Inspection And Verification

WARNING: This page is about a different car, the 2015 Land Rover LR2, 2014 Land Rover LR2, and 2013 Land Rover LR2. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Diagnosis by substitution from a donor vehicle is NOT  acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
  • Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
  1. Verify the customer concern
  2. Visually inspect for obvious signs of damage and system integrity
