Code B1347 Lincoln Description

When the rear defrosts switch on the climate control assembly is pressed, a ground signal is sent to the Smart Junction Box (SJB) on the circuit. The SJB then grounds circuit. This energizes the heated rear window relay, allowing voltage to be supplied to the heated rear window grid through the circuit. The OBDII code sets when the Heated Backlite Input is not to factory specifications.
