I have Toyta Prius V/alpha/plus 2016. I have removed damaged automatic window closer. After I have bridge the wires by matching same colors, I have a problem with driver's master windows switches: I'm unable to control all other 3 windows and I can't use the locking button. I can only control from driver side only driver window without power window. From each passenger door I can control the related window. I have run Techstream and as far as I understand there is no LIN communication, enclosed. 1. What are canbus high and low colors from window maser switch? 2. From the master window switch where it should be connected to which pins numbers and where? 3. In the kick panel I pictures the wires, what is black-white color wire? if some have wires color and their description , it will be very helpful. BR, Nir
Not clear what you mean by "automatic window closer". Do you mean the motor assembly? There is no canbus to that switch. Only a single line Lin bus which is different. It is normally a pink wire. Not sure why you spliced in a new connector but that is a likely problem area.
Thank you for your answer. Automatic window closer is a module that close all car windows after pressing lock on the car key remote control. So you mean that if there's no connection between the master window switch in the driver side, that probably the pink wire? From window switch panel, what's the path of the wire to the ecu? What is the role of the yellow wire in the driver's window switch panel? Thank you, I appreciate your kind assistance Nir
I still don't understand if you removed a module without replacing it and why you are splicing a connector. The Lin Bus goes through some connectors back to Pin 16 of the Main Body Ecu. It's pink all the way to the Body ECU. Yellow in the schematic I posted drives a led indicator. The other three window motor assemblies also connect to the same wire.
"I still don't understand if you removed a module without replacing it and why you are splicing a connector." Answer: The automatic windows closer was connected directly by wires to kick panel's wiring, this unit is faulty and I throw it away. Now, I purchased a new unit that is connected to other area (under the steering wheel), the new unit is also locking the doors after shifting to "drive". Sorry for drilling down: after removing the door cover panel the power windows switches are connected to the door connector. The door connector wires goes to the area of the kick panel. The kick panel is the area where I disconnected the automatic windows roller and bridged the wires. 1. How to recognize the wires that come from the door connector to the kick panel? 2. How to recognize the wires that come from kick panel area to the multiplexer network and to the ECU? 3. According to the scheme you sent me, just to clarify the physical location: is "O6" is located in the kick panel? 4. The yellow wire the goes to door's power windows switch is responsible to to led of each windows switch? I'm asking that question because the phenomenon now is that the only window led in indicator that is lighting is the driver and only after I press the window switch. I wonder if it relates to the communication problem (pink wire) or to the led problem (yellow wire). Enclosed 2 pictures of the old automatic windows up roller (with directed wires soldering). Enclosed the new module with plastic connectors. Thank you, Nir
It looks like some optional module (not original factory) was added by splicing into the wiring harness. It would be useful to have a clear picture of the above module's label. I can see Toyota but the factory would not have installed it that way. See below. Kind of wonder if it's a security add on and not just a window closer. It is very possible the previous device needed the Lin bus, power and ground along with other connections to suit its purpose and therefore was manually wired in. You disconnecting it may have broken the Linbus connection. Other wires a security addon may have tapped includes things like door locks and lights. Having the original device's install instructions would help in properly removing it and restoring the wiring to factory. As is we don't know for sure what it was and or what was its function. This following pic is certainly an obd2 device or addon connector. You can see OBD on the label and the big connector is obd2 style. Where did you get it and who said this is what you need? Assuming the old and new modules are some addon device, normally they would come with their own wiring instructions. Sometimes newer addon devices will use a car's obd2 diagnostic port to add features or to enable data monitoring or data collection. The obd2 port has 12v power and ground and has the vehicles Canbus on it. Normally the Lin bus is not on the obd2 port. I would get back to the seller of the new device and ask for instructions. Plus find the instructions for the old device.
