iOBD2 Diagnostic Tool for iPhone with WIFI

iOBD2 is a vehicle diagnostic tool for iPhone, and it communicates with these smart phones by WIFI. It supports OBDII/EOBDII. It records the data by the client software of the phone. It records data like engine speed, ignition time, fuel correction, fuel consumption, coolant temperature, when you are driving the car and it shows these data by form or graph format.


iOBD2 Diagnostic Functions

Clear DTC
Read data stream
Read freeze frame data, vehicle information
Oxygen testing
Mode 6 testing
Evaporative Emission System Leak Detection

My Dashboard

Idle speed mode: control the voltage, intake air flow, real time fuel consumption (static), coolant temperature, spark advance angle, engine speed
Cruise mode: vehicle travel time, average speed, continuous running mileage, average fuel consumption, vehicle speed
Sport mode: vehicle speed, coolant temperature, real time fuel consumption (dynamic), acceleration, engine speed. It is with rich user experience.

Troubleshoot Vehicle Overheating Engine

Overheating engine is commonly seen in automotives. What is the reason? How to troubleshoot?

Obd365.com informs you to inspect 5 vehicle parts to troubleshoot overheating engine.

1. Inspect Engine Coolant Level, Test for Leaks and Test Radiator Cap
Why should inspect on engine coolant level, test for leaks and test radiator? The reason is that coolant functions on transferring heat from the engine to the radiator, if lack of coolant or leakage of coolant, the procedure will malfunction, leading to overheating on engine. Overheating problem may affect the performance of radiator and coolant reservoir. Milky oil condensation in the engine will lead to failed cylinder head after you have cap removed to examine.

Tip: make sure proper engine coolant level and no leakage. If necessary, repairs or refill system should be done.

2. Inspect Engine Thermostat
Thermostat is used to regulate the flow of coolant from the engine to the radiator. If car thermostat malfunction, coolant flow stick closed will be stopped and overheat.

Tip: replacement is needed when the water has boiled and the thermostat valve is still closed the thermostat has failed.

3. Check Engine Cooling Fan Clutch or Electric Fan Operation
The cooling fan system works to move air through the radiator, so it fails to work, it will lead to engine overheat.

Tip: be noted to turn ignition off before start check it

4. Low Flow through Radiator
Radiator in a car is designed to remove heat from the engine coolant through convection.

Tip: replacement is necessary if he radiator cooler tubes are plugged drain the cooling system completely.

5. Plugged Catalytic Converter
Catalytic converter is one of the main emission control device in a car, high temperature in it wil crack and come apart clogging the outlet port of the converter causing, engine overheating, low power and stalling.

Tip: if a car is equipped with more throttles, it will create more heat for cooling system; if it exceeds to its capacity, overheating engine exists, and even accompanying with low engine power.

What is the reason of overheating engine?
Various reason lead to overheating engine, but all the reasons mainly because of cooling system failing to remove heat away, lack or low level of coolant and overload or create too much heat to engine.

Therefore, troubleshooting overheating engine should be careful of coolant, and the limited capacity to a car engine.

Diagnose GM Ignition Control Module Problem

The most important Tuirel S777 part of a vehicle's ignition system, including a GM vehicle, is the ignition control module because it regulates all aspects of the ignition, including the spark plugs. Mechanics use a special diagnostic scope to identify any existing problems within the ignition system, but if you do not have a scope, there are ways to visibly troubleshoot components of a GM vehicle's ignition system.

No Lubrication

Grease or silicone should always be present on modules that are in good working condition to prevent the penetration of heat through the module's surface. Inspect the module for a visible layer of grease or silicone on the back of it. If this film is absent, the module needs to be replaced.

Irregular Spark NEXIQ 125032

Install a timing light and monitor the engine for an irregular spark while the light is operating. If you notice an abnormal spark, but the spark plugs do not look damaged, the ignition module may be faulty.

Cracks

Any cracks or damage to the module's surface indicate a problem. Remove the module and inspect it for damage or cracks on the surface or around the mounting screws. If there is any visible damage, replace the module.
