PROPER DIAGNOSIS FOR CREAK NOISE:












The key to proper repair is proper diagnosis: duplicate the noise and isolate the source.






COMMON SOURCES OF CREAK NOISE:

NOTE:
Simply replacing all of these parts will NOT guarantee the source of the noise will be eliminated. The most important step is to isolate the location of the noise and determine which parts actually cause the noise.

REPAIR PROCEDURE:

Dash light "ON" -- Power door does NOT operate properly

1. Re-initialize the sliding door system.
- Single power sliding door -- Re-initialize according to step 2 of TSB No. 0953, "Power Sliding Door Diagnostic Procedure".
- Dual power sliding doors -- Re-initialize according to TSB No. 0920, "Dual Power Sliding Door Reinitialization".







2. Inspect rear latch operation.
A. Inspect operation of the rear latch.
Latch operation should be smooth and should NOT "hang up" on the striker when the door is being closed.

B. Lube latch arm and striker (where they make contact with each other) with "Door-Ease".
Confirm proper door operation.

C. Inspect the condition of the pins inside the connectors to confirm there is complete electrical contact.

NOTE:
The ECU is looking for two pulse signals from the rear latch when the door is moving to fully closed. If the ECU receives only one pulse signal, replace the rear latch assembly due to a possible micro-switch malfunction.







3. Clean electrical contacts (push pins) at the front of the door using an eraser from the end of a pencil.
Confirm proper door operation.







4. Adjust the door to the body.
A. Push main power switch (located on left side of steering column) to the "OFF" position.
B. Manually open the sliding door to the "full open" position and then slowly close the door to the "full closed" position.
Observe how well the door closes and fits against the body. If the door is NOT adjusted properly to the door opening, adjust the door accordingly to ETAS, applicable model year Sienna Repair Manual: Body (Mechanical): Slide Door: Adjustment.

C. After adjustment, push the main power switch to the "ON" position and confirm the door operates properly.







5. Adjust the rear striker.
A. Confirm the rear latch moves to the full latch position when the door is closed.
B. Adjust the striker on the C-pillar to the outward direction, in case the latch is in the half-latch position when the door is fully closed.
C. Adjust the rear striker.
Refer to ETAS, applicable model year Sienna Repair Manual: Body (Mechanical): Slide Door: Adjustment.

D. Confirm proper door operation.







6. Adjust cable tension of the rear latch to the "L" bracket.
A. Remove the interior trim panel for the power sliding door.
B. Carefully remove the plastic sheeting attached to the metal door panel.
Do NOT damage the plastic sheeting during removal (the plastic MUST later be reinstalled in the original position).

C. Locate the small cable that connects the rear latch to the slide door lock control.
The front portion of cable is attached to a gold coloured "L" shaped bracket.

D. Inspect cable tension by pushing on cable near the gold bracket.
There should be some deflection of cable when pushing on it with your finger. If cable is too tight, adjust the gold bracket to add some free-play to the cable. If free-play exists, do NOT adjust the bracket. Confirm proper operation of the power door.

E. Reinstall plastic sheeting and interior door trim panel.
Assure NO gaps occur between the plastic sheeting and adhesive used to attach sheeting to metal door panel.
