1S6F-12A650-CA and 1S6F-12A650-CB are both on record as LP4-322 units from the Ford Fiesta 1.3, and a unit carrying either number is repaired here at component level, by our own engineers in our own UK workshop. The work is carried out on the board inside your own unit, and that same unit is the one we return to you.

To match a unit to this page, take two things from its label: the Ford number, read in full, and the short word printed after it.

1S6F-12A650-CA and CB, recorded as LP4-322

1S6F-12A650-CA, with the word OYBU after it, is on record as an LP4-322 unit from the Ford Fiesta 1.3. The same is on record for 1S6F-12A650-CB, which carries the word OBEW: an LP4-322 unit, from the Ford Fiesta 1.3.

Both numbers begin 1S6F-12A650, and the letter that closes each one, A or B, is what separates them. If that letter has rubbed away, the word after it gives you a separate check against our table.

Listings print the word for 1S6F-12A650-CA both as OYBU, with the letter O, and as 0YBU, with a zero in its place, so a label that seems to read 0YBU is worth checking against this row.

1S5F-12A650-AA and the Ford Ka 1.3

1S5F-12A650-AA is on record from the Ford Ka 1.3. It is the first row of our table, printed there as 1S5F12A650AA with its own word after it.

A Ka unit with this number is booked in through the same Repair Form and goes through the same process on our bench as every other engine ECU we repair, as set out in the last section below.

1S5F or 1S6F: the digit to check first

The two bases in our table, 1S5F-12A650 and 1S6F-12A650, are identical except for their third character, a 5 in one and a 6 in the other. On a scuffed or faded label those two figures are easily mistaken for each other, and nothing either side of them helps, because the 1S before and the F-12A650 after are the same on both.

So read that third character first, then the ending. In our table, AA sits on the 1S5F base, while CA and CB sit on 1S6F, which means the base and the ending together point to a single row.

The only other difference to allow for is presentation. Our table prints every number without its hyphens, so 1S6F12A650CB on this page is the same number as 1S6F-12A650-CB on a label.

The postal route, the bench and the warranty

We work as a mail-in service covering the whole of the UK. Before you post the unit, lodge the Ford number, its word and the symptoms with our Repair Form.

Once the unit is with us, it is logged, given a visual inspection and an electrical test, and then taken through diagnostics specific to its fault. You then hear from us with the outcome and an estimate, and no chargeable work begins until you have authorised it.

Our engineers make the repair at component level, under a microscope and with temperature-controlled rework equipment, and the unit is not released until it passes final testing. That repair is protected by our 24-month warranty.

For a Ford unit whose label shows a number not listed here, look through every Ford engine ECU we repair, whatever its code. If the car is not a Ford at all, go to engine ECU repairs for cars wearing a different badge, and for an overview, see the engine ECUs our repair service is built around.

The three Ford numbers covered on this page are set out in the table below.
