Airbag control unit with part number 65777911608

What does the airbag control unit 65777911608 do?

The airbag control unit 65777911608 controls the airbags and seatbelt pretensioners as the restraint system (SRS) in Rolls-Royce. The crash sensors supply it with measurements, from which it derives the trigger within milliseconds. After an accident it stores crash data and locks itself.

In operation it checks its connections and circuits continuously. If it detects a fault, the fault is stored in the fault memory.

The airbag warning light informs the driver about the condition of the system.

Why does the control unit 65777911608 fail?

Stored crash data is the most common cause with the 65777911608, even if no airbag has been triggered; a normal diagnostic tool does not erase it. Besides this, there are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as those from a weak battery or jump-starting.

The crash data is held in the control unit itself, not in the belts or sensors.

A plug with moisture or corrosion can trigger messages similar to an internal problem.

How can you tell that the 65777911608 is defective?

A defect in the 65777911608 is indicated by the airbag warning light in the instrument cluster, which may light up permanently or intermittently. Further signs are a fault message in the instrument cluster, a diagnostic tool without connection to the control unit and a fault memory that cannot be cleared.

• Airbag warning light permanently or intermittently on
• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

With such a finding, the airbags and seatbelt pretensioners may not be able to deploy in an emergency. The next step is therefore to have the system checked.
