System Diagram
System Description
OUTLINE
BCM reads the status of the combination switch (light, turn
signal, wiper and washer) and recognizes the status of each switch.
BCM has a combination of 5 output terminals (OUTPUT 1 - 5) and 5
input terminals (INPUT 1 - 5) and reads a maximum ...
P0101 MAF sensor
Description
The mass air flow sensor (1) is placed in the stream of intake air. It
measures the intake flow rate by measuring a part of the entire
intake flow. The mass air flow sensor controls the temperature of the
hot wire to a certain amount. The heat generated by the hot wire is ...
