Hello any solutions
only ktag read this ecu

[Mr Mo]

Thank you friend do I need to do a full read on this Ecu for immo or just swop eeprom that's what I did

[S.W.A.M.I]

swap eeprom is all you need for immo

is ecu getting power?

have the customer check for other faults

[Mr Mo]

Thank you Swami for reply i did go meet the Client however he Says he getting comunication on Ecu to Diagnosis but no engine light i found that abit strange , can only be if Ecu is not right for this vehicle s? i ran numbers on Ecu on Google and his old Ecu came up for his navara but the New Ecu is from Nissan frontier

[Mr Mo]

The c?des on the Ecu flashes are different but the circuits are same

[S.W.A.M.I]

what are the numbers/codes on the ecus (new and old)?

what diagnostic codes are you getting ?

[Mr Mo]

I'm not sure about Ecu fault codes customer refuse to tow his vehicle I did call up Nissan with the part number for the new Ecu and they said its a perfect match . I'm still stumbled as no check engine light but the old Ecu show check engine

[Mr Mo]

This Ecu is brand new

[S.W.A.M.I]

unless the old immo chip is damaged/corrupt, i see no reason for it not to work.
no engine check light with diagnostic communication is usually a symptom of an ecu power supply issue or internal fault

the DTC codes are essential at this stage.

its simple it means that u damage some thing when u open the ecu , why would u open this ecu when u could do the job with tcode pro , mvp pro etc ?
there was no need to void warranty on a brand new ecu . your next option is to get one on ebay for 100 pounds and program via obd .

Lol I'm not that careless with ecu but thanks for ur advice

[Mr Mo]

Yes he is getting communication with ecu however I will order another ecu to try and keep u updated thank you guys

This Ecu is brand new
Plug in the car and program
IIRC new ecu's are 'blank'

[matt224200]

every thing must match if it all matching 2 the car then it will have 2 be flashed all back. any Nissan just change the ecu/bcm on the car out. with matching number in the car. i had 2 tell an few car shops this once they changed with matching number every key program in as long as the chips are good.
