Test N: One Turn Signal/Hazard Lamp Is Inoperative/Always On

PINPOINT TEST N: ONE TURN SIGNAL/HAZARD LAMP IS INOPERATIVE/ALWAYS ON

Normal Operation - Fusion
When the smart junction box (SJB) detects the multifunction switch in the LH TURN position, the SJB provides on/off 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 provides on/off voltage through circuit CLS25 (YE/VT) to the RH front turn lamp. Circuits GD123 (BK/GY) and GD121 (BK/YE) provide ground for the LH and RH front turn lamps, respectively. The rear turn lamps are controlled utilizing the rear stoplamp circuitry.

When the SJB detects the multifunction switch in the LH TURN position, the SJB provides on/off 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 provides on/off voltage through circuit CLS25 (YE/VT) to the RH front turn lamp, and through circuit CLS19 (VT/OG) to the RH rear turn lamp. Circuits GD123 (BK/GY) and GD121 (BK/YE) provide ground for the LH and RH front turn lamps, respectively. Circuit GD171 (BK/GY) provides ground for the rear turn lamps.

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