DESCRIPTION
The AID drives the ASV and the air pump according to command signals transmitted by the ECM. The pressure
sensor detects the pressure in the secondary air passage when the AIR system is ON and OFF, and transmits a
pressure signal to the ECM.
The AID is not only equipped to drive the pump and valve, but also with a diagnosis function to detect
malfunctions in the AIR system circuit.
HINT:
As a large current is required to drive the air pump and ASV, an AID is installed to this system.
