Mitsubishi L400 airbag control unit repair⁽¹⁾

What should I pay attention to with Mitsubishi L400 airbag control units?

The airbag control unit in the Mitsubishi L400 evaluates the crash sensors, monitors the airbag system and reports faults via the airbag warning light. After an accident, it stores crash data and locks itself. Because the airbag system is safety-relevant, its repair belongs in the hands of a specialist workshop.

In an accident, the control unit triggers the airbags and, where fitted, the belt tensioners. If the airbag warning light comes on, this points to a fault in the system. A defective control unit can, in an emergency, prevent the airbag system from working as intended.

Airbag24 repairs your own airbag control unit that you send in, at our workshop in Berlin. This includes checking for faults and erasing the crash data.

Which Mitsubishi L400 generations are there?

In our overview, the Mitsubishi L400 is listed as one series: Space Gear, built from 1994 to 2005. The construction period is the first point of reference for classifying a vehicle.

Within this period, control units can differ in design depending on model year and equipment. The model alone is not enough for classification. The part number of the installed control unit is therefore the decisive factor.

• Space Gear (1994–2005) – the series of the Mitsubishi L400; model year and part number determine the exact design.

How do I identify my Mitsubishi L400 airbag control unit?

The part number on the label of the control unit determines its exact design. Also check the model year and equipment of your vehicle.

The part number is therefore the most important point of reference for identification. Examples of part numbers (not a complete list):

• MR277718
• MR277719

Fault codes can help narrow things down, for example B1498 (ROM or RAM fault in the control unit) or B1699 (collective deployment detected). A single code does not, however, prove a defect; its evaluation belongs with a specialist workshop.

Which airbag equipment does the Mitsubishi L400 have?

The airbag equipment of the Mitsubishi L400 depends on model year, market and trim level. Check which airbags are actually fitted in your vehicle.

Whether a particular example has front airbags for driver and front passenger, or side or head airbags, cannot be stated in general terms. The control unit always coordinates only the airbags actually fitted in the respective vehicle.

The route to the Mitsubishi L400 airbag control unit repair works as follows: the battery is disconnected, the fault memory is read out and the control unit is removed. Because the airbag system is safety-relevant, a specialist workshop should carry this out. You then create a repair order online and send the removed control unit to Airbag24, well packed. Processing usually takes 3–4 working days (checking, repairing, testing).

The repaired control unit comes back with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not necessary.
