Airbag control unit with part number 93 162 255 ZW

What does the airbag control unit 93 162 255 ZW do?

The airbag control unit 93 162 255 ZW acts as the central unit controlling the restraint system (SRS) of Opel. Using the signals from the crash sensors, it determines within milliseconds in the event of an accident which airbags and seatbelt pretensioners to trigger, and it monitors the system continuously. It indicates faults via the airbag warning light.

If it stores crash data after an accident, it then locks itself.

Besides the control unit, the restraint system involves sensors, airbags and seatbelt pretensioners. The control unit links them together and is therefore the point where the evaluation is brought together.

Why does the control unit 93 162 255 ZW fail?

The most common cause of a failure of the 93 162 255 ZW is that crash data remains stored after an accident, even if no airbag has been triggered. A standard diagnostic tool cannot erase this data. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, for example from a weak battery or jump-starting.

Whether one of these causes applies in an individual case only becomes clear through a diagnosis. For that reason, it is worth checking the fault memory before the unit is removed.

How can you tell that the 93 162 255 ZW is defective?

A defect in the 93 162 255 ZW shows up in the airbag warning light in the instrument cluster, which lights up either permanently or intermittently, and in a fault message in the instrument cluster. In addition, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

The signs at a glance:

• Airbag warning light in the instrument cluster lights up permanently or intermittently
• Fault message in the instrument cluster
• The diagnostic tool cannot connect to the control unit
• The fault memory cannot be cleared

In that case, the airbags and seatbelt pretensioners may not trigger in an emergency, and a check of the system is advisable.

The warning light alone does not yet show whether the control unit itself is affected.
