Subject: xk05 bypass programming
Date Posted: December 18, 2010 at 12:52 AM
I am using this on a toyota corolla 2010. I cannot seem to get this to program. All my wires are correctly placed.
I have teh brown GWR connectd to the keysense, i heard somewhere that i should remove this. I have tried BTW.
when i try programming it with a key, i turn to IGN and the red LED comes on. I turn the car on and it just cranks with no turn on. when i turn the key off the LED goes out.
when i connect the pink IMI wire back together the car turns on just fine. I HAVE tried switching the IMI wires in the case i got them backwards, same result.
I have also tried tricking the bypass by... while having the pink IMI wire connect to each other i turn the key to IGN. i turn the car on and off and leave it on IGN. so the red LED is on. i then attach the IMI wires to the correct wires on teh bypass (i am using gator grips not solder while testing) then when i turn the car on it turns on but then a second or two later it turns off. i get the same results when trying the remote start.
I have tried everything how can i get this thing to program. I have a XK05-PKT2.
thanks

What band / model remote starter? Are you running D2D with the D2D 4 Pin harness connected? Or are you running W2W with no D2D harness connected and the +12v, ground and GWR connections made via the 10 Pin harness?
The XK05 Brown Ground When Running wire should only be connected to the remote starters' (-) 200mA Status Output, assuming W2W mode, never to the cars' Keysense wire. You want the remote starter to control the XK05 and not have the XK05 turned on whenever a key is in the ignition.
Follow the guide and wire in either D2D or W2W mode only. Then do a XK05 module reset. Verify all connections are properly made. Then program to the car. ------------- Soldering is fun!

Thank you for the reply.
I am running W2W without the D2D cable connected. The remote start I am using is a RS 160 (https://www.jcwhitney.com /jcwhitney/sku/documents /InstallationInstructions_144.pdf)
Here is my setup https://i1113.photobucket.com /albums/k501/Syn664 /Untitled-1.jpg
I have a diode on the Keysense blue wire. and there is a typo on the parking switch (it says keysense)
I am not sure which is the remote starts 200mA status output. is that the black "ground for OEM bypass modeule -)? If i connect the brown GWR to the black ground for OEM and then connect the XK05's loose black wire to a chassis, will i get better luck?
thank you very much!

the ground when running goes to the status output of the remote start unit, then the red from bypass to 12v and black to ground

Is the status output on the remote start "Ground for OEM bypass module"?
and does the violet/white GWR out of the remote start still go to the keysense?

The Black Ground for bypass is just a constant ground. It can be connected to the bypass Black wire. The Violet/White Ground When Running wire goes to both the bypass Brown wire and the cars' Keysense wire with diode isolation. (Keysense is only necessary if you have the Toyota Factory Alarm system.) Typically I connect the XK05s' Red wire to the RS160 thick Red +12V Battery wire and the XK05s' Black ground to the RS160s' Black Ground Input wire ( next to the White Parking Light wire ).

Ah ok. It looks like everything in my diagram is correct then. I have the brown going to violet/white and those go to a diode which goes to the keysense. I cannot find any problems in my diagram. I am completely out of ideas....

Everything looks good. Does the bypass program as per the install guide? Where does it differ / fail ?
Are you sure the XK05 has the PKT2 firmware loaded on it? I would re-flash the XK05 module and try again.
Also, is this an 80 Bit key? Is there a "G" stamped on the blade? If not you could try the XK05 with the 5.PKTI firmware. It is an easier install with all the connections at the ignition switch in the steering column. ------------- Soldering is fun!

Thank you very much for your time. I have ordered an xloader to flash the kit. I bought it with PKT2 but I do not know for sure. I have a 40 bit key, no G on it. We will see how it goes when the kit gets here. Thanks a lot!

Try this. Can't find any mention of needing key in sense.

Ok! i finally got my XKloader. I put on the 5.PKTI firmware and re-wired for it. I have run into programming problems again.
The xpresskit site says it requires 2 keys to program a toyota. but the directions they give me only shows how to program using 1 key. I have tried using one then switching to the other. It will not program (the LED will not go out).
I have managed to trick it a few times by switching the RX and TX while the car was running and this would actually program the module but when i try using a key or the RS it wont catch. I have flashed multiple times during programming attempts.
any ideas? ( I attached the bypasses ground to a chassis like jkxmlr has mentioned)

The XK05 with 5.PKTI firmware should work as long as the Ignition key does not have the "G"
stamped on the blade. While your diagram does not show it, the 4 Pin D2D cable is not necessary
and should not be connected. Only the 6 wires shown from the 10 Pin connector are connected.
The wiring looks good for a Japan made car. The info I have says RX is Light Blue on Pin 4 and
TX is Beige on Pin 5. Keysense(-) is also Light Blue but on a seperate connector. Double check
your Keysense with a DMM. (The module uses Keysense to program.) All of these connections
should be soldered. Only one Key is required for programming. ( Fords need two keys. )
The correct programming for a Toyota is Type 1 on Page 8 of the install guide. If the modules LED
does not flash quickly and go off when a key is inserted, triple check the Keysense connection. I
would reset the module by re-flashing it with the 5.PKTI firmware and start programming again. As
the instructions indicate, at step 1, when the modules' 10 Pin connector is attached, the LED should
come on solid. At Step 2, when the key is inserted, the LED should flash quickly and then go off.
Two keys, different keys, switching wires, etc is not required. A solid reset of the module by flashing
it with PKT2 firmware and then back to the 5.PKTI firmware wouldn't hurt. If you are re-flashing
in the car, make sure the 10 Pin connector is removed during the re-flash. ------------- Soldering is fun!

Solid chasssis ground is good. But disconnect "GWR OEM bypass module". Also disco the two factory alarm wires. I think maybe things are getting FUBAR with reading inputs as outputs and vice versa. Can always re-connect later if doesn't help. Go simplest first, when working, add things you believe you need hooked up 1 at a time. If it quits, dixco.

Yea i have a 40 bit key, no G on the key. I have tried removing the alarm wires and disconnecting the GWR. I have tried messing with the 2 keysense wires. still the same result. https://www.youtube.com/watch?v=Xm6I-gh9Bwc
I made a video of where i am to give a bit more information. would the connections from the RS affect the bypass modules programming?

According to iDatalink install guides, the Keysense wire is Light Blue. Did you, can you, test this with a DMM?
PM sent. ------------- Soldering is fun!

I have tried programming it with the green XK05 wire attached to the chassis. and removed the brown GWR from the remote start. no luck. I have tried many variations attached to the blue keysense wire as well as the WHITE/ black one. I have tried all that again with the TX and the RX switched. I have confirmed the pin locations and have no doubt I have the correct wires.
I have checked the keysense with a DMM and confirmed it is the blue one.
I am at a dead end I believe. Seems like there is no way to get this thing to program. I may have to buy another bypass module, perhaps one with a different make. Does anyone have any recommendations for a almost full proof toyota corolla 2010 S 40 bit bypass module?
And if anyone ever has any other ideas, I would love to try it!
thank you!

Only other thing I can add is to solder the data connections, connect everything as shown in instructions and try it. Remember, its data your passing, not just voltage. Changing wires around may fry something. I had a need to call Xpresskit tech support and soldering data connection was enphasised. Have you tried tech support?

It's working!!!!!
I ended up buying a ADS TB bypass with an adapter and flashed the correct Toyota firmware. Worked on the first try with no issues. The car is all cleaned up and looks perfect now with a working remote start.
I appreciate the help along the way and for anyone thinking of a Corolla 09+ bypass... I suggest you avoid the XK05.
Thanks everyone.
