Pedestrian Detection System Fault
2016-2016 Subaru Legacy 2.5L H4
The 2016 Subaru Legacy is equipped with a 2.5L flat-4 engine. Below you'll find detailed c0445 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.
Description
Malfunction in the pedestrian detection subsystem of the collision avoidance suite.
Symptoms
- Pedestrian detection warning
- AEB for pedestrians disabled
- Forward camera or radar issue
- Driver assist reduced message
Common Causes
- Camera cannot distinguish pedestrian shapes
- Radar calibration preventing pedestrian classification
- Sensor fusion mismatch
- Software algorithm error
Diagnostic Steps
- Check forward camera operation
- Verify radar module function
- Test in area with pedestrians at low speed
- Check for software updates
- Perform sensor calibration
Repair Notes
Calibrate sensors. Update software if available. Replace faulty camera or radar module.
