Headlamps (Export)

The headlamps are turned on when the driver places the headlamp switch in the HEADLAMP position. The LIGHTING 40 A fuse in the underhood fuse/relay center supplies battery positive voltage to the headlamp switch.

The headlamp switch signal circuit supplies voltage to the headlamp dimmer switch when the headlamp switch is in the PARK or ON position. Depending on the position of the headlamp dimmer switch, voltage is supplied either to the headlamp high beam supply voltage circuit or the headlamp low beam supply voltage circuit. Voltage is then supplied to the RH or LH 10 A fuses in the underhood fuse/relay center and to the respective headlamp. The headlamps are grounded at G108 and G109.
