B1610
SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: B1610/13: Front Airbag Sensor RH Circuit Malfunction
DTC B1610/13 - Front Airbag Sensor RH Circuit Malfunction
DESCRIPTION
- The front airbag sensor RH consists of the diagnostic circuit, the frontal deceleration sensor, etc.
- If the center airbag sensor receives signals from the frontal deceleration sensor, it determines whether or not the SRS should be activated.
- DTC B1610/13 is recorded when a malfunction is detected in the front airbag sensor RH circuit.
