Control Module

The first step for removing the headlamp control module requires removal of the passenger side front floor kick up panel cover to reach the instrument panel electrical center where you can extract the headlamp circuit breaker. Open the hood and use the manual headlamp motor control to turn the knob counterclockwise for helping with raising the right headlamp. Knight the rh headlamp wiring harness electrical connector from the forward lamp wiring harness while supporting the vehicle. First disconnect the front fascia lower closeout panel and separate the brake caliper cooling duct from the fascia before moving it to the correct location. First disconnect the electrical connectors attached to the headlamp control module before removing the nuts from the bracket of the headlamp and extracting the module from the vehicle. After placing the headlamp control module onto the bracket you need to mount it using installation nuts. Connect electrical module connectors after which install the brake caliper cooling duct to the front fascia before securing it with pushing motion. The technician must first install the front fascia lower closeout panel then manually lower the vehicle before reconnecting the rh headlamp wiring harness electrical connector to the forward lamp wiring harness. Use the headlamp motor/actuator manual control knob to rotate clockwise in order to manually lower the rh headlamp. After placing the headlamp circuit breaker in the electrical center you should install floor kick up panel over the ip electrical center then complete the process by closing the hood.

The first step to replace the headlamp control module requires removal of the passenger side front floor kick up panel cover for access to the instrument panel (IP) electrical center followed by extracting the headlamp circuit breaker from the center. Head to the hood to operate the rh headlamp manually by turning the headlamp motor/actuator manual control knob towards the opposite direction. This will help you lift the headlamp into position. First disconnect the wiring harness electrical connector from the forward lamp wiring harness and then raise your vehicle while supporting it safely. The first task involves taking off the front fascia lower closeout panel followed by detaching the brake caliper cooling duct from the front fascia before setting it aside. The first step requires disconnecting power connectors from the headlamp control module before removing its mounting nuts for bracket removal. The new headlamp control module requires mounting on the headlamp bracket followed by fastening it with mounting nuts. The electrical connectors need reattachment to the module before reinstalling the brake caliper cooling duct into its position on the front fascia and applying force to secure it. After installing the front fascia lower panel attach the vehicle to the ground while reconnecting the headlamp wiring harness of the right side to the forward lamp wiring harness. To manually lower the rh headlamp users should turn the headlamp motor/actuator manual control knob to the clockwise direction. Instillation of the headlamp circuit breaker in the ip electrical center completes the process as the floor kick up panel covers the ip electrical center and the hood closes.

Position the headlamp control module onto the headlamp bracket and secure it with the nuts.

Disconnect the electrical connectors from the headlamp control module, then remove the nuts that mount the module to the headlamp bracket and take the module out of the vehicle.
