Mazda CX-5 Service & Repair Manual: Front Fog Light

Purpose

• By shining light in a wider area in front of the vehicle than the light from the headlights, visibility during poor weather conditions, such as rain and fog, has been improved. In addition, the visibility of the vehicle from on-coming vehicles, pedestrians, and other people has been improved.

Function

• Illuminates according to the light switch and front fog light switch operation.

Construction

• Round-type fog lights are installed to the front bumper.

• Clear lenses have been adopted to the front fog lights.

Operation

1. With the light switch in the TNS, HEAD, or HI position, a front fog light switch signal is sent to the start stop unit when the front fog light switch is operated to the on position.

2. The start stop unit sends the front fog light switch signal to the front body control module (FBCM).

3. When the front body control module (FBCM) receives the fog light switch signal, it turns the front fog light relay on.

4. When the front fog light relay turns on, the front fog light bulb illuminates.
