Broadcast Message Originating Module Message Purpose
Illumination Dimming Level   BCM Used to command the illumination intensity for networked modules and outputs that are hard-wired to networked modules.

Networked Illumination Operation

The dimmable switches and components are illuminated when the headlamp switch is in the PARK, ON, or AUTO position. The system-wide illumination intensity is determined by the BCM based on based on inputs from the ambient light sensor and the dimmer switch (iinternal to the headlamp switch).

The BCM sends the dimming level message to the GWM on the HS-CAN1 . The GWM divides the signal between the MS-CAN , HS-CAN2 , and the HS-CAN3 sending messages to the following modules:

The rear door modules receive their dimming level message from the BCM on a LIN connected to the DDM or PDM . The driver side window control switch also uses a LIN to communicate with the DDM .

MS-CAN

  • PDM
  • DDM
  • FCIM

HS-CAN2

  • GSM

HS-CAN3

  • IPC
  • APIM
  • RACM (China only)

If the message is not received, or invalid; a CMDTC is set in the respective module, and the illumination level defaults to full intensity.

The IPC allows a 5 second delay before setting a CMDTC and switching to full intensity. During the 5 second delay, the IPC operates at the illumination intensity last received from the BCM .

Non-Networked Illumination Operation

The BCM calculates the correct intensity for the non-networked illumination sources based on the ambient light intensity input from the light sensor and the requested illumination intensity level input from the dimmer switch. The BCM provides a pulse-width modulated voltage to all non-networked illumination sources.

Field-Effect Transistor (FET) Protection

The BCM is protected by the use of a Field-Effect Transistor (FET) on each output. Refer to the System Diagram to view the different groups of BCM non-networked illumination outputs. For a full description of Field-Effect Transistor (FET) protection,
Refer to: Module Controlled Functions - System Operation and Component Description (419-10 Multifunction Electronic Modules, Description and Operation).

Component Description

Dimmer Switch

The dimmer switch is a 3 position momentary contact switch, integral to the headlamp switch, providing a non-networked input to the BCM . When the dimmer switch is pressed up for increased illumination intensity, and down for decreased illumination intensity, a ground signal received by the BCM on the corresponding terminal is interpreted as a request to increase or decrease illumination intensity.

    Instrument Panel and Interior Switches Illumination - Overview. Description and Operation

    Overview Dimmable illumination provides backlighting to switches and control components when the headlamps or parking lamps are on. The level of intensity is adjusted by pressing the illumination dim up switch up to increase intensity or the dim down switch to decrease intensity...
