DESCRIPTION
The front airbag sensor LH consists of the diagnostic circuit and frontal deceleration sensor, etc.
If the center airbag sensor receives signals from the frontal deceleration sensor, it determines whether the SRS should be activated.
DTC B1615/14 is stored when a malfunction is detected in the front airbag sensor LH circuit.
