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
- VP44 pump adaptation uses a ~10‑minute security delay before pairing completes. [Elektroda, adrian1201, post #16647103]
- No in/out code generator needed for VP44 on Focus MK1 during FoCOM adaptation. [Elektroda, adrian1201, post #16646481]
- Several Focus 1.8 TDDI units were successfully adapted after pump replacement. [Elektroda, zubereq, post #16647335]
- Procedure can be initiated via the standard OBD2 diagnostic connector. [Elektroda, mbohun, post #17311151]
- Some model years handle codes differently; requirements may vary by year. [Elektroda, adam7009, post #16646671]
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]
How long does the FoCOM adaptation take?
Plan roughly 10 minutes for the security delay, plus a few minutes to initiate and confirm the session. [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 is FoCOM?
In this context, FoCOM is the diagnostic software users employed to initiate pump adaptation on the Focus 1.8 TDDI. [Elektroda, adrian1201, post #16647103]
What is a VP44 pump?
VP44 refers to the electronically controlled rotary fuel pump used here; the thread’s guidance targets that specific unit. [Elektroda, adrian1201, post #16647103]
What’s a quick 3‑step how‑to for FoCOM pump adaptation?
- Connect FoCOM to the OBD2 port and turn ignition ON.
- Start the pump adaptation function and wait the ~10‑minute delay.
- 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]
