AD55B Underground Articulated Truck Power Train Electronic Control System Caterpillar


MID 027 - CID 1401 - FMI 11

Usage:

AD55B JNW
Kondisi-kondisi yang mendorong penciptaan kode ini:


Ilustrasi 1g01403658
Skematik Solenoid Transmisi 1

Kode diagnostik ini terkait dengan solenoid transmisi 1. Kode diagnostik ini dicatat bila Modul Kontrol Elektronik (ECM, Electronic Control Module) Power Train/Chassis mengidentifikasi bahwa ada beberapa pengidentifikasi mode kegagalan (FMI, failure mode identifier) yang bertanggung jawab atas satu masalah atau saat FMI tidak cocok dengan kategori lainnya.

Kemungkinan penyebab kode diagnostik ini adalah

  • ECM mungkin mengalami kegagalan internal.

Tanggapan:

Saat kode diagnostik ini aktif, indikator peringatan kerusakan transmisi akan berkedip. Selain itu, lampu tindakan akan berkedip dan alarm tindakan akan berbunyi. Transmisi akan berpindah ke posisi NETRAL dan rem parkir akan diaktifkan setelah 5 detik. Caterpillar Electronic Technician (ET) tidak akan dapat mengontrol solenoid. ET akan membaca tegangan sirkuit solenoid berada di bawah normal, yang merupakan indikasi adanya sirkuit terbuka. ET tidak akan dapat mengalirkan energi ke solenoid.

Referensi: Untuk informasi tentang mode limp home, rujuk ke Pengoperasian Sistem, Pemecahan Masalah, Pengujian dan Penyetelan, "Kerusakan Solenoid Transmisi".

Langkah Pengujian" status="1 1. PERIKSA ECM

  1. Putar sakelar start kunci dan sakelar pemutus ke posisi MATI.

  2. Tunggu selama 30 detik.

  3. Putar sakelar pemutus ke posisi ON.

  4. Putar sakelar start kunci ke posisi ON.

  5. Tunggu swauji berakhir sebelum Anda melanjutkan ke langkah berikutnya.

  6. Periksa apakah ada kode diagnostik aktif.

Hasil yang Diharapkan:

Kode diagnostik CID 1401 FMI 11 tidak lagi aktif.

Hasil:

  • YA - Kode diagnostik CID 1401 FMI 11 tidak lagi aktif. Me-reset ECM berhasil mengatasi kode diagnostik.

    BERHENTI

  • TIDAK - Kode diagnostik CID 1401 FMI 11 masih aktif. ECM gagal.

    Perbaikan: Kemungkinan ECM gagal sangat kecil. Keluar dari prosedur ini dan lakukan kembali prosedur ini. Jika penyebab kode diagnostik tidak ditemukan, ganti ECM. Rujuk ke Pengoperasian Sistem, Pemecahan Masalah, Pengujian dan Penyetelan, "Modul Kontrol Elektronik (ECM) - Penggantian".

    BERHENTI
