| Langkah-Langkah Pemecahan Masalah | Nilai | Hasil |
|---|---|---|
1. Identifikasikan dan Perbaiki Hubung-Singkat A. Identifikasikan nomor konektor dan kabel sirkuit yang dicurigai.(1). B. Matikan sakelar kunci dan putuskan sakelar. C. Lepaskan komponen dan ECM dari rangkaian kabel. D. Atur multimeter digital terkalibrasi di kisaran 200 ohm. E. Hidupkan multimeter digital. F. Hubungkan konektor dengan kabel yang dicurigai rusak dengan sensor multimeter. G. Dengan sensor multimeter lain, periksa kontinuitas disepanjang semua kabel lain dalam rangkaian kabel yang sama. Periksa semua kabel untuk kontinuitas di sepanjang rangka atau ground. |
Resistan menunjukkan ≥ 5 Ω |
- OK Resistan menunjukkan ≥ 5 Ω. Rangkaian kabel tidak dihubung singkat. STOP Tidak OK - Resistan menunjukkan < 5 Ω. Rangkaian kabel dihubung-singkat. Perbaiki: Perbaiki atau ganti rangkaian kabel. STOP |
