Airbag control unit with part number MN141448

What does the airbag control unit MN141448 do?

The airbag control unit MN141448 is the central control unit of the SRS in Mitsubishi. In a crash it evaluates the crash sensors, decides within milliseconds on the deployment of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

Faults that the control unit detects are reported via the airbag warning light in the instrument cluster. In this way the driver learns that something is wrong with the restraint system.

Why does the control unit MN141448 fail?

The most common cause is crash data stored after an accident, even when no airbag has deployed. They cannot be erased with a normal diagnostic tool. Other causes are ageing of the electronics, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data remain stored in the unit after an accident, even if no airbag has opened. Reading out with a normal diagnostic tool changes nothing about this.

The other causes concern electronics and contacts. Aged components and cold solder joints can fail, and moisture and corrosion impair the contact at plug connections.

Voltage spikes, for example from a weak battery or a jump start, put additional strain on the electronics. At Airbag24, stored crash data are erased during the repair.

How can you tell that the MN141448 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. The diagnostic tool does not find the control unit, and the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may not be able to deploy.

A fault may occur only intermittently. If the light goes out again, that is no reason to leave the system unchecked.

Have the system checked promptly before you rely on its function.

Which vehicles is the MN141448 fitted in?

The MN141448 is fitted in these vehicles: Mitsubishi Outlander CU (2001-2006). The part number determines this assignment.

The list of assigned models follows:

• Mitsubishi Outlander CU (2001-2006)

These points matter before you send the unit in. Compare the part number on the label of the removed unit with this page to make sure it is the correct unit. Also have the fault memory read out beforehand, because only that result shows whether the control unit itself is at fault 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 MN141448 work?

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

The order must be kept for safety reasons. This applies to reading out, disconnecting and removal alike.

Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a functional test. The unit then goes back 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 MN141448 get to Airbag24?

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

Enclose the printed repair order and pack the control unit shock-proof.
