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

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

Normal Operation - Explorer, Explorer Sport Trac
When the smart junction box (SJB) detects the multifunction switch in the LH TURN position, the SJB provides 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 voltage through circuit CLS25 (YE/VT) to the RH front turn lamp. Circuits GD120 (BK/GN) and GD123 (BK/GY) provide ground for the LH and RH front turn lamps, respectively. The rear turn lamps are controlled utilizing the rear stoplamp circuits.

When the SJB detects the multifunction switch in the LH TURN position, the SJB provides voltage through circuit CLS21 (BU/GN) to the LH front turn and LH side repeater lamps, 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 voltage through circuit CLS25 (YE/VT) to the RH front turn and RH side repeater lamps, and through circuit CLS19 (VT/OG) to the RH rear turn lamp. Circuits GD120 (BK/GN) and GD123 (BK/GY) provide ground for the LH front turn/side repeater lamps and the RH front turn/side repeater lamps, respectively. Circuits GD149 (BK/GY) and GD151 (BK/GN) provide ground for the LH and RH rear turn lamps, respectively.
