The Two Options I have Found by searching are..
1) Remove the Chip from the ECU, and Program it in the Burner with a Virgin Code..
2) Use a 'Chip Clip' to hook to the Chip while it on the Circuit Board.. and Program it there..

My Results..
1) Upon Further reading, unless you have VERY Expensive Soldering Tools for removing the Chip from the Board.. your Chances of getting it off, and back on and NOT Broken.. are ZERO.. So I Opted to not try that..
2) Purchased a Chip Clip that was for Hooking to the Chip.. to Program.. WELL.. while the Chip is in the Board.. and the Board is Covered with the Anti Fungus Covering.. not much can get through.. Not even the Contact for the Clip.. I tried to Scratch off the Coating.. I Got the Coating Off.. but was unable to get the Clip to Conect to all 8 Pins..

So I came up with Option 3..

Solder Jumpers to each of the 8 Pins of the Chip.. and take the 8 Wires to a header Jumper that will Plug into the Programmer ZIF Socket..

Here is the Pics..

Wires on the Chip..





Wires going to the Programmer..




I also came up with an Unusual Problem.. SOMETIMES on SOME ECU's I can not Erase/Read or Program Correctly.. Even though the Wires are Hooked up properly..

The Solution.. Power up the ECU, then Power it Down.. I have Test Plugs on the Bench.. So I can Do it from Inside the House..

Then the Chip will Read/Verify/Program with no Problems.. Not sure what that is about.. but I have a Work Around for it.. so Problem Solved..

One other problem has Surfaced.. This programmer has a default set up where it will electrically 'Taste' the leads of the E-Prom chip, to see if all is hooked up properly. As of late, the 'Taste' is different, and the Programmer thinks the leads are not hooked up properly..
The fix for this new problem, is to not 'Verify Leads' before programming.

You will need three keys for light to shut off. Two master and one valet. don't turn car on, just put the key in, wait two seconds then remove key. Add the other keys to memory by doing the same.
The First key inserted ( as long as not only one is Inserted ) will be Programmed as the Valet Key. Make sure if you have a Key that is cut as a Valet Key, it is inserted First.

Hi Zenovo

You cannot reset Toyota 4C systems through the ODB port. Tools like the AD100 will not work.

You can however reset Toyota 4D systems through the OBD port.

Your procedure should be correct.
1. Flash ECU with virgin file and refit to vehicle
2. Security LED should stay ON (Indicates Auto registration mode)
3. Insert first key remove and follow same procedure for 2nd and 3rd key. (First 2 keys will be programmed in as Master keys and the 3rd programmed as a Valet key)
4. Once 3rd key is removed security light should start flashing.

All finished

If you want to program less than 3 keys...... leave last key in ignition and depress brake pedal at least 5 times.

The other method for closing Auto Registration mode with Toyotas like cjawahir mentioned is key on - off 5 times but your corolla should be the brake method.

I did a 2004 Corolla with the same ECU recently. Generally your tutorial helped me up to the part with the security LED. After flashing with virgin file and refitting the light was blinking slowly(once per second). It stayed ON only after I plugged the first key. Since I had only one key, I wanted to cut the registration procedure after the first key but nothing happened after pressing the brake 5 times. The procedure finished only after I started the engine... But never mind, the job was done
