Mitsubishi Space Runner airbag control unit repair⁽²⁾

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

The Mitsubishi Space Runner airbag control unit evaluates the crash sensors, triggers the airbags and monitors the entire airbag system in the vehicle. If it detects a fault, the airbag warning light in the instrument cluster comes on. After an accident, it stores crash data and locks itself.

A defective control unit can impair the function of the entire airbag system. Typical causes include an accident with deployment, aging electronics, overvoltage from battery problems, moisture on the connectors or communication faults on the CAN bus.

Airbag24 repairs the control unit you send in, which is your own unit. During the repair, crash data is deleted, faults are checked and the unit is then tested. Airbag systems are safety-critical: have any work on the vehicle carried out only by a specialist workshop, and do not work on the airbag system yourself.

Which Mitsubishi Space Runner generations are there?

The Mitsubishi Space Runner was built in two series: N10 from 1991 to 1999 and N50 from 1999 to 2002. The model year of your vehicle usually shows which series it belongs to. The series differ in the control unit part number, so the exact assignment matters for the repair.

• N10 (1991–1999): the first series of the Space Runner
• N50 (1999–2002): the second series with its own part number

The series determines which control unit fits your vehicle. In 1999, when both series are listed, the part number helps. Both series are stored at Airbag24 as separate repair products, so that the correct version can be assigned.

How do I identify my Mitsubishi Space Runner airbag control unit?

The part number on the label of the control unit determines the exact version. For the Space Runner, the part numbers MR141890 (N10) and MR472691 (N50) are on record. Also check the model year and equipment of your vehicle, to avoid mixing up the two series.

For the assignment, the part number, model year and vehicle identification number (VIN) belong together. A clear identification is the basis for every Mitsubishi Space Runner airbag control unit repair.

• MR141890 (N10)
• MR472691 (N50)

This list does not claim to be complete. A fault code in the fault memory is an indication, but on its own it does not prove a defect. Examples from these series are B1498 (internal ROM or RAM fault of the control unit), U0001 (CAN-C bus failed, bus-off) and B1476 (supply voltage IG1 drops below the permitted level).

What airbag equipment does the Mitsubishi Space Runner have?

According to the available information, driver and front passenger airbags are part of the Space Runner's equipment. Whether side airbags are fitted depends on the respective version and is not confirmed for all variants. The actual equipment of your vehicle therefore always remains decisive.

An airbag system consists of the control unit, the crash sensors and the airbag modules, for example for the driver, the front passenger and the sides. The control unit evaluates the sensor signals and decides on deployment in a crash.

For your vehicle, the actual equipment is what counts. The vehicle papers or an equipment list from the production period show which airbags are fitted. Once you know the series and part number, the control unit can be assigned clearly.

The route to repair: first have the fault memory read out. A specialist workshop then disconnects the battery and removes the control unit. Next, create a repair order online and send the unit, well packed, to Airbag24. 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 — no coding or programming is required.
