Airbag control unit with part number MN141446

What does the airbag control unit MN141446 do?

The airbag control unit MN141446 is the central control unit of the restraint system (SRS) for Mitsubishi. In a collision, it decides which airbags and seatbelt pretensioners are triggered, within a fraction of a second.

At the same time, it monitors the system continuously. It shows detected faults via the airbag warning light in the instrument cluster.

If the control unit stores crash data after an accident, it locks itself. A repair is the only way to lift this lock.

Why does the control unit MN141446 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Other possible causes include ageing components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Crash data cannot be erased with a standard diagnostic tool. The repair at Airbag24 removes it.

Electronic components are subject to wear. Solder joints can go cold, and moisture or corrosion on plug connectors impairs the contact.

Voltage spikes occur, for example, with a weak battery or during a jump start, and can damage components.

How can you tell that the MN141446 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, together with an error message. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

• The airbag warning light stays on.
• The light keeps flickering on.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot reach the control unit.
• The fault memory remains even after clearing.

With such signs, airbags and seatbelt pretensioners may not trigger in an emergency. The warning signal should therefore be taken seriously.

A fault does not stay hidden, because the warning light shows it. Do not ignore the display, but have the system checked.
