BMW X5: Butt Connector For Repairing A Plug Connection
Special tools required:
IMPORTANT:
- Identify cause of damage (e.g. sharp-edged body parts, faulty
electrical
loads, jammed mechanisms, corrosion caused by ingress of water, etc.).
- Read out fault memory.
- Eliminate cause of damage.
- Disconnect battery negative terminal.
- Make sure that no safety-related system according to connection
scheme
(e.g. anti-lock braking system, active rear-axle kinematics, airbags, etc.)
are influenced. Otherwise replace faulty wiring harness or use repair
cable (sourcing reference: BMW Parts Service).
- Carry out function test and read out fault memories again.
- Eliminate new faults if applicable and clear fault memories
NOTE: The repair range IV for vehicle electrical system contained the
required special
tools and individual parts for retrofitting and repair work with the aid of fan
connectors.
The case can no longer be ordered. Order individual parts for wiring harness
repair through BMW Parts Service.
