Headlight (Hi-Beam) Circuit

Headlight (HI-BEAM) Circuit

DESCRIPTION

When either of the following conditions is met, the high beam headlights come on.
- Dimmer switch in HIGH position and light control switch in HEAD position.
- Dimmer switch in HIGH position, light control switch in AUTO position, and low beam headlights are on.

HINT:
- The power distributor has a fail-safe function control. If a short circuit occurs between the power distributor and high beam headlight bulb, the power distributor stops the DRL relay operation.
- The DRL relay is built into the power distributor, so unlike conventional relays, it cannot be removed for inspection.
- If only a high beam headlight on one side does not illuminate, inspect the fuse, bulb, or wire harness that is related to the bulb.
- If both right and left high beam headlights do not illuminate, read the dimmer switch HIGH signal value in the data list, and perform the DRL relay active test to determine if the malfunction exists on either the switch side or the relay side.
