This DTC is stored when the combination meter assembly detects an open in a front turn signal light circuit or rear turn signal light circuit.
If there is an open in a front turn signal light circuit or rear turn signal light circuit, the turn signal lights on the side with the open circuit will blink faster than usual.
If there is an open in a side turn signal light circuit, DTC B150718 will not be stored.
