Toyota Sienna Service Manual: Power Slide Door RH 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 RH, 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 RH 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 RH.

INSPECTION PROCEDURE

1 OPERATION CHECK

1. If the power slide door does not operate when trying to open it, proceed to A.
2.  If the power slide door does not operate when trying to close it, proceed to B.

2 CHECK SLIDE DOOR CLOSER SYSTEM

1. Check if the slide door closer system operates.

3 READ VALUE OF INTELLIGENT

1. Using the intelligent tester, check the DATA LIST for proper functioning of the handle operation detect switch.

OK (Power slide door ECU RH):

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

1. Inspect the resistance of the switch.

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

1. Disconnect the S23 remote control and P27 ECU connectors.
2. Check the resistance between the wire harness side connectors.

Resistance (Check for open circuit)

3. Check the resistance between the S23 remote control connector and body ground.

Resistance (Check for open circuit)

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

1. Disconnect the S23 switch and P27 ECU connectors.
2.  Check the resistance between the wire harness side connectors.

Resistance (Check for open circuit)

3. Check the resistance between the S23 switch connector and body ground.
