Error codes that occur during the operation of the equipment can be calculated using a computer. There is also an alternative method using a warning light called the Check Engine.
Instructions
Step 1
Prepare the vehicle for diagnosis. Turn the operating mode selector counterclockwise as far as it will go. Turn on the car ignition. Turn the selector knob clockwise until it stops. After that, proceed directly to the diagnosis.
Step 2
Read error codes with a warning lamp. Errors are recorded in the memory of the control system of Japanese cars; to retrieve information, it is necessary to close certain contacts - E1 and TE1 in the diagnostic socket. Usually its name is displayed in the form of markings applied to the body.
Step 3
To read the error code recorded when using an ITMS-6F microcontroller, short-circuit contacts A and B, turn on the ignition and view the result. This type of microcontroller is usually used in VAZ-21213 cars.
Step 4
If you do not know where the diagnostic compartment is located in your car, find it in the engine compartment or the passenger compartment. Everything here may depend on the model of the car you have. If you cannot determine the name of the contacts in the block, be sure to read the literature regarding cars that are similar to yours in terms of internal components.
Step 5
Please note that each error code is displayed only three times, after which the system shows a new one. In the case when code 12 is displayed, this indicates the beginning of the diagnostic procedure. If it is not indicated, most likely, the diagnostic system is in a malfunctioning state.
Step 6
Please note that in many new model cars, diagnostics is only possible using a computer equipped with a specially designed K-Line adapter. If you need to clear the computer memory of error records that have accumulated over a certain period of time, just turn off its power and remove the terminal from the battery for a minute.
