CHECK HARNESS BETWEEN FUSE BOX AND SECONDARY AIR PUMP.

1) Remove the secondary air pump fuse from the fuse box.

2) Disconnect the secondary air pump connector.

3) Measure the resistance between the secondary air pump fuse and secondary air pump connector, and chassis ground.

Connector & terminal

(F9) No. 16 — Chassis ground:

(F11) No. 2 — Chassis ground:

QUESTION

Is the resistance 1 MΩ or more?

Yes No

Replace the fuse with a new part, and connect the secondary air pump connector.

Repair ground short of the harness between the fuse box and the secondary air pump.
