DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK CURRENT DATA.
NOTE:
For detailed operation procedures, refer to "READ CURRENT DATA FOR ENGINE". <Ref. to
SUBARU SELECT MONITOR .>
|
Is the value of «Sec. Air Piping Pressure» 133.3 kPa (1, 000 mmHg, 39.4 inHg) or more? | Go to step 2 . | Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
NOTE:
In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
|
2 CHECK HARNESS BETWEEN ECM AND SECONDARY AIR COMBINATION VALVE CONNECTOR.
NOTE:
For detailed operation procedures, refer to "READ CURRENT DATA FOR ENGINE". <Ref. to
SUBARU SELECT MONITOR .>
|
Is the value of «Sec. Air Piping Pressure» 133.3 kPa (1, 000 mmHg, 39.4 inHg) or more? | Repair the short circuit to power in harness between ECM connector and secondary air combination valve LH connector. | Go to step 3. |
3 CHECK HARNESS BETWEEN ECM AND SECONDARY AIR COMBINATION VALVE CONNECTOR.
|
Is the resistance less than 5 Ω? | Go to step 4 . | Repair the harness and connector.
NOTE:
In this case, repair the following item:
|
| 4 CHECK FOR POOR CONTACT. Check for poor contact of the secondary air combination valve LH connector. |
Is there poor contact of the secondary air combination valve LH connector? | Repair the poor contact of the secondary air combination valve LH connector. | Replace the secondary air combination valve LH. <Ref. to SECONDARY AIR COMBINATION VALVE .> |
