POWER SLIDING DOOR WON'T OPEN

2005 Toyota Sienna

Electrical problem
2005 Toyota Sienna 6 cyl All Wheel Drive Automatic 115000 miles

Recently our passenger side power sliding door stopped opening both automatically and manually. It no longer makes any noise when pushing the automatic button and is unable to be opened at all now. I have checked the door switch and made sure it was turned on, I have checked the fuses and plug-ins and all seem to be in working order. It is a huge inconvenience to have this door not functioning, I welcome any suggestions you may have that could assist me in troubleshooting this problem.
Thank You

Hello. Thanks for the donation. Much appreciated

I would start by having the vehicle plugged into a diagnostic computer to locate any body control ECU faults stored !

POWER SLIDE DOOR RH DOES NOT OPERATE WHEN USING INSIDE/OUTSIDE HANDLE
CIRCUIT 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 assy 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 assy RH.

OPERATION CHECK
If the power slide door does not operate when tying to open it, proceed to A.
If the power slide door does not operate when tying to close it, proceed to B.
B: Go to step 3
A: Go to next step
CHECK SLIDE DOOR CLOSER SYSTEM
Check if the slide door closer system operates.
NG: GO TO CLOSER SYSTEM (See SLIDE DOOR CLOSER RH DOES NOT OPERATE )
OK: Go to next step
READ VALUE OF HAND-HELD TESTER
Using the hand-held tester, check the DATA LIST for proper functioning of the handle operation detect switch.
Standard (Power slide door ECU RH): OK: Go to step 6
NG: Go to next step
INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSY RH (HANDLE OPERATION DETECT SWITCH)
Inspect the resistance of the switch.
Standard: HANDLE OPERATION DETECT SWITCH RESISTANCE SPECIFICATIONS
Terminal No. Lever PositionSpecified Condition
1 - 3Unlock10 kohm or higher
LockBelow 1 ohm

NG: REPLACE SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSY RH
OK: Go to next step
CHECK WIRE HARNESS (SLIDE DOOR LOCK REMOTE CONTROL ASSY RH (HANDLE OPERATION DETECT SWITCH) - POWER SLIDE DOOR ECU RH)
Disconnect the S23 remote control and P27 ECU connectors.
Check the resistance between the wire harness side connectors.
Standard (Check for open circuit): S23 REMOTE CONTROL AND P27 ECU CONNECTORS RESISTANCE SPECIFICATIONS
Terminal No. Specified Condition
S23-1 - P27-3 (HSW)Below 1 ohm

Check the resistance between the S23 remote control connector and body ground.
Standard (Check for open circuit): S23 REMOTE CONTROL CONNECTOR AND BODY GROUND RESISTANCE SPECIFICATIONS
Terminal No. Specified Condition
S23-3 - Body groundBelow 1 ohm

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
OK: REPLACE POWER SLIDE DOOR ECU RH
READ VALUE OF HAND-HELD TESTER
Using the hand-held tester, check the DATA LIST for proper functioning of the child protection detect switch.
Standard (Power slide door ECU RH): Fig. 80: Data List Item Reference Table

OK: REPLACE POWER SLIDE DOOR ECU RH
NG: Go to next step
INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSY RH (CHILD PROTECTION DETECT SWITCH)
Inspect the resistance of the switch.
Standard: CHILD PROTECTION DETECT SWITCH RESISTANCE SPECIFICATIONS
Terminal No. Lever PositionSpecified Condition
4 - 5Unlock10 kohm or higher
LockBelow 1 ohm

OK: Go to next step
CHECK WIRE HARNESS (SLIDE DOOR LOCK REMOTE CONTROL ASSY (CHILD PROTECTION DETECT SWITCH) - POWER SLIDE DOOR ECU RH)
Disconnect the S23 switch and P27 ECU connectors.
Check the resistance between the wire harness side connectors.
Standard (Check for open circuit): S23 SWITCH AND P27 ECU CONNECTORS RESISTANCE SPECIFICATIONS
Terminal No. Specified Condition
S23-5 - P27-18 (CPSW)Below 1 ohm

Check the resistance between the S23 switch connector and body ground.
Standard (Check for open circuit): S23 SWITCH CONNECTOR AND BODY GROUND RESISTANCE SPECIFICATIONS
Terminal No. Specified Condition
S23-4 - Body groundBelow 1 ohm
