Explore the fundamentals of onboard diagnostics (OBD) and learn how to diagnose various systems in the automotive engine, including gasoline engines and D-Link concepts.
Explore the origin and purpose of onboard diagnostics (OBD), its worldwide adoption for emission control. Learn how OBD monitors engines, fuel, ignition, and exhaust systems to alert drivers to faults.
Identify diagnostic trouble codes (DTCs) and the operating conditions stored by the onboard diagnostic system. Connect a standardized 16-pin diagnostic interface with a scan tool to diagnose and reset faults.
Explore enhanced manufacturer codes in onboard diagnostics for non-emission components, and the need for manufacturer software; learn the malfunction indicator lamp behavior, memory, freeze-frame data, and catalyst and evap monitors.
This lecture explains how the catalytic converter affects lambda and outlines onboard diagnostics monitors like misfire, fuel trim, secondary air, and oxygen sensor monitors, plus how to use OBD apps.
Diagnose engine oil consumption and leaks with compression tests, cylinder leakage checks, and ignition system inspection, identifying gasket, seal, exhaust, or head gasket faults and ignition wiring issues.
Explore spark plug diagnostics, including carbon fouling, oil deposits, insulation damage, and overheating causes, with a flowchart-guided approach to identify misfires and emissions issues.
Diagnose fuel injection by identifying symptoms like no fuel, hard starting, erratic idling, misfires, and power loss, using a flowchart to locate faults in injectors, pumps, timing, and idle control.
Diagnose lubrication issues by verifying oil level and service history, observing the oil pressure light at different speeds, and performing an oil pressure test for leaks and crankcase ventilation.
In the modern cars & vehicles, onboard diagnostics (OBD) have become as important and compulsory as the Automotive electronics. OBD has become a necessity to ensure even older vehicles are meeting the emission legislations. Learning about onboard diagnostics is very important in this twenty first century. The course elaborately addresses the below mentioned topics. Also the other courses authored by the same author also is added in the last video. The course also explains how any end user with the help of onboard diagnostic apps can easily figure out the various DTCs. Onboard diagnostics is a imperative part of the Automotive engineering
