Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on.
5.
Wait 16 seconds or more.
6.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
7.
Read the pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
8.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
9.
Input the DTC: P1607.
10.
Check the DTC judgment result.

HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
11.
If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and
check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE
NOTICE:
After turning ignition switch off, waiting time may be required before disconnecting the cable from the
negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative
(-) battery terminal notices before proceeding with work
.
HINT:
Read freeze frame data using a Techstream. Freeze frame data record the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other
data from the time the malfunction occurred.

MONITOR DESCRIPTION
For a short time after a cold engine start, the ECM transmits command signals to the Air Injection Control Driver
(AID) to drive the air pump and the Air Switching Valve (ASV). The AID detects open and short circuits according
If the Secondary Air Injection (AIR) system circuit or the AID itself malfunctions, the AID sends a malfunction
signal (duty signal) as diagnostic information to the ECM (when the system is normal, a system normal signal is
sent). The ECM stores the DTC based on the diagnostic information from the AID.
EXAMPLE:
1.
2.
The AID outputs the normal signal (normal duty signal: 80%) while the system is not operating.
