• Ignition off
• Light switch in position 0
• Disconnect connector A to the left-hand gas discharge lamp module (GDL).

  Check the connectors for contact resistance and oxidation. Check for damage carefully.

  Check the signal cable between the central electronic module (CEM) and the left-hand gas discharge lamp module (GDL). Check for an open-circuit. Check for a short-circuit to ground.

  Take readings between:

  • Central electronic module (CEM) terminal #E29 (#29) and left-hand gas discharge lamp module (GDL) terminal #A6.

  Check that the left-hand gas discharge lamp module (GDL) is connected to ground.

  Take readings between:

  • Left-hand gas discharge lamp module (GDL) terminal #A10 and ground.

  Remedy as necessary.
