Hello out there,

I've put a 2000 4Runner engine into my 1988 4Runner. The engine will run for 15 to 20 seconds and then shuts down. the fault code is P1300. There seems to be a problem with the ECU looking for a security device which of course I don't have. Does anyone know how to disable the ECU looking for a security system? I'm at a total loss.

 

could it be the chip in the key which you dont have?

 

P1300 code is a ignitor circuit malfunction. The vehicle would not start at all if it was the immobilizer.

 

Thanks for the replies. When you cross referance the P1300 code over to Toyota it says that it is a security problem. The question I need answered is if anyone knows how reprogram the ECU or knows of a way to make it think the security system is engaged. Thanks Mike
