Normal Operation - Fusion
When the smart junction box (SJB) detects the multifunction switch in the LH TURN position, the SJB sends voltage through circuit CLS21 (BU/GN) to the LH front turn lamp. When the SJB detects the multifunction switch in the RH TURN position, the SJB sends voltage through circuit CLS25 (YE/VT) to the RH front turn lamp. Circuit GD123 (BK/YE) and circuit GD121 (BK/RD) provide ground for the LH and RH front turn lamps, respectively. The rear turn lamps are controlled utilizing the rear stoplamp circuits.

Normal Operation - Milan
When the SJB detects the multifunction switch in the LH TURN position, the SJB sends voltage through circuit CLS21 (BU/GN) to the LH front turn lamp, and through circuit CLS18 (GY/BN) to the LH rear turn lamp. When the SJB detects the multifunction switch in the RH TURN position, the SJB sends voltage through circuit CLS25 (YE/VT) to the RH front turn lamp, and through circuit CLS19 (VT/OG) to the RH rear turn lamp. Circuit GD123 (BK/YE) and circuit GD121 (BK/RD) provide ground for the LH and RH front turn lamps, respectively. Circuit GD171 (BK/GY) provides ground for the rear turn lamps.

Normal Operation - Zephyr
When the SJB detects the multifunction switch in the LH TURN position, the SJB sends voltage through circuit CLS21 (BU/GN) to the LH front turn lamp, and through circuit CLS18 (GY/BN) to the LH rear turn lamp. When the SJB detects the multifunction switch in the RH TURN position, the SJB sends voltage through circuit CLS25 (YE/VT) to the RH front turn lamp, and through circuit CLS19 (VT/OG) to the RH rear turn lamp. Circuit GD123 (BK/YE) and circuit GD121 (BK/GY) provide ground for the LH and RH front turn lamps, respectively. Circuit GD171 (BK/GY) provides ground for the rear turn lamps.

On vehicles equipped with daytime running lamps (DRL), the front turn lamps are utilized as the DRL.
