APPLICABLE MODEL(S)/VINS

2006-2008 Mazda3 vehicles (including Mazdaspeed3) with VINs lower than JM1 BK**** ** 823850 ( produced before September 11, 2007)

DESCRIPTION

Some customers may hear a squeak and rattle from the front seats (mainly from the driver's side) when passing over a bump or driving on a rough road. This issue is due to an improper fitting between the wave washer and anchor bolt of the seatbelt buckle. The diameter of the wave washer is bigger than the bolt flange, which causes the wave washer to come into contact with the anchor bolt.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Verify concern.

2. Remove the front seat(s) with the noise. Refer to MS3 online instructions or Workshop Manual section 09-13 FRONT SEAT REMOVAL/INSTALLATION.

CAUTION: Handle the wires with care as they are for SRS.

3. Disconnect the seat belt switch connector from the front seat connector by detaching the tab as shown. If necessary, follow the wire harness from the seatbelt buckle.

NOTE: Disconnect the front seat connector from the seat frame if needed.

4. Remove the seat belt switch wire harness from the clip and cut the zip ties holding the wire harness to the seat frame.

5. Remove the front seat belt buckle bolt, then remove the buckle from the seat.

6. Install the new seat belt buckle and bolt.

Tightening torque: 40-50 Nm (4.1-5.0 kgfm, 30-36 ft-lbf)

7. Route the wire harness for the seat belt switch like it was before.

8. Install the wire harness in the clip and zip tie the wire harness in the two places where it was previously attached.

9. Connect the seat belt switch connector to the front seat connector.

NOTE: Connect the front seat connector to the seat frame if it was removed.

10. Install the front seat(s). Refer to MS3 online instructions or Workshop Manual section 09-13 FRONT SEAT REMOVAL/INSTALLATION.

NOTE: If the passenger's seat was removed, perform the Seat Weight Sensor Calibration.

11. Verify repair.

• Driver's side: With the driver's seatbelt buckle unbuckled, turn the ignition switch ON and verify seatbelt warning light is on. Then buckle the driver's seatbelt and verify warning light turns off.

• Passenger's side: With the front passanger's seatbelt buckle unbuckled, turn the ignition switch ON and verify passenger's air bag off indicator turns on, then off. Next, buckle the passenger's seatbelt and verify passenger's air bag off indicator turns on and stays on.
