When the headlamp switch is turned to the HEAD position, battery voltage is applied to the headlamp opening door actuator control module through CKT 103. The LH head lamp door opens when battery voltage is applied to the LH headlamp opening door assembly through CKT 576 and ground is applied to CKT 577. The RH headlamp door opens when battery voltage is applied to the RH headlamp opening door assembly through CKT 578 and ground is applied to CKT 579.

When the headlamp switch is moved the OFF position, battery voltage is applied to the headlamp opening door actuator control module through CKT 306. The LH headlamp door closes when battery voltage is applied to the LH headlamp opening door assembly through CKT 577 and ground is applied to CKT 576. The RH headlamp door closes when battery voltage is applied to the RH headlamp opening door assembly through CKT 579 and ground is applied to CKT 578.

Battery voltage is constantly applied to the headlamp opening door actuator control module from the HDLP MOT L MiniFuse® #4 (CKT 2940) and from the HDLP MOT R, MiniFuse #3 (CKT 3040). The headlamp opening door actuator control module is grounded by CKT 150 through Splice Pack #100 to G102.
