Caterpillar Electronic Technician (ET) digunakan untuk memuatkan file trim injektor ke Modul Kontrol Elektronik (ECM, Electronic Control Module).

File trim injektor harus dimuat ke dalam ECM jika salah satu kondisi berikut terjadi:

  • Injektor diganti.

  • ECM diganti.

  • "Injector Trim" (Trim Injektor) ditampilkan di bawah kode diagnostik 268-02 pada Cat ET.

  • Injektor dipertukarkan di antara silinder.

Mempertukarkan Injektor

Mempertukarkan injektor dapat membantu mengetahui apakah masalah pembakaran terletak di injektor atau silinder. Jika dua injektor yang saat ini terpasang di engine dipertukarkan di antara silinder, file trim injektor dapat juga dipertukarkan. Tekan tombol "Exchange" (Tukar) di bawah layar "Injector Trim Calibration" (Kalibrasi Trim Injektor) pada Cat ET. Pilih dua injektor yang akan dipertukarkan dan tekan tombol "OK". Tattletale untuk injektor yang telah dipertukarkan akan meningkat sebesar satu.

    Catatan: Nomor seri injektor dan kode konfirmasi injektor terletak di injektor. Cat ET mungkin membutuhkan entri kode konfirmasi injektor selama proses ini. Cat ET akan meminta kode bila perlu.

  1. Catat nomor seri injektor dan kode konfirmasi injektor untuk setiap injektor.

  2. Klik "Service Software Files" (File Perangkat Lunak Servis) di SIS Web.

  3. Masukkan nomor seri untuk injektor di bidang pencarian.

  4. Download file trim injektor ke PC. Ulangi prosedur ini untuk setiap injektor bila perlu.

  5. Sambungkan Cat ET ke konektor alat servis. Rujuk ke pemecahan masalah elektronik Pemecahan Masalah, "Peralatan Servis Elektronik".

  6. Pilih opsi menu berikut di Cat ET:

    • Servis

    • Kalibrasi

    • Kalibrasi Trim Injektor

  7. Pilih silinder yang sesuai.

  8. Klik tombol "Change" (Ubah).

  9. Pilih file trim injektor yang sesuai dari PC.

  10. Klik tombol "Open" (Buka).

  11. Jika Anda diminta oleh Cat ET untuk memasukkan kode konfirmasi injektor ke bidang tersebut.

  12. Klik tombol "OK".

    File trim injektor dimuat ke ECM.
