MAIN BODY Tester Display Test Part Control Range Diagnostic Note Head Light Hi High beam headlights ON/OFF - OK High beam headlights illuminate. NG --> See step 3 OK --> See step 8
  3. CHECK HARNESS AND CONNECTOR (SHORT IN RELAY-DRIVEN CIRCUIT) HINT: When a short circuit occurs between the power distributor (engine room junction block assembly) and high beam headlight bulb, a fail-safe function operates to stop high beam headlight operation. Remove the H-LP RH HI fuse from the power distributor (engine room junction block assembly). Turn the light control switch to the head position and turn the dimmer switch to the high position. Check if the high beam headlight LH illuminates. Turn the dimmer switch to the low position. Install the H-LP RH HI fuse and remove the H-LP LH HI fuse. Turn the dimmer switch to the high position. Check if the high beam headlight RH illuminates. OK Either high beam headlight LH or RH illuminates. NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
