Toyota Sienna Service Manual: Power Slide Door LH does not Operate When Using Inside / Outside
Handle
DESCRIPTION
- The inside / outside handles have the ability to control operation
of the power slide door. Pulling either
handle transmits a request signal to the power slide door ECU LH, which then
commands the power
slide door control motor and clutch to open / close the power slide door.
- The slide door lock remote control assembly has the handle
operation detect switch for detection of
switch operation and also the child protection detect switch for the child
lock function that disables the
power slide door control switch LH function while the child lock is ON.
- If there is a malfunction detected in these 2 detection switches
or the wire harness, replace the slide
door lock remote control assembly LH.

INSPECTION PROCEDURE
1 OPERATION CHECK
- If the power slide door does not operate when trying to
open it, proceed to A.
- If the power slide door does not operate when trying to
close it, proceed to B.
2 CHECK SLIDE DOOR CLOSER SYSTEM
- Check if the slide door closer system operates.
3 READ VALUE OF INTELLIGENT TESTER
- Using the intelligent tester, check the DATA LIST for
proper functioning of the handle operation detect switch.
OK (Power slide door ECU LH):

4 INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSEMBLY LH (HANDLE
OPERATION DETECT SWITCH)

- Inspect the resistance of the switch.

5 CHECK WIRE HARNESS (SLIDE DOOR LOCK REMOTE CONTROL - POWER SLIDE
DOOR ECU LH)

- Disconnect the S20 remote control and P25 ECU
connectors.
- Check the resistance between the wire harness side
connectors.
Resistance (Check for open circuit)

- Check the resistance between the S20 remote control
connector and body ground.
Resistance (Check for open circuit)

REPLACE POWER SLIDE DOOR ECU LH
6 READ VALUE OF INTELLIGENT TESTER
- Using the intelligent tester, check the DATA LIST for
proper functioning of the child protection detect switch.
OK (Power slide door ECU LH):

7 INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSEMBLY LH (CHILD
PROTECTION DETECT SWITCH)

- Inspect the resistance of the switch.
Resistance

8 CHECK WIRE HARNESS (SLIDE DOOR LOCK REMOTE CONTROL - POWER SLIDE
DOOR ECU LH)

- Disconnect the S20 switch and P25 ECU connectors.
- Check the resistance between the wire harness side
connectors.
Resistance (Check for open circuit)

- Check the resistance between the S20 switch connector
and body ground.
Resistance (Check for open circuit)

Intermediate Shaft Speed Sensor "A"
DESCRIPTION
This sensor detects the rotation speed of the counter gear. By comparing the
counter gear speed signal
(NC) with the direct clutch speed sensor signal (NT), the ECM detects the shift
timing of the gears and
appropriately controls the engine torque and hydraulic pressure according ...

Removal
HINT:
Remove the RH side by the same procedure as the LH side.
1. REMOVE REAR WHEEL
2. DRAIN BRAKE FLUID
NOTICE:
Wash the brake fluid off immediately if it attaches to
any painted surface.
3. SEPARATE REAR BRAKE TUBE NO.4
(a) Remove the clip and a disconnect, the rear brake
