DESCRIPTION

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.

HINT:
·

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.
