Airbag control unit with part number MR587417 DPSB

What does the airbag control unit MR587417 DPSB do?

The airbag control unit MR587417 DPSB controls the restraint system (SRS) of Mitsubishi. It processes signals from the crash sensors, determines in a crash which airbags and seatbelt pretensioners are triggered, and checks the system continuously.

If a fault is detected, the unit shows it via the airbag warning light. This light sits in the instrument cluster and is the most important warning on the vehicle for you.

After an accident, the unit stores crash data and locks itself.

Why does the control unit MR587417 DPSB fail?

The most common cause is crash data stored in the unit after an accident, even if no airbag has deployed. Other causes include aged electronic components, cold solder joints, moisture at plug connections and voltage spikes.

A normal diagnostic tool cannot erase the crash data, but Airbag24 deletes it during the repair.

The remaining causes lie in the ageing of electronic components, in cold solder joints, or in moisture and corrosion at plug connections. Voltage spikes, for example from a weak battery or a jump start, can also damage a unit. Only an examination can establish which cause applies.

How can you tell that the MR587417 DPSB is defective?

A defect becomes visible when the airbag warning light in the instrument cluster lights up permanently or intermittently. Fault messages in the instrument cluster, a lost connection to the diagnostic tool and a fault memory that cannot be cleared are also conspicuous.

Typical signs are:

• Airbag warning light that stays on permanently
• Airbag warning light that only lights up intermittently
• Fault message in the instrument cluster
• No contact between the diagnostic tool and the control unit

In this state, airbags and seatbelt pretensioners may fail to deploy in an emergency. A prompt check is therefore advisable.

Compare the part number on the label of the removed unit with this page; this only confirms that it is the right unit. Also have the fault memory read out beforehand, because only this result shows whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285001684, 285001685, 8635A210, 8635A213, 8635A222, 8635A223.

How does the repair of the MR587417 DPSB work?

Have the fault memory read out first and attach the log. Then disconnect the battery and only afterwards remove the control unit. Next, create a repair order online and send the unit in well packed; processing at Airbag24 usually takes 3–4 working days.

This sequence serves safety and must be followed. Airbag24 checks the unit on the test bench, repairs defective components, deletes stored crash data and carries out a function test.

Your own unit is then sent 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 MR587417 DPSB get to Airbag24?
