Airbag control unit with part number 0 285 010 206

What is the function of Airbag Control Unit 0 285 010 206?

The Bosch Airbag Control Unit 0 285 010 206 is the central control module for the passive safety system in the Land Rover Freelander 2. It processes data from crash sensors and is responsible for precisely triggering airbags and seatbelt pretensioners within seconds in the event of a collision.

As an SRS module (Supplemental Restraint System), it continuously monitors all connected components, such as impact sensors, seat occupancy mats, and the ignition pyrotechnic devices of individual airbags. Its task is to analyze the type and severity of a collision and, based on this analysis, activate the appropriate restraint systems.

This control unit is also known under alternative part numbers 6H52-14B321-AE, 044A74A/B/C/D, or 9H52-14D374-AD, which are installed in the same vehicle models and perform the same function.

Why does Control Unit 0 285 010 206 fail?

The most common cause of failure for Control Unit 0 285 010 206 is stored crash data after an accident, which prevents further use. Other causes include internal electronic component defects leading to complete communication failure, as well as aging or moisture damage.

After a collision, the unit permanently stores crash data in its internal memory. This is a manufacturer‑imposed safety measure that cannot be reset using standard diagnostic tools. As a result, the control unit becomes electronically locked, even if there is no physical damage.

Another frequent issue is total loss of communication: the control unit no longer responds to requests from a diagnostic tool. Common causes include defective components on the circuit board—such as capacitors or sensors—that have been damaged by vibration, aging, or ingress of moisture.

Error codes stored in the fault memory, such as 00003, or indications of an “accident memory,” are clear signs of a defect requiring specialized repair.

How do you recognize a defect in Control Unit 0 285 010 206?

The most obvious symptom of a faulty Airbag Control Unit 0 285 010 206 is the constantly illuminated airbag or SRS warning light on the instrument cluster. Often, a workshop will also be unable to establish communication with the control unit to read out the fault memory.

The airbag warning light fails to turn off after starting the vehicle, signaling a serious malfunction in the safety system that compromises the functionality of airbags and seatbelt pretensioners.

Another clear indication is when the diagnostic tool reports that communication with the SRS module is impossible. In this case, the control unit is effectively “dead” electronically and must be repaired.

Even if communication is possible, persistent error codes indicating stored crash data or an internal control unit fault directly point to a module defect.

Important: Before removal, a qualified workshop should read out the fault memory to confirm that the root cause is indeed the control unit itself, rather than a faulty sensor or incorrect wiring.

In which vehicles is Control Unit 0 285 010 206 installed?

The Airbag Control Unit with part number 0 285 010 206 was specifically developed by Bosch for the Land Rover Freelander 2. It is used across the entire model range from 2006 to 2014, including both facelifted versions.

At Airbag24, we repair this control unit for the following specific models:

Land Rover Freelander 2 (model years 2006–2010)

Land Rover Freelander 2 First Facelift (model years 2010–2012)

Land Rover Freelander 2 Second Facelift (model years 2012–2014)

The repair service also covers units bearing alternative designations 6H52-14B321-AE, 044A74A/B/C/D, and 9H52-14D374-AD, which are installed in the aforementioned vehicles.

How is Control Unit 0 285 010 206 repaired?

Professional repair at Airbag24 involves electronic refurbishment without replacing the unit. Upon receipt, our technicians analyze the root cause of the fault, reset stored crash data, replace defective components, and finally conduct a functional test.

First, the control unit is removed from the vehicle—typically located beneath one of the front seats. You then ship it securely packaged, ideally with a printout of the fault log, to us.

Upon arrival at Airbag24, the unit undergoes a thorough incoming inspection. Our technicians identify the exact source of the problem, whether it’s purely a data issue or a hardware defect.

Repair is performed at the component level. Stored crash data is completely and safely erased using specialized software. Defective components on the circuit board are expertly replaced, restoring the unit to its original condition.

After successful repair and a final quality inspection, the control unit is fully functional and ready for installation. We provide 2 years' statutory liability for defects on every repair.
