  1. A1 CHECK THE HIGH BEAM OPERATION 
    • Key in OFF position.
    • Place the headlamp switch in the HEADLAMPS ON position.
    • Place the multifunction switch to the HIGH BEAM position.
    • Do the high beams illuminate? 
    1. YES  : Go to Pinpoint Test B .
    2. NO  : Go to  A2.
  2. A2 CHECK CIRCUIT 196 (DB/OG) FOR AN OPEN 
    • Place the headlamp switch in the OFF position.
