  6. H6 CHECK FOR CORRECT HUD (HEAD UP DISPLAY) OPERATION

    • Ignition OFF.

    • Disconnect and inspect HUD module connector and related in-line connectors.

    • Repair:

      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
