Nissan Micra K12 1.4 ECU Swap

**gurmk** · 26th March, 2014, 03:44 PM

Got a Micra K12 1.4 with Faulty ECU. Got a complete ECU set from the breakers (ECU, BCM, Steering lock, Central locking box, Fuse box, Instrument Cluster and the Smart Key).
Fitted all even though I am sure I did not have to change the Fuse Box or the Instrument Cluster. Car locks and unlocks with the supplied key, when you get in the car the "Green" KEY lights up but the moment you try to start the car the red key symbol show and nothing happens.
Tried to re-program the key with the 12 digit Sec which I got using ICC after reading 93C66 form the ECU and got incorrect sec code.
Is it possible that the Power Steering is stopping the car from starting and stopping the key getting programmed.
If so can the Power steering be reset or Virginlised?
Any help will be greatly appreciated.

Hi
I am working on simular projects.
I would first - post the 12 dig number on the label in the glove box and get the 12 dig code confirmed.
As they are noted for loosing their keycode I would try to re-code the key, to be honest I dont think it will solve the problem.
Get a used ecu with the same part number and swap the eeprom, if faulty ecu is just the problem then the car should start.

Glove Box, that's the first thing I looked for but it was missing hence the reason for getting the pin code from the ECU
