    Hello. I am looking for a specific, unambiguous answer to the question whether the FoCOM program is able to adapt the pump after replacing the driver? Some say that it is possible and others that not. Has anyone done the focom adaptation. If it can be done, I would ask for information on how to connect to the pump. Some say that after k-line, others that after CAN.

    focom will take over, by no means the Transit 2.4 with such a pump, time about 10 minutes and the generator needed for in-out codes

    Well, this is a problem because I do not have a code generator

    No generator is needed for the pump.

    None on the vp44 pump required in / out, only a 10min time delay, and FOCOM will do it without a problem.

    I confirm, a few focuses after replacing the pump in this engine were overwhelmed.

    Hello
    Have you made the pump adaptations using the standard OBD2 connector?
    Do you need any special?

    Unfortunately, due to the lack of the program, I had to lose 150 PLN and give someone to rip immo. From what ki is known, it is via obd. Taken with kts

    As my colleagues wrote above, I am going to do it. I couldn't do it, because the program failed and I gave it up. There was no time

Topic summary

✨ The discussion centers around the capability of the FoCOM program to adapt the fuel pump after replacing the driver in a Focus MK1 1.8 TDDI. Users express varying opinions on whether a code generator is necessary for this process, with some confirming that FoCOM can handle the adaptation without one, particularly for the VP44 pump. The connection method for the pump adaptation is debated, with suggestions of using either K-Line or CAN protocols. Several users report successful adaptations using standard OBD2 connectors, while others mention challenges faced due to program failures or lack of equipment.

FAQ

TL;DR: Focus MK1 1.8 TDDI VP44 pump adaptation with FoCOM takes about 10 minutes; “FOCOM will do it without a problem.” [Elektroda, adrian1201, post #16647103]

Quick Facts

Can FoCOM adapt the VP44 pump after a driver replacement on Focus MK1 1.8 TDDI?

Yes. Users report FoCOM completes VP44 pump adaptation after a built‑in ~10‑minute delay, with no in/out codes required. “FOCOM will do it without a problem.” [Elektroda, adrian1201, post #16647103]

Do I need an in/out code generator for this Focus VP44 pump?

No. For the VP44 on Focus MK1, adaptation proceeds without an in/out code generator; only the timed delay applies. [Elektroda, adrian1201, post #16647103]

Is the standard OBD2 connector enough, or do I need a special lead?

A standard OBD2 diagnostic connector was used in-thread. One user notes the task was performed via OBD using a KTS tool. [Elektroda, mbohun, post #17311151]

What if FoCOM fails during adaptation—what’s the fallback?

One user abandoned adaptation due to program issues and paid for immobilizer removal. Expect about 150 PLN if you outsource. [Elektroda, mbohun, post #17311151]

Does the model year change the code requirements?

Yes. Participants note that code behavior depends on production year, so plan accordingly before starting. [Elektroda, adam7009, post #16646671]

Were there successful real-world adaptations after pump replacement?

Yes. A member confirms completing several Focus pump swaps that adapted correctly afterward using diagnostic tools. [Elektroda, zubereq, post #16647335]

Can I do this with an ELM327 interface and FoCOM?

One user intended to try FoCOM with an ELM327. The thread does not confirm success or compatibility for this combo. [Elektroda, js83, post #17934689]

Does Transit 2.4 behave differently for this pump type?

An edge case notes Transit 2.4 may require in/out code generation despite a ~10‑minute window. Verify tool support first. [Elektroda, AuKElMe, post #16646303]

K‑line or CAN—how does FoCOM connect for this job?

The discussion contrasts K‑line vs CAN, but users completed the task through the vehicle’s OBD2 port in practice. [Elektroda, mbohun, post #17311151]

What’s a quick 3‑step how‑to for FoCOM pump adaptation?

  1. Connect FoCOM to the OBD2 port and turn ignition ON.
  2. Start the pump adaptation function and wait the ~10‑minute delay.
  3. Confirm synchronization, clear faults, and test start. [Elektroda, adrian1201, post #16647103]

Can a general scan tool like Bosch KTS handle this over OBD?

Yes. A user reports the procedure was “taken with KTS” via OBD, indicating capability with pro-grade scanners. [Elektroda, mbohun, post #17311151]
