What is a Jaguar XK8 X100 airbag control unit?
The Jaguar XK8 X100 airbag control unit, also known as the Restraint Control Module (RCM), is the central component of the passive safety system. It continuously monitors sensors, detects impacts, and precisely deploys airbags and seatbelt pretensioners to provide optimal occupant protection.
It is crucial for the functionality of the SRS (Supplemental Restraint System) in your Jaguar XK8 X100. The module stores important data and ensures the full operational readiness of all restraint systems.
Why is the Jaguar XK8 X100 airbag control unit defective?
A Jaguar XK8 X100 airbag control unit often fails because it stores crash data after an accident, preventing a reset, or because internal electronics fail over time. This results in a permanently illuminated airbag warning light and deactivation of the safety system.
Other typical causes of failure include water ingress or overvoltage in the vehicle electrical system, which can damage the sensitive electronics. Such a failure requires immediate professional diagnosis and repair of the Jaguar XK8 X100 airbag control unit.
Common error codes for Jaguar XK8 X100 airbag control unit repair
When repairing a Jaguar XK8 X100 airbag control unit, specific error codes are crucial for identifying the exact cause of a problem. These messages, readable as B-codes or blink codes, directly indicate problems in the control unit or its circuitry.
- B1000 → Control unit communication error → Signal interruption or internal defect in the RCM.
- 13 → Crash data full → Control unit has saved trigger data after accident.
- 18 → Airbag deactivation indicator error → Problem with the airbag status indicator.
- 19 → Driver side airbag circuit fault → Short circuit or open circuit in the driver circuit.
