Radio interference by disturbance from the fuel pump ass'y

If there are complaints about radio interference in the AM band in these vehicles, a possible cause of fault is the fuel pump ass'y.

- Check whether the signal interference is caused by the fuel pump ass'y.

If so, the vehicle manufacturer provides the interference suppression ring (spare part no. 30739380).

Installation note:

· Expose the multi-connector of the fuel pump wiring harness under the rear seat (right).

· Remove the wiring harness multi-connector (6-pin) from the mounting plate.

· Disconnect the cable at slot 6 (yellow cable) from the socket of the wiring harness multi-connector (use appropriate special tool).

· Remove the wiring harness insulation (approx. 140 mm) .

· Wrap the yellow wire three times around the interference suppression ring.

· Then reconnect the yellow cable to slot 6 in the socket of the harness multiple connector.

· Properly reinsulate the wiring harness and connect the wiring harness multi-connector.
