Airbag control unit with part number 601958200

What does the airbag control unit 601958200 do?

The airbag control unit 601958200 is the central control unit of the restraint system (SRS) for Peugeot. It evaluates the signals from the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. Detected faults are displayed via the airbag warning light.

The monitoring runs in the background during the entire journey. The unit checks sensors, wiring and control circuits and records every irregularity in memory, so that the display in the instrument cluster remains reliable.

After an accident the control unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 601958200 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start.

Electronics that have been working in the vehicle for a long time show weak points over time. Whether the control unit itself is affected cannot be determined reliably from the fault pattern alone.

Airbag24 deletes the stored crash data during the repair. This deletion is therefore part of the repair process and is not something you have to carry out yourself.

How can you tell that the 601958200 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

As long as the warning light reports irregularities, airbags and seatbelt pretensioners may not trigger in an emergency. This notice should therefore be taken seriously and checked promptly.

Compare the part number on the label of the removed unit with this page. That only ensures you have the correct unit in front of you. Also have the fault memory read out beforehand, because only the log shows whether the control unit itself is the cause or a plug or cable is.

For the same vehicles, we also repair control units with the part numbers 9635784280, 9640722980, 9644903280, 9645840780, 9650109480, 9652013880.

How does the repair of the 601958200 work?

First have the fault memory read out and attach the log to the unit. Then disconnect the battery, only then remove the control unit, and create a repair order online. Afterwards send the well-packed unit in; Airbag24 examines and repairs it and returns your own unit.

The order of these steps is fixed for safety reasons. The battery must not remain disconnected before removal, and the readout must come first.

Airbag24 examines the unit on the test bench, replaces defective components, deletes stored crash data and carries out a function test. Processing at Airbag24 usually takes 3–4 working days. 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 601958200 get to Airbag24?

You send the unit as a package or book a UPS collection for an extra charge. After the repair Airbag24 returns it to you by UPS.

Place the printed repair order in the package and pack the control unit shock-resistant.
