2009 Nissan Primastar immo problem

[Lexas]

hi. primastar/trafic immo problem. remote works perfect, but when turn on ignition, light blinks fast and van didnt starts. one fault 'transponder'...
is it possible that key code was lost even when remote still works? can i code same key or need new key/pcf?

yes the remote programmes when the key is learned so aslong as the key is stored the remote will work you can check the aerial and tp signal from the key

halo i have same problem where u was looking?? ant what connector clean?? help

[Lexas]

open uch and look under plugs. there is some parts behind plug. if you want to restore, need desolder plug, clean and resolder everything. then solder back plug. new uch is not so expensive at dealer. better get new and swap eeprom.

if u want to connect and do "CAN diagnostic" its says : no communication CAN to ecm.

take out instrument cluster and look thro the hole down, lower than steering wheel on right side (uk model) there you will see black box with two plugs. you need drill out one rivet on uch metal holder. then you will be able to disconnect plugs and take out uch.

check connectors in engine compartment as well. remove coolant tank, there is some plugs. disconnect them and spray with electric cleaner. more attention to purple plug.
