DTC B2445

id080200807400

System Malfunction Location

• Passenger-side side air bag sensor (internal circuit abnormal)

Detection Condition

Warning
• Detection conditions are for understanding the DTC outline before performing an inspection. Performing an inspection according to only the detection conditions may cause injury due to an operating error, or damage the system. When performing an inspection, always follow the inspection procedure.

• The passenger-side side air bag sensor monitors the scale of an impact. If the crash event is severe enough for the passenger-side side air bag module to operate (deploy), the sensor will signal the SAS control module to operate (deploy) the passenger-side side air bag. The SAS control module monitors signals which are not within the specification to the passenger-side side air bag sensor. If the SAS control module receives a signal from the passenger-side side air bag sensor which indicates improper installation of the sensor, it will store DTC B2445 in memory and output a pattern 49 flash to the air bag system warning light.

Possible Cause

• Driver-side side air bag sensor damage
