   • Tsofaffin tsarin: Lambobin gabaɗaya (misali, "E30" don kurakuran sadarwa).

   • Tsarin zamani: Cikakkun lambobi (misali, "CAN Bus Timeout" ko "RS-485 CRC Error").

2. Ba da fifiko ga Warewa Sigina:

   • Misali: Lambar "Rukunin Rukunin Rukunin Rukunin Rukunin Rukunin Rukunin" yana nuna matsalolin bas na CAN, yayin da "Lokacin Kiran Zaure" yana nuna kuskuren RS-485.

2.2 Duba Ƙarfin & Layin Bayanai

Binciken Mahimmanci:

1. Gwajin Ci gaba:

   • Yi amfani da multimeter don tabbatar da ingancin waya. Don dogayen igiyoyi, ƙirƙiri madauki tare da madaidaitan wayoyi don ma'auni daidai.

2. Juriya na Insulation:

   • Auna tare da megohmmeter (> 10MΩ don RS-485; > 5MΩ don bas na CAN).

   • Tukwici: Babban sigina na mitoci suna kwaikwayi gajerun da'irori idan rufi ya lalace.
