suspicion. Have such signs clarified promptly, so that the restraint systems are fully available again.

Which vehicles is the 8635A223 DPSB fitted in?

The control unit 8635A223 DPSB is fitted in these vehicles: Mitsubishi Colt CZ (2004-2008) and CZ Facelift (2008-2012).

The following list names vehicles for this part number:

• Mitsubishi Colt CZ (2004-2008)
• Mitsubishi Colt CZ Facelift (2008-2012)

The label comparison shows whether the removed unit matches this page, but it does not clarify the cause. Therefore have the fault memory read out beforehand. Only the result shows whether the control unit is defective or whether a plug or a cable causes the fault.

For the same vehicles, we also repair control units with the part numbers 285001684, 285001685, 8635A210, 8635A213, 8635A222, 8635A223.

You enclose the log with the unit, disconnect the battery and only then remove the control unit. Afterwards create the repair order and pack the unit carefully.

Airbag24 checks the unit on the test bench, repairs defective components and deletes stored crash data. A function test follows before your own 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 8635A223 DPSB get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. Airbag24 sends it back to you by UPS after the repair.
