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 trying to open it, proceed to A.
2. If the power slide door does not operate when trying 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 HOW TO PROCEED WITH TROUBLESHOOTING )
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 LH):

POWER SLIDE DOOR ECU LH STANDARD

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 LH (HANDLE OPERATION DETECT SWITCH)

Inspect the resistance of the switch.
