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

1. Re-Initialize the Sliding Door System

A. Single Power Sliding Door - re-initialize according to step 2 of TSB BO030-00 " Power Sliding Door Diagnostic Procedure".

B. Dual Power Sliding Doors - re-initialize according to TSB BOO35-00 "Dual Power Sliding Door Re-Initializing".

2. 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. Electrical Contacts at the Front of the Door.





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

B. Confirm proper door operation.

4. Door to Body Adjustment.

A. Push main power switch (located on left side of steering column) to "OFF" position.





B. Manually open sliding door to "full open" position, then slowly close door to "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 the 2000 Model Repair Manual Instructions on page BO-22.

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

5. Rear Striker Adjustment.





A. Confirm the rear latch moves to the full latch position when the door is closed.

B. Adjust the striker on "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, according to the procedure in the 2000 Model Repair Manual, page BO-23.

D. Confirm proper door operation.

6. Cable Tension Adjustment - Rear Latch to "L" Bracket

A. Remove interior trim panel for power sliding door.

B. Carefully remove plastic sheeting attached to the metal door panel. Do not damage plastic sheeting during removal (plastic must later be re-installed in the original position).





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