Procedure
1. Disconnect 12V power (refer to Service Manual procedure 17010200).
2. Release the LH upper C-Pillar trim from the vehicle, and then set it aside (refer to Service Manual procedure 15186002).
NOTE: Do not release the seatbelt from the C-Pillar trim.
3. Wiggle the LH 2nd row seatbelt retractor and inspect for a gap between the retractor and the body.
• If the retractor does not wiggle and is tight against the body (Figure 1), the retractor bolt and weld nut do not require inspection; torque the bolt (torque 30 Nm), take note, and then skip to step 20.
• If the retractor wiggles or is not tight against the body (Figure 2), the retractor bolt and weld nut require inspection; take note and continue to step 4.
