PINPOINT TEST 3: ONE TURN SIGNAL/HAZARD LAMP IS INOPERATIVE/ALWAYS ON
Normal Operation
When the smart junction box (SJB) detects the multifunction switch in the LH TURN position, the SJB provides voltage through circuit (L/G) to the LH
front turn lamp. When the SJB detects the multifunction switch in the RH TURN position, the SJB provides voltage through circuit (Y/V) to the RH
front turn lamp. Circuit (B/G) provides ground. The rear turn lamps are controlled utilizing the rear stoplamp circuitry.
-
