| Langkah Uji Pemecahan Masalah | Nilai | Hasil |
1. Periksa apakah pemasangan konektor untuk ECM, J1/P1, J2/P2, dan J3/P3 sudah benar. Rujuk ke uji fungsional diagnostik Pemecahan Masalah, "Konektor Listrik - Pemeriksaan" |
ECM |
Hasil: Konektor tidak dipasang dengan benar. Perbaikan: Perbaiki masalah pemasangan. Kembali ke servis. Hasil: Konektor dipasang dengan benar. Lanjutkan ke Langkah Pengujian 2 |
2. Sambungkan Cat ® Electronic Technician (Cat ET) ke konektor alat servis. |
Cat ET |
Hasil: Cat ET tidak akan berkomunikasi dengan ECM.
Lanjutkan ke pemecahan masalah tanpa kode diagnostik Pemecahan Masalah, "Alat Servis Elektronik Tidak Akan Berkomunikasi dengan ECM." Hasil: Cat ET berkomunikasi dengan ECM. Lanjutkan ke Langkah Pengujian 3. |
3. Pecahkan masalah Cat Data Link untuk masalah yang mungkin. |
Cat Data Link |
Hasil: Cat Data Link tidak tersambung. Rujuk ke uji fungsional diagnostik Pemecahan Masalah, "Sirkuit Cat Data Link - Pengujian". Hasil: Cat Data Link tersambung. Lanjutkan ke Langkah Pengujian 4. |
4. Pecahkan kemungkinan masalah pada CAN Data Link (bila terpasang). |
CAN Data Link |
Hasil: CAN Data Link tidak tersambung. Rujuk ke uji fungsional diagnostik Pemecahan Masalah, "Sirkuit CAN Data Link - Pengujian". Hasil: CAN Data Link tersambung. Kembali ke servis. |
Jika prosedur tidak mengatasi masalah, hubungi Technical Communicator (TC) dealer Cat Anda. Untuk bantuan lebih lanjut, TC Anda dapat mendiskusikan dengan Dealer Solutions Network (DSN).
