PINPOINT TEST B: ONE LOW BEAM HEADLAMP IS INOPERATIVE

Normal Operation
When the smart junction box (SJB) detects the headlamp switch in the HEADLAMPS ON position and the multifunction switch in the LOW BEAM position, the SJB provides voltage through circuits CLF04 (BN/BU) and CLF05 (BU/GN) to the LH and RH low beam headlamps, respectively. Ground is supplied through circuits GD120 (BK/GN) and GD164 (BK/VT) to the LH and RH low beam headlamps, respectively.
