Airbag control unit with part number MN141500

What does the airbag control unit MN141500 do?

The airbag control unit MN141500 is the central control unit for the restraint system (SRS) at Mitsubishi. It evaluates crash sensors, decides in an accident whether airbags and seatbelt pretensioners fire, and monitors the system continuously. After an accident it stores crash data and locks itself.

The evaluation takes place within milliseconds and exclusively in the control unit.

The unit reports faults in the system via the airbag warning light in the instrument cluster. In this way the driver learns that the restraint system needs checking.

Why does the control unit MN141500 fail?

The most common cause is stored crash data, which remains in the unit after an accident even if no airbag has deployed. It cannot be erased with a normal diagnostic tool; Airbag24 erases it during the repair. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

An accident without a deployed airbag looks unremarkable in hindsight, but the data remains in memory. In the event of a failure it is therefore worth considering an earlier incident.

Voltage spikes arise, for example, from a weak battery or when a jump-start is connected. Moisture and corrosion on the contacts are another typical reason for failures.

How can you tell that the MN141500 is defective?

A defect shows on the airbag warning light in the instrument cluster, which lights continuously or intermittently, as well as an error message in the instrument cluster. In addition the diagnostic tool does not find the control unit, and the fault memory cannot be cleared.

As long as these signs persist, airbags and seatbelt pretensioners may not deploy in an emergency. Therefore do not wait for the problem to resolve itself.

The warning light indicates the defect, so it does not remain hidden. The cause is only determined by checking the fault memory.

Which vehicles is the MN141500 fitted in?

This part number is in use at Mitsubishi. The control unit MN141500 is fitted in these vehicles: Mitsubishi Outlander CU (2001-2006).

The vehicles in detail:

• Mitsubishi Outlander CU (2001-2006)

Compare the part number on the label of the removed unit with this page. This only confirms that you have the correct unit in front of you. Also have the fault memory read out before removal, because only the log 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 MR587732, MR587868, W2T61972.

How does the repair of the MN141500 work?

Have the fault memory read out and the log attached, then disconnect the battery and only then remove the control unit. Afterwards create a repair order online and send the unit well packed. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Afterwards your own unit is returned to you.

The 3–4 working days apply only to checking, repairing and testing at Airbag24. Reading out, removal and shipping do not fall under them.

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 MN141500 get to Airbag24?

The unit goes to Airbag24 as a parcel, or you book a UPS collection for an extra charge. After the repair Airbag24 sends it back to you by UPS.

Put the printed repair order in the box and pack the control unit shock-proof.
