DTC P1613 Secondary Air Injection Driver Malfunction
DESCRIPTION
Refer to DTC P0412 ().
| DTC No. | DTC Detection Condition | Trouble Area |
| P1613 | Either condition (1) or (2) is met: (1) All conditions are met for 3 seconds or more (1 trip detection logic): Either the air pump or the emission control valve is not operating. Diagnostic signal from the air injection control driver is 80%. Battery voltage is 8 V or higher. Battery voltage is 8 V or higher. Diagnostic signal from the air injection control driver is abnormal (duty signal other than 0, 20, 40, 80 or 100%). | Air injection control driver assembly Open in air injection control driver ground circuit |
All conditions are met for 3 seconds or more (1 trip detection logic): Air injection system is operating (the emission control valve and air pump are on). Diagnostic signal from the air injection control driver is 0%. Battery voltage is 8 V or higher. | Short in diagnostic information signal circuit (Air injection control driver - ECM) Open or short in air pump and emission control valve command signal circuit (Air injection control driver - ECM) Open in air injection control driver ground circuit Air injection control driver assembly ECM | |
Both conditions are met for 3 seconds or more (1 trip detection logic): Battery voltage is 8 V or higher. Diagnostic signal from the air injection control driver is 100%. | Open or short in air injection control driver +B circuit Open in diagnostic information signal circuit (Air injection control driver - ECM) Air injection control driver assembly ECM |
MONITOR DESCRIPTION
This DTC indicates an open or short circuit in the circuit containing the air pump of the secondary air injection system. The air injection control driver performs diagnosis of the air pump assembly, emission control valve set and itself, and sends the results of this diagnosis to the ECM as a duty signal. When the ECM receives a signal indicating a malfunction in the air pump assembly, emission control valve set or air injection control driver assembly, it immediately illuminates the MIL and stores a DTC.

INSPECTION PROCEDURE
- HINT:
| 1.CHECK AIR INJECTION CONTROL DRIVER ASSEMBLY (POWER SOURCE CIRCUIT) |
Disconnect the air injection control driver assembly connector.
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Switch Condition Specified Condition C61-5 (+B) - Body ground Ignition switch ON 11 to 14 V (near battery voltage)
| *a | Front view of wire harness connector (to Air Injection Control Driver Assembly) |
|
| ||||
| OK | |
| 2.CHECK HARNESS AND CONNECTOR (AIR INJECTION CONTROL DRIVER ASSEMBLY - ECM, BODY GROUND) |
Disconnect the ECM connector.
Disconnect the air injection control driver assembly connector.
Measure the resistance according to the value(s) in the table below.

Measure the voltage between the SIV and E terminals of the ECM connector when the secondary air injection system is ON and OFF.
Turn the ignition switch off.
- NOTICE:
- Standard Voltage:
Tester Connection Condition Specified Condition C61-3 (SIV) - C61-1 (E) AIR PUMP: ON, ASV: OPEN 0.5 to 2 V C61-3 (SIV) - C61-1 (E) AIR PUMP: OFF, ASV: CLOSE 11 to 14 V
Connect terminals DI and SIP of the wire harness connector for the air injection control driver assembly.
| *1 | Air Injection Control Driver Assembly |
| *2 | ECM |
| *a | Front view of wire harness connector (to Air Injection Control Driver Assembly) |
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Utility / Secondary Air Injection Check / Manual Mode / AIR PUMP: ON, ASV 1: OPEN, ASV 2: OPEN.
- HINT:
