What is a Rover Freelander Serengeti airbag control unit?
The Rover Freelander Serengeti airbag control unit is your vehicle's central safety unit, deploying all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores important crash data, and ensures the proper functioning of all connected components, essential for safety in the Rover Freelander Serengeti.
This module is responsible for precisely controlling airbag deployment in the event of an impact. It continuously communicates with the vehicle's bus system to monitor all safety components.
Integrated acceleration sensors detect the severity of the accident, while the evaluation electronics diagnose pyrotechnic elements and wiring harnesses. This ensures a fast and reliable system response.
Why is the Rover Freelander Serengeti airbag control unit defective?
A defective Rover Freelander Serengeti airbag control unit is often the result of accident damage, aging electronics, or voltage spikes that cause internal errors. A Rover Freelander Serengeti airbag control unit repair is necessary if the SRS system reports malfunctions or no longer communicates at all.
Because crash data is stored in the control unit after an accident, a malfunction or blockage can occur. This prevents further use of the module without a specialized reset service.
Age-related material fatigue or corrosion on the internal circuit boards can also lead to failures. Such damage often manifests itself in sporadic warning lights or a lack of system communication.
Electrical problems such as low voltage or short circuits can damage the sensitive electronics of the airbag control unit. This requires a detailed diagnosis at a specialist workshop for your Rover Freelander Serengeti airbag control unit repair.
Common error codes for Rover Freelander Serengeti airbag control unit repair
Rover Freelander Serengeti airbag control unit repairs typically display generic OBD-II B codes, as manufacturer-specific trouble codes are rarely publicly available. These codes indicate internal ECU errors, communication problems, or power supply malfunctions that require specific diagnostics.
- B1000 → Control unit communication error → Faulty connection to the vehicle bus.
- B0100 → Airbag control unit error → Internal error in the airbag control unit.
- B1001 → Configuration error → Incorrect or corrupted software configuration.
- B1207 → Airbag control unit flash EEPROM error → Error in the internal memory of the control unit.
- B1241 → Airbag control unit voltage supply too low → Undersupply or voltage fluctuations.
- B1400 → Airbag control unit internal error → Critical internal defect of the ECU.
What part numbers are available for the Rover Freelander Serengeti airbag control unit repair?
There are several verified OEM and supplier part numbers available for the Rover Freelander Serengeti airbag control unit repair, which vary by model year and generation. It is crucial to verify the exact part number of your original control unit to ensure proper function and compatibility.
The Land Rover OEM number DH5214D374AA is closely related to the Bosch part number 0285011177. These have been verified for the Freelander SRS control unit and are often used interchangeably.
Older Freelander models of the L314 series often use the Land Rover Genuine Parts YWC000340, YWC105790, or YWC106360. These are listed and confirmed in various independent spare parts databases.
For the newer Freelander 2 (L359), the Land Rover part number 6H52-14B321-AE and the corresponding Bosch part number 0285010206 are relevant. Precise identification is essential for a successful Rover Freelander Serengeti airbag control unit repair.
A comparison with the chassis number of your Rover Freelander Serengeti is always recommended. This minimizes the risk of incompatibilities and ensures functionality after replacement or repair.
