Taillamp Circuit

Taillight Circuit

DESCRIPTION
Front light:
The front controller controls the operation of the FR TAIL relay. The FR TAIL relay turns on the front side marker lights and parking lights.

The front controller receives front side marker and parking light ON request signals from the combination switch ECU through BEAN communication and activates the FR TAIL relay.

The FR TAIL relay is built into the front controller, so unlike conventional relays, it cannot be removed for inspection.

Rear light:
The main body ECU RH controls the operation of the TAIL relay. The TAIL relay turns on the taillights, license plate lights, and side marker lights.

The main body ECU RH receives taillight, license plate light, and side marker light ON request signals from the combination switch ECU through BEAN communication and activates the TAIL relay.

The TAIL relay is built into the cowl side J/B LH, so unlike conventional relays, it cannot be removed for inspection.
