Sir good morning I am auto electrician here in the Philippines will you help me to my work here I need schematic diagram of 2001 hyundai Santa fe diesel engine D4ea 4clender thanks for your time for me and GOD BLESS
Hi my friend. Yea, there is a temp sensor to detect the overheating, if EPS motor is overheating, its duty will be limited to 40 percent until it gets back to normal temperature.
In an older car with EPS in which the control module does not show up on a scan tool, how can a calibration be performed? Are there self calibrating units? All other control units show up except for EPS and even the FSM does not mention about EPS except for hydraulic PS. P/N is 28500 AN000. Excellent video, thanks.
Hi my friend. Generally when there is EPS system, we should have it one scan tool too. Sometimes you don’t see the calibration (as it used to be a manual calibration on some early versions) but you must be able to read the codes and live data. If you can see the EPS assembly but there is nothing on the scanner, there could be two cases, either your scanner doesn’t cover the software correctly, or EPS is aftermarket and someone had it installed. If car is too old (like the very early versions on EPS) there is a chance that calibration can be done using ABS system.
Дорогой коллега, снова классный и качественный видео материалы! Я хочу спросить,могу ли я перевести на другой язык ваш видео, и использовать только в учебных целях в учебном центре. С уважением ваш подписчик.
Hi my friend. Thanks for watching our videos. These videos are created exclusively for RUclips and only this channel. We are working on subtitles to add more languages, and hopefully your language can be one of them, so you can enjoy watching our videos with your language on our RUclips channel.
Great video. Just wondering how does the steering wheel turn when the power off? Because you can't transmit that turning motion back to the motor due to the screw gear. Is there some sort of slip clutch between the screw gear and the steering column? Thanks.
Hi my friend. mechanical steering will be still available. On the steering column (inside the torque sensor) there is a torsion bar which gets twisted when you turn the steering wheel (only less than 10 degrees), by this rotation, torque sensor detects the torque and direction, and EPS will assist. If torsion bar gets twisted but EPS does not assist, after that steering shaft keeps rotating and mechanical connection will rotate the steering pinion.
@@AutomotiveDiagnosis Ok, so that means the steering shaft is able to rotate even if the EPS motor does not rotate. I'm just wondering how they can disconnect when they need to. Thanks for responding.
Hi there, you can’t find the part in the part shops but you can install a good known torque sensor from another EPS assembly that was replaced for other problems. For example if there is any EPS with EPS motor problem, you can use its torque sensor, but EPS must be exactly same number.
Cool. I would imagine the motor changing direction would be by reversing the current. However, I noticed on the scan tool that the current did not change sign with the direction like the torque sensor. Is it just showing the absolute value? Is the motor changing direction while current is not?
Current value is absolute value. If it is a brush motor the direction is changed by H bridge controller(4 mosfet) via programming. If it is brushless motor, then direction is changed by switching the inverter circuit (6 mosfet) according to hall sensor value via programming.
Its all about programmjng. Torque value is calculated without |abs| value because to know the direction of turn. Suppose torque value is 2Nm. There is a lookup table. For 2 Nm suppose target current is 16A. Here current value is caluculated abs(current) so that PID controller can reach the current in any direction. In PID controller the target value is positive. Here current is the target which means how much power the motor will give.
At high vehicle speed, minimum assist required. At low vehicle speed max motor power is required. Its programmed like that. If driver apply too much effort torque sensor detect it and produces high motor power.
Problem they run dry and start creaking and very very expensive to replace if the body is worn out or cracked. Old ones on the steering column are more reliable
i am a 67 year old tech and the only cars that i can remember seeing without steering is back when i was in cub scouts and we raced pine wood derby cars - they had no steering. - before that, when i was 5 years old my dad had a little nitro powered model car, it was to be tethered to a spike in the ground with metal cables, you started the engine and let it go, it ran in circles until it ran out of fuel - it had NO steering !
Respected sir ,i have seen your vedio related abs in car.i am from india.my machanic said abs not working .he is saying brake fluid is not going to two wheels on right side.he said two things one fix a used abs or disconnet abs and put front brakes mannul mode.can i get information sir
He did not opened fully abs and checked sir.how can we say abs working or not.i went and said my brakes are not fully working .peddle getting stuck and car going left side when I brake.
Hi my friend, if brake fluid is not reaching to two wheels it could be from the relevant valves inside the ABS module. I don’t recommend to bypass the ABS, the best thing is to replace the ABS module if faulty
@@AutomotiveDiagnosis Thank you sir.my car is 16years Verna hundai car it's from my father who passed away in carona.from last two years I am using it.i already changed cluth plates and it's total setup .two years back they said we disconnect one wheel from abs problem.only three wheels for brakes.i did use well.56000kms used my father and now I used more 20000kms.now total 77000.now suspension problem and one mount problem due to vibration.which mount they did not checked.again now ABS problem.after company bill due to cluthes i stoped going to them.two years I managed by good mechanic from bihar.he gone away to his place.i am in hydrabad.yesterday I showed to new machanic .one said booster problem.another said abs because I said to him one tyre brake not working.then he worked good and checked.no fluid to two right font and back tyres.then said Abs because I ready said before to him.he said he will try second hand or not mannul front two brakes.i said we will go front two mannul brakes .because of low cost.yesterday day night i couldn't sleep and searches vedios of you.i thank God for you to your replay sir. .i couldn't have money to invest new car or to put more money 16yeras old car.i am managing and happy because my father remembrance.i woke early and saw any reply for my message .no body give back .but I saw your message and felt so happy and God bless you so much .
@@wakeupvamsi5950 My condolences to you my friend. Have you or your mechanic checked the master cylinder? I'm asking because you said two wheel are not braking. Master cylinder provides two hydraulic pressure through two brake lines which both go to the ABS module. Each of those two brake lines provides fluid for two wheel (which happens through the ABS module). Also inside the ABS module there are two pistons (primary and secondary pistons) if any of them fails, hydraulic pressure from that piston will stop, causing no brake in two wheels.

Very interesting, thank you! I have EPS in my Opel Corsa from 2003. I have had DTC for overheating when my wife practicing parking....😀
Hi my friend. Overheating code is normal when EPS works a lot under the high torque.

what scanner did you use to calibrate the loop ?

They are very efficient, aren’t free of faults though.

i thought its hyundai,this part is one of the expensive part to replace.
Yeah, it’s very similar design and of course very expensive.
Which car has steering?
i am a 67 year old tech and the only cars that i can remember seeing without steering is back when i was in cub scouts and we raced pine wood derby cars - they had no steering. - before that, when i was 5 years old my dad had a little nitro powered model car, it was to be tethered to a spike in the ground with metal cables, you started the engine and let it go, it ran in circles until it ran out of fuel - it had NO steering !
This EPS was from a Mazda, but many cars these days have EPS with very similar design.

Whatever you call “torque sensor” is looking pretty much as rotary encoder.
Hi my friend. It’s actually like a rotary encoder but as many companies call it torque sensor, I go by that name
Some units have a rotary encoder, but they all have a torque sensor that measures the twist of the shaft as force is applied when the wheel is turned.
Yes, bcoz this is rotary encoder. EPS module calculate speed and rotation angle same time.
