Roof Control Module
The Roof Control Module (RCM) (also known as the Overhead Control Panel/OCP control unit or DBE) is integral to the optional OCP (1) located on the headliner between the front driver and passenger seats just behind the upper windshield opening header. The OCP is available in multiple configurations, which vary from vehicle to vehicle depending upon the optional equipment in the vehicle. Besides the RCM, the OCP may include the following features:
- Automatic Interior Lighting and Reading Lamp Switches (2)
- Eyeglasses Storage Compartment or optional Vehicle Theft Security System (VTSS) Front Interior Motion Sensor and Inclination Sensor (4) - motion/inclination sensor includes Interior Protection OFF and Tow-Away Protection OFF Switches.
- Front Dome and Reading Lamp Lenses (3)
- Hands-Free Microphone for Telephone (6)
- Power Sliding Sunroof Switch (5)
The RCM and OCP housings, the lamp lenses and the push buttons are constructed of molded plastic. Each push button has a smooth finish and is clearly identified with the appropriate text or International Control and Display Symbol icons. Several of the push buttons feature Light Emitting Diode (LED) units to provide panel lamps dimmer controlled back lighting for visibility at night, but these LED units are integral to the circuit board within the RCM and are not serviceable.
Eight screws secure the RCM to the back of the OCP housing, while the OCP is secured above the headliner by two engagement tabs and two spring clips. The back of the RCM housing has an integral connector receptacle containing terminal pins that connect the unit to the vehicle electrical system through a dedicated take out and connector of the vehicle wire harness.
The individual switches in the RCM cannot be repaired and are not serviced individually. The incandescent bulbs for the dome and reading lamps are available for individual service replacement. If any other component within the RCM is ineffective or damaged, the RCM unit must be replaced.
