Self-diagnosis of a Hyundai car without the use of computer equipment
Hyundai error codes are considered for the following car models:
10 This code on Hyundai machines indicates an increased pulse recorded in the electrical circuit of the mass air flow controller
13 Air pressure controller failure
16 Pulse from airflow pressure regulator out of range
19 Too low input pulse on the power wire of the flowmeter
Malfunction of the climate control system, possible causes of failure:
breakdown of the relay of the air conditioning system;
clogging of the pipes through which the coolant circulates;
violation of tightness or damage to one of the lines of the air conditioning system;
malfunction of the climate control unit;
failure of the compressor device or its incorrect operation.
22 Increased signal on the airflow pressure sensor line
25 Failure or poor connection of the intake air temperature controller
28 Inlet temperature sensor pulse out of performance range
31 Reduced signal fixed on the intake temperature sensor line
37 Faulty antifreeze temperature controller
40 The coolant temperature sensor gives an incorrect signal to the engine control unit
49 Throttle position controller failure A
61 Antifreeze temperature too low for closed loop control of the cooling system
82 Faulty second oxygen controller installed in the first bank of the engine
97 Failure of the heating component of the second oxygen regulator located in the first bank
Self-diagnosis of a Hyundai car without the use of computer equipment is performed as follows:
Error reading example: code 0102 consists of 10 fast blinks, then one blink, ten flashes, two blinks and a pause. After the control unit issues all errors, their output will start again, in a circle. The ignition system can be turned off.
Hyundai diagnostics using a computer will show a more accurate result, unlike the self-test method. But to implement this method, the user will need a laptop with a good battery (if there is no outlet in the garage), as well as special software. If possible, a special scanner can be used, but such equipment is usually only available at specialized service stations.
Checking using a computer is performed as follows:
How to reset the error?
It is necessary to delete the error code from the memory of the control unit only after the malfunction has been eliminated. Otherwise, the code will be erased, but the problem will remain.
The reset procedure is as follows:
Before performing the task, you must turn off the ignition system for at least 10 seconds.
Then the key is scrolled to the "ACC" position. Without starting the engine, the user needs to count three seconds.
Over the next 5 sec. the gas pedal is squeezed out five times until it stops on the floor. After the last press, seven seconds must be counted.
Then the gas is again squeezed out to the floor. The reading of the fault code will begin, at this moment the user must press the pedal all the way and release it.
The ignition in the car is turned off, after which the power unit is started. Information about the error code should disappear from the memory of the control unit.
If diagnostics are performed using a computer, then an easier option to erase errors is to delete them through the program. The utility has a special menu for resetting the memory of the control unit.
