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.
