Fuel: Petrol
Ref: ECUT31175

Note: This ECU may also fit other models.

An engine ECU labelled 94AB-12A650-EB, with the word ENVY printed after the number, is on record from the Ford Escort, and from the Escort 1.6 in particular. The same Ford number is on record as an SME-105 unit.

That label is worth reading closely, so the sections below take it one part at a time, then turn to the second number we list and to getting a unit to us. Whichever number yours carries, we repair it at component level, on the unit you send.

Reading a 94AB-12A650-EB label, part by part

The Ford number is the part that decides the row. Read it from your label in full, from 94AB at the start to EB at the end, and check it against the table at the foot of this page.

SME-105 is on record printed alongside this number. If your label carries it, it tells you the unit belongs on this page; it does not stand in for the Ford number when it comes to choosing a row.

The car adds background rather than proof. An Escort 1.6 fits what is on record for 94AB-12A650-EB, and it is worth telling us about, but the label is still the deciding evidence.

ENVY, the quick check beside the number

ENVY is printed beside 94AB-12A650-EB on labels, and the pairing is on record from 12 sources. Our table carries the same word on the same row.

A four-letter word can be taken in at a glance, which makes it a fast first check. A label reading ENVY points you to this row before you have compared the last two letters of the number.

Copy it along with the number, not in place of it. The two together are what we check your unit against, and a label that gives both leaves nothing to guess.

How the first four characters separate our two rows

The second number we list is 94FB-12A650-CC, and our table prints the word CULT after it.

The two numbers begin differently, 94AB against 94FB, so the opening characters alone are enough to tell the rows apart. Their endings differ too, EB against CC, and so do the words.

Even so, copy the whole number and the word rather than stopping at the first four characters, so that we match everything the label gives.

Our table prints both numbers without their hyphens, so 94AB-12A650-EB appears there as 94AB12A650EB, with ENVY after it.

Diagnosis and repair, carried out in-house

Every unit we take in is repaired by our own engineers, in our UK workshop and on our own equipment. The work stays with us from start to finish; no part of the job is subcontracted.

When your unit arrives it is logged, looked over by eye and tested electrically, and diagnosis then works from the fault you reported. We contact you with our findings and an estimate, and chargeable work begins only once you have given the go-ahead.

Component-level work is done under a microscope with temperature-controlled rework equipment, and the unit goes back to you only after passing final testing. The work we did on it is covered by our 24-month warranty.

Posting an SME-105 engine ECU to us

Send your unit to us by post, from anywhere in the UK. Before it goes in the box, note the label, as you read it, on our Repair Form: the full Ford number, the four-letter word after it, and SME-105 if your label shows the name.

Mention the car the unit came out of as well, with its engine size, and describe how the engine behaved once the trouble started. That account shapes where diagnosis begins.

If your label matches neither number here, look through a separate list of Ford EEC-IV part numbers. Ford labels of another kind lead to the Ford engine ECUs covered elsewhere on our site, and for other marques, browse our engine ECU repairs by car make.

Both numbers appear below as our table prints them, each followed by its four-letter word.
