Peugeot 301 I airbag control unit repair

What is a Peugeot 301 I airbag control unit?

The Peugeot 301 I airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors a multitude of sensors, stores relevant crash data, and thus ensures the proper functioning of the entire occupant protection system in the vehicle, which is crucial for safety.

This SRS control unit is specifically designed to monitor and control the airbag and passenger protection system of the Peugeot 301 I. It is crucial for the passive safety of your vehicle.

The module communicates via the vehicle's CAN bus system, receives signals from collision sensors and can trigger an automatic emergency call if necessary.

Why is the Peugeot 301 I airbag control unit defective?

A Peugeot 301 I airbag control unit can fail for a variety of reasons, often due to an accident, water ingress, overvoltage, or internal component failures that lock the module and necessitate repair. Such a failure will cause the airbag warning light in the instrument cluster to activate and significantly compromise vehicle safety, making immediate Peugeot 301 I airbag control unit repair essential.

After an accident, airbag control units store crash data and are often locked, even if no physical damage is visible. This lock prevents them from being used again without a special repair.

Water damage or electrical surges can permanently damage the control unit's sensitive electronics, which can lead to malfunctions or complete failure.

Even without external influence, internal defects in components or software can occur that impair the function of the airbag system and require diagnosis.

Common error codes for Peugeot 301 I airbag control unit repair

During Peugeot 301 I airbag control unit repairs, specific error codes are often read out, indicating internal defects, communication problems, or voltage issues. These diagnostic codes are crucial for precisely identifying the cause of the fault and enabling targeted repair of the failure to fully reactivate the airbag system.

The codes below are typical for airbag control unit/ECU fault diagnostics on Peugeot vehicles, which can also occur on the 301 I.

• B1000 → Control unit communication error → Problems in the data transmission to the control unit.
• 293 9602 → Driver airbag error → Inconsistency in the configuration of the driver airbag.
• 305 960E → Passenger knee airbag error → Configuration problem with the passenger knee airbag.
• 306 9610 → Front left satellite error → Front left impact sensor coherence error.
• 314 9650 → Supply voltage error → Inconsistency of the vehicle electrical system voltage to the airbag control unit.
• 316 9660 → Passenger airbag deactivation switch error → Inconsistency in the passenger airbag deactivation switch.
• B1111 → Control unit defective → Internal hardware or software error in the airbag control unit.

What part numbers are available for the Peugeot 301 I airbag control unit repair?

For Peugeot 301 I airbag control unit repairs, precise identification of the part number is crucial, but specific OEM numbers for this model are often difficult to verify. Since airbag control units are coded for specific vehicles, a VIN-based query at a Peugeot dealer or specialized service center is essential to ensure compatibility for a successful repair and avoid incorrect purchases.

Direct and fully verified OEM part numbers for the Peugeot 301 I airbag control unit are difficult to find in general sources.

Examples of numbers from other Peugeot models that have not been verified for the Peugeot 301 I are 6547WJ or 6556N9 (Peugeot 206) and 821641 (Peugeot 306).

The code 98 056 301 80 620 59 52 00 is mentioned in connection with Peugeot 301, but appears to be a service or reset reference rather than an OEM part number for the control unit.

To determine the correct part number for your Peugeot 301 I airbag control unit repair, you should request the vehicle identification number (VIN) from a Peugeot dealer.

Manufacturers such as Bosch, Continental or Autoliv supply the control units, but their specific numbers for the Peugeot 301 I must be determined through official channels.
