TSB No. 0832 is now obsolete and should be discarded.
INTRODUCTION:
Sliding door cable adjustment may be necessary if the Sienna power sliding door becomes inoperative, intermittently inoperative, does not close properly, or returns to an open position when trying to close the door using the power switch or remote control.
NOTE:
The sliding door can always be operated manually with the main power switch turned off.
The following information provides helpful details on the power sliding door cable adjustment procedure outlined in the Repair Manual.
APPLICABLE VEHICLES:
- 1999 - 2003 model year Sienna vehicles.
WARRANTY INFORMATION:
REPAIR PROCEDURE:
Vehicle preparation: (This is a two-person operation.)
NOTE:
ALWAYS disconnect the negative (--) battery terminal BEFORE adjusting the cables.
1. Remove all second and third row seats from the vehicle.
2. Remove the interior quarter trim panel (look for a screw hidden behind the rear lower A/C air inlet panel). (See Figure 1.)
3. Remove the large black-coloured A/C duct connecting the evaporator housing upward toward the air distribution duct work.
4. Manually open the power sliding door to the halfway open position.
Track cover removal:
1. Remove the outer track cover (body-coloured plastic cover located below the right rear quarter window).
A. From inside the vehicle, use a small diameter 12-in. to 18-in. long flatblade screwdriver to detach the 2 small rearmost retaining clips that attach the outside moulding to the body sheet metal (see Figure 2).
B. Once the clips have been popped loose, remove the screw at the front edge of the outside moulding, and slide the body-coloured moulding forward until the moulding has cleared all attaching clips.
C. Once the moulding has been removed, detach the plastic clips from the body and reattach them to the body-coloured moulding.
D. Set the moulding aside for later installation.
2. Manually close the power sliding door all the way.
Adjust cable tension for inner and outer cables:
1. One tensioner at a time, grasp both tensioners and align them with the white marks on the housing as shown in Figure 3.
2. Once the white marks are aligned on both tensioners, insert locating tools into the 2 holes using any of the following:
- Plastic pins (supplied with a NEW power drive assembly)
- 2 1/2-in. diameter wooden dowels
- 2 No. 2 Phillips screwdrivers
Figure 3 shows a view from inside the vehicle with 2 screwdrivers in the proper position. Plastic pins or wooden dowels may be used in place of screwdrivers.
3. Technician No. 1 inside the vehicle should have a 6- point 14-mm socket/ratchet wrench ready for use.
4. Using the outside door handle, Technician No. 2 should manually open the sliding door slowly, while Technician No. 1 inside the vehicle looks through the stopper window until a blank section of the internal drum appears through the window (look for a section on the internal drum that has NO ribs attached). (See Figure 4.)
NOTE:
- The stopper window is located on the side of the motor drive assembly as shown in Figure 4.
- The internal drum has a blank section and a ribbed section that will appear through the window as the internal drum rotates when Technician No. 2 opens the sliding door manually.
NOTE:
Do NOT push the 14-mm nut inward - this will release the tension on the drum assembly.
5. Once the section of the drum without the rib appears in the stopper window, Technician No. 1 should insert a No. 2 Phillips screwdriver into the stopper window. (See Figure 4.)
6. Once the screwdriver is in place, slowly move the sliding door toward the open position until the screwdriver becomes wedged between the internal drum and the motor housing.
The door should be open approximately 1 inch at this point. If it is NOT, try to move the door until it is open approximately 1 inch (with the screwdriver still wedged in place).
7. Technician No. 2 (outside of the vehicle) should grasp the exposed rear cable (near the center roller) and pull on the cable using very light tension (see Figure 5).
Keep tension on the cable at all times.
8. While Technician No. 2 outside continues to keep tension on the outside cable, Technician No. 1 inside should attach a 14-mm 6-point socket/ratchet wrench the plastic adjusting nut (attached to the inner drum assembly).
Technician No. 1: Rotate the nut counterclockwise. (Refer to Figure 6.)
Technician No. 2 (outside of the vehicle) should start see the slack being removed from the outside cable as the plastic 14-mm nut is being rotated counterclockwise.
As soon as there is NO longer any slack in the outside cable, stop rotating the nut and remove the socket/ratchet wrench from the 14-mm plastic nut.
9. Remove the tools that were inserted in the drive unit (screwdrivers or plastic pins or wooden dowels).
10. While watching the operation of the rear outside cable, Technician No. 2 (outside the vehicle) should manually close the sliding door completely, then manually open the sliding door all the way, and then manually close the sliding door completely.
NOTE:
Both the inside and outside cables should now be properly tensioned.
If the rear cable appears to have any slack in it at any time, the cable adjustment procedure MUST be repeated until all the slack is removed.
IMPORTANT:
Re-initialize the electrical system after reconnecting the battery. Refer to TSB No. 0953, "Power Sliding Door Diagnostic Procedure," for initializing procedure details.
11. Before reassembling the vehicle, confirm that the power function of the sliding door operates properly by pressing the power button in any of the following locations:
- the door B-pillar
- the dash
- the handheld transmitter
