Airbag control unit with part number 898156441Y

What does the airbag control unit 898156441Y do?

The airbag control unit 898156441Y is the central control unit of the restraint system (SRS) for Isuzu. It evaluates the signals from the crash sensors, decides in an accident within milliseconds on the triggering of the airbags and seatbelt pretensioners, and monitors the system continuously.

The unit reports faults via the airbag warning light in the instrument cluster. This keeps the restraint system in view at all times, even when nothing stands out in everyday driving.

After an accident it stores crash data and locks itself.

Why does the control unit 898156441Y fail?

The most common cause is stored crash data after an accident, even without a triggered airbag. Also aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

A usual diagnostic scanner does not remove this data. At Airbag24 it is removed as part of the repair.

For the other causes, age and environment play a role. Solder joints can break, plug contacts corrode, and voltage spikes attack the electronics.

How can you tell that the 898156441Y is defective?

Typical signs are the airbag warning light, an error message in the instrument cluster, missing contact with the diagnostic tool and a fault memory that cannot be cleared.

• Airbag warning light stays on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool gets no connection to the control unit
• Fault memory cannot be cleared

If one of these findings is present, the airbags and seatbelt pretensioners may not deploy in an emergency. A prompt check is therefore sensible.

Comparing the part number on the label of the removed unit with this page ensures that you have the right unit. It does not clarify the cause, though. For that, the fault memory must be read out before removal, because only then does it show whether the control unit is defective or whether a connector or cable is affected.

For the same vehicles, we also repair control units with the part numbers 898146938Y, 898159361Y.

How does the repair of the 898156441Y work?

First have the fault memory read out, then disconnect the battery and only then remove the control unit. Next, create the repair order online. At Airbag24, testing, repair and checking usually take 3–4 working days.

Airbag24 examines the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. The unit of your own is then sent back to you.

The well-packed control unit is sent in after the repair order has been created. The process serves safety; that is why the unit is never removed before the battery has been disconnected.

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.

Shock-proof means firm material, sufficient padding and a carton that completely encloses the unit.
