Engine Management System

Penjabaran dari 9apps Engine Management System

This application informs and explains in detail about the engine control system and also comes with how to fix or solve problems with your car engine.
Precautions for On Board Diagnostic (OBD)
System of Engine
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the driver of a malfunction causing emission deterioration.
CAUTION:
- Be sure to turn the ignition switch OFF and disconnect the negative battery terminal before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will cause the MIL to light up.
- Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.)
- Certain systems and components, especially those related to OBD, may use a new style slidelocking type harness connector. For description and how to disconnect, refer to EL section, “Description”, “HARNESS CONNECTOR”.
- Be sure to route and secure the harnesses properly after work. The interference of the harness with a bracket, etc. may cause the MIL to light up due to the short circuit.
- Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM before returning the vehicle to the customer

Tindakan Pencegahan untuk On Board Diagnostic (OBD)
Sistem Mesin
ECM memiliki sistem diagnostik on board. Ini akan menyalakan lampu indikator kerusakan (MIL) untuk memperingatkan pengemudi kerusakan yang menyebabkan penurunan emisi.
PERINGATAN:
- Pastikan untuk memutar kunci kontak OFF dan memutus terminal baterai negatif sebelum pekerjaan perbaikan atau pemeriksaan. Sirkuit terbuka / pendek dari sakelar terkait, sensor, katup solenoid, dll. Akan menyebabkan MIL menyala.
- Pastikan untuk menghubungkan dan mengunci konektor dengan aman setelah bekerja. Konektor yang longgar (tidak terkunci) akan menyebabkan MIL menyala karena sirkuit terbuka. (Pastikan konektornya bebas dari air, minyak, kotoran, terminal bengkok, dll.)
- Sistem dan komponen tertentu, terutama yang terkait dengan OBD, dapat menggunakan konektor harness jenis slidelocking gaya baru. Untuk deskripsi dan cara memutuskan sambungan, lihat bagian EL, "Keterangan", "HARNESS CONNECTOR".
- Pastikan untuk merutekan dan mengamankan harness dengan benar setelah bekerja. Gangguan harness dengan braket, dll dapat menyebabkan MIL menyala karena korsleting.
- Pastikan untuk menghapus informasi malfungsi yang tidak perlu (perbaikan selesai) dari ECM sebelum mengembalikan kendaraan ke pelanggan
