Son of Nod Posted November 15, 2017 Share Posted November 15, 2017 Hello all.... We ve been advised to replace the ECU in our 06 Zetec Focus. Error found in module today causing limited power mode. Where can I find the long serial number in the engine? Thank you in advance. Quote Link to comment Share on other sites More sharing options...
JW1982 Posted November 15, 2017 Share Posted November 15, 2017 To identify the PCM there is a label/sticker on the PCM. Among some other numbers the PCM part number and tear tag number are printed on the label/sticker. Both numbers can be used to identify the PCM. the PCM hardware number can also be obtained using a suitible Ford specific diagnostic system.

In the engine or as seen on YouTube glove box? Quote Link to comment Share on other sites More sharing options...
JW1982 Posted November 15, 2017 Share Posted November 15, 2017 The location of the PCM depends on the Focus version (MK1, MK2 or MK3) and the engine type. Quote Link to comment Share on other sites More sharing options...
Son of Nod Posted November 16, 2017 Author Share Posted November 16, 2017 Doesn't really help me that. Is it behind the glove box? Quote Link to comment Share on other sites More sharing options...
JW1982 Posted November 16, 2017 Share Posted November 16, 2017 To answer that question you need to give some more info first. What type of Focus do you have ? (MK1, MK2 or MK3). What type of engine does your car have ? Based on this info I can tell you exactly where the PCM is located. If Your car is a 2006 Focus MK2 the PCM is installed in the engine bay. The exact location however is different for most engine types. 1 Quote Link to comment Share on other sites More sharing options...
