Hi

i was wondering i have a toyota rush 2005 with c transponder
recently i did a job chip crashed or somthing but car did not want to start

i removed the immo key free box and read the dump
wrote a new key in it to he file and put it back in the car
nou ignition switch unlocks all lights on dash come on and gooff excaped for check engine immlight also tuns off witch i think it is ok so i try to start it crancks but no start

so i scanned the car and got code P1601 witch has somthing to do with immo mis match or somthing sorry cant remeber exact

read somwhere i need to resyncethe immo and the ecm by shorthing pin 4 and 13 on the obd port and leave it for 31 min

did that but code is stil there and car no start condition

so my question has anyone had this problem and how can it be resolved

ps sorry for the long post

kind regards mehmet

Hi
it maybe key itself
you might need to make 2 keys/ 1 master key/1 slave key as some toyota need 2 keys to start car
you first need to make master then program slave key
tpx1 make universal key
im adding zip file which might help you understand car system better
let us know how you get on
