Inspection Procedure

WARNING: This page is about a different car, the 2004 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.

OPERATION CHECK
1. If the power slide door does not operate when tying to open it, proceed to A.
2. If the power slide door does not operate when tying to close it, proceed to B.
1. B: Go to step 3
2. A: Go to next step.
CHECK SLIDE DOOR CLOSER SYSTEM
1. Check if the slide door closer system operates.
1. NG: GO TO CLOSER SYSTEM (See SLIDE DOOR CLOSER RH DOES NOT OPERATE )
2. 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):

POWER SLIDE DOOR ECU RH

Item	Measurement Item/Display (Range)	Normal Condition	Diagnostic Note
HANDLE SW	Handle operation detect switch signal	ON: Slide door inside/outside handle is pulled	-
HANDLE SW	/ON or OFF	OFF: Slide door inside/outside handle is not pulled	-

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:

TERMINAL 1-3 CONDITION

Terminal No.	Lever Position	Specified Condition
1 - 3	Unlock	10 kΩ or higher
1 - 3	Lock	Below 1 Ω

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):

TERMINAL S23-1 OPEN CIRCUIT

Terminal No.	Specified Condition
S23-1 - P27-3 (HSW)	Below 1 Ω

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

Standard (Check for open circuit):

TERMINAL S23-3 OPEN CIRCUIT

Terminal No.	Specified Condition
S23-3 - Body ground	Below 1 Ω

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):

ECU RH MEASUREMENT CONDITION

Item	Measurement Item/Display (Range)	Normal Condition	Diagnostic Note
CHILD LOCK SW	Child protection detect switch signal	ON: Child lock lever is LOCK	-
CHILD LOCK SW	/ON or OFF	OFF: Child lock lever is UNLOCK	-

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 CONNECTOR TERMINALS SPECIFIED CONDITION

Terminal No.	Lever Position	Specified Condition
4 - 5	Unlock	10 kΩ or higher
4 - 5	Lock	Below 1 Ω

NG: REPLACE SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSY RH
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):

TERMINAL S23-5 OPEN CIRCUIT

Terminal No.	Specified Condition
S23-5 - P27-18 (CPSW)	Below 1 Ω

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

Standard (Check for open circuit):

TERMINAL S23-4 OPEN CIRCUIT

Terminal No.	Specified Condition
S23-4 - Body ground	Below 1 Ω

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
OK: REPLACE POWER SLIDE DOOR ECU RH
