High Beam Indicator Test
- Check high beam headlight operation. If high beams do not operate, headlight diagnosis is necessary. If high beams are okay, enter BCM diagnosis input BI79 and operate headlight dimmer switch. See BCM DIAGNOSIS PROCEDURE .
- With headlight dimmer switch pulled toward steering wheel and held, display should indicate LO. With dimmer switch released, display should indicate HI.
- If displays are correct and high beam indicator still does not operate, replace BCM. If the displays are incorrect, additional BCM diagnosis is necessary.
