The rear combination lights are used to signal the following conditions to vehicles/people at the rear.
Rear turn lights: Signals a left or right turn of the vehicle.
Brake lights: Signals a vehicle stop.
Taillights: Signals the presence of the vehicle to vehicles/people at the rear during nighttime.
Rear side marker lights: Signals the presence of the vehicle to vehicles/people at the adjacent rear during nighttime.
The related light turns on or flashes according to the operation of each switch.
| Operation switch | Related light | Operation condition |
| Light switch (TNS) | Taillight | Turns on |
| Rear side marker light | Turns on |
|
| Brake switch | Brake light | Turns on |
| Turn switch | Rear turn light | Flashes |
| Hazard warning switch |
The following parts are an integrated structure.
Rear turn light
Brake/taillight
Rear side marker light
The brake/taillight has adopted a LED.
A clear lens has been adopted for the rear combination light.
NOTE:
Fogging or condensation on the inside of the rear combination lights may occur, however, it is a natural phenomenon occurring as a result of a temperature difference between the interior and exterior of the combination lights and has no effect on the light performance. Fogging or condensation will dissipate when the temperature inside the rear combination lights rises after the rear turn light bulbs are illuminated and a period of time has elapsed.
1. When the light switch is operated to the TNS position, a light switch TNS signal is input to the start stop unit.
2. The start stop unit sends the light switch TNS signal to the front body control module (FBCM).
3. When the front body control module (FBCM) receives the light switch TNS signal, it turns the TNS relay on.
4. When the TNS relay turns on, the taillights are illuminated.
Operation due to brake pedal operation
Without Mazda Radar Cruise Control (MRCC) system
When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
When the brake switch (No.1 signal) turns on, current flows from the battery to the brake lights.
The brake lights turn on.
With Mazda Radar Cruise Control (MRCC) system
When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
When the brake switch (No.1 signal) turns on, a brake switch (No.1 signal) on signal is input to the brake light unit.
When the brake light unit receives a brake switch (No.1 signal) on signal, it supplies current to the brake lights.
The brake lights turn on.
Operation due to operation request signal from rear body control module (RBCM)
NOTE:
Refer to "SMART CITY BRAKE SUPPORT (SCBS)" and "MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM]" for details.
Without Mazda Radar Cruise Control (MRCC) system
When the operation conditions are met, the rear body control module (RBCM) turns on the transistor inside the rear body control module (RBCM).
When the transistor inside the rear body control module (RBCM) turns on, the brake light relay turns on.
When the brake light relay turns on, current flows from the battery to the brake lights.
The brake lights turn on.
With Mazda Radar Cruise Control (MRCC) system
When the operation conditions are met, the rear body control module (RBCM) turns on the transistor inside the rear body control module (RBCM).
When the transistor inside the rear body control module (RBCM) turns on, the transistor inside the brake light unit turns on.
When the transistor inside the brake light unit turns on, current flows to the brake lights.
The brake lights turn on.
1. When the turn switch is operated to the LH position, a turn switch LH signal is input to the start stop unit.
2. When the turn switch is operated to the RH position, a turn switch RH signal is input to the start stop unit.
3. The start stop unit sends the turn switch LH or RH signal to the front body control module (FBCM).
4. When the front body control module (FBCM) receives the turn switch LH signal, the rear turn light (LH) flashes.
5. When the front body control module (FBCM) receives the turn switch RH signal, the rear turn light (RH) flashes.
1. When the hazard warning switch is turned on, a hazard warning signal is input to the start stop unit.
2. The start stop unit sends a hazard warning signal to the front body control module (FBCM).
3. When the front body control module (FBCM) receives the hazard warning signal, the rear turn light (LH) and (RH) flash.
1. When the light switch is operated to the TNS position, a light switch TNS signal is input to the start stop unit.
2. The start stop unit sends the light switch TNS signal to the front body control module (FBCM).
3. When the front body control module (FBCM) receives the light switch TNS signal, it turns the TNS relay on.
4. When the TNS relay turns on, the rear side marker lights are illuminated.
