| CHECK HARNESS BETWEEN FUSE BOX AND SECONDARY AIR COMBINATION VALVE. |
|
1) Remove the secondary air combination valve fuse (10 A) from the fuse box. 2) Disconnect connectors from the secondary air combination valves (LH and RH). 3) Measure the resistance between the secondary air combination valve fuse and secondary air combination valve connector terminals, and chassis ground. Connector & terminal (F9) No. 2 — Chassis ground: (E41) No. 4 — Chassis ground: (E40) No. 1 — Chassis ground: |
| QUESTION | |
|
Is the resistance more than 1 MΩ? | |
| Yes | No |
|
Replace the fuse with a new part, and then connect the secondary air combination valve connector.
