Circuit Breaker (Built Into BCM)
For example, when current is 30A, the circuit is broken within 8 to 20 seconds.This circuit breaker is used for the following systems:
Power windows
Power moonroof
Power seat
Power lumbar
Power sunshade
Circuit Breaker (External to BCM)
The PTC thermistor generates heat in response to current flow...
