Outline
The discharge headlight system utilizes a gas discharge type light to emit a white light resembling sunlight over a wide area. Also, use of the gas discharge type light realizes high efficiency, low power consumption lighting.

System Wiring Diagram
Operation
1. When the light switch is operated to the HEAD position, a light switch LO signal is input to the start stop unit.
2. The start stop unit sends the light switch LO signal to the front body control module (FBCM) as a CAN signal.
3. When the front body control module (FBCM) receives the light switch LO signal, it turns the headlight LO relay on.
4. When the headlight LO relay turns on, the igniter raises the DC voltage from the battery to approx. 25,000 V and outputs it to the discharge headlight bulb so that the xenon gas emits light.
5. When the discharge headlight bulb (xenon gas) emits light, the discharge headlight control module converts the DC voltage from the battery to AC voltage (approx. 42 V) and outputs it to the discharge headlight bulb to illuminate the bulb.
PCM Configuration (Using As Built Data)
NOTE:
If the configuration is performed using As-Built data, the set value of the
personalization function is reset to the initial value (condition when shipped
from factory). Verify the set value with the customer and perform the personalization
function setting after performing th ...
Odometer/Tripmeter
Purpose
The odometer/tripmeter notifies the user of the total travel distance or
the traveled distance over a specific interval.
Function
The instrument cluster calculates the traveled distance based on the traveled
distance signal from the PCM and displays it.

WARNING
Do not replace the xenon fusion bulbs yourself:
Replacing the xenon fusion bulbs yourself is dangerous. Because the xenon fusion
bulbs require high voltage, you could receive an electric shock if the bulbs are
handled incorrectly. Consult an Authorized Mazda Dealer when the replaceme ...
