| CHECK HARNESS BETWEEN SECONDARY AIR COMBINATION VALVE RELAY CONNECTOR AND SECONDARY AIR COMBINATION VALVE CONNECTOR. |
|
1) Remove the secondary air combination valve relay from the relay box. 2) Measure resistance between the secondary air combination valve relay and secondary air combination valve connector. Connector & terminal (F9) No. 3 — (E40) No. 6: (F9) No. 3 — (E4) No. 2: |
| QUESTION | |
|
Is the resistance less than 1 Ω? | |
| Yes | No |
|
|
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit in harness between the secondary air combination valve relay and secondary air combination valve connector • Poor contact of coupling connector |
