Description
Airbag control unit for Citroën C1 and Peugeot 107. We do not know the condition of the unit; it is fully functional, it may require clearing of CRASH data.
This airbag (SRS) control module is intended for professional garages and skilled DIY mechanics working on Citroën C1 and Peugeot 107 vehicles. The unit stores crash events and drives the deployment sequence of airbags and seatbelt pretensioners. Many workshops and owners search by the OEM code 89170-0H020, so this listing is optimized to make matching fast and reliable. If the control unit has stored crash memory, a compatible SRS diagnostic tool will be needed to clear fault codes after installation.

Installation recommendations
Only qualified personnel should fit SRS components. Follow these general steps when replacing the unit: disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge; remove trim and seats as required to access the control unit; carefully unplug connectors—do not force or bend pins; install the new unit in the correct orientation and secure mounting fasteners to the factory torque; reconnect connectors and battery. After mechanical fitment, use a compatible SRS diagnostic device to read and clear crash memory and to confirm that there are no active airbag or pretensioner faults.
Why This Part Fails Most Often
The most common reasons for SRS control unit faults are vehicle impact (deployment), water ingress or corrosion affecting connectors or the printed circuit board, electrical shorts from improper repairs, and damage during previous removal or installation. After a deployment event the module normally stores crash data causing the airbag warning light to remain on until the memory is cleared or the module is replaced.
Practical Notes For Buyers
This item is typically searched by part number 89170-0H020. Suitable for Citroën C1 and Peugeot 107; ensure access to an SRS diagnostic tool for clearing crash data and verifying system status after installation. Replacement of related components such as airbags and seatbelt pretensioners may be necessary after a deployment.
