For a short time after cold engine starts, the ECM transmits command signals to the AID to drive the air pump
and ASV.
signals from the ECM to drive the air pump.
The voltage at the AID terminal relating to the air pump is high despite the AID receiving no
command signals from the ECM to drive the air pump.
The ECM sets the DTC based on diagnostic signals from the AID.
