Airbag control unit with part number MR587758

What does the airbag control unit MR587758 do?

The airbag control unit MR587758 controls the restraint system (SRS) of Mitsubishi. It evaluates the crash sensors and, in a crash, decides within milliseconds which airbags and seatbelt pretensioners are triggered. After an accident it locks itself.

During operation it monitors all triggers and sensors. If it detects a fault, it displays this via the airbag warning light in the instrument cluster. In addition, the manufacturer number Bosch 0285001687 is printed on the housing.

Why does the control unit MR587758 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. It cannot be removed with a standard diagnostic tool. Ageing components, cold solder joints, moisture, corrosion and voltage spikes are also possible causes.

Crash data arises after an accident and remains in the unit until it is removed during the repair. Whether the airbags fired makes no difference to this.

How can you tell that the MR587758 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message also appears in the instrument cluster. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

Signs of a defect at a glance:

• airbag warning light on permanently or intermittently
• error message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be cleared

With these signs, airbags and seatbelt pretensioners may not trigger in an emergency.

Compare the part number on the label of the removed unit with this page. This only ensures that it is the correct unit. Whether the control unit itself is defective or a plug or cable is the cause only becomes clear from reading out the fault memory beforehand.

For the same vehicles, we also repair control units with the part numbers 285001684, 8201A143, 8635A223, 97RA-0104822, MR587416, MR587417.

How does the repair of the MR587758 work?

You first read out the fault memory, enclose the log, disconnect the battery and then remove the control unit. Next you create a repair order online and send in the carefully packed unit. Airbag24 checks the unit, replaces defective components, erases the crash data and performs a function test; processing there takes 3–4 working days as a rule.

At Airbag24 the unit first goes through the check on the test bench. Afterwards your own unit is returned 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 MR587758 get to Airbag24?

You send the unit in as a parcel or book a UPS collection for an extra charge. The printed repair order goes into the parcel, and the unit is packed shock-proof. After the repair, Airbag24 sends it back by UPS.

Filling material in the packaging prevents the unit from moving inside the carton.
