Door Lock Problem (2012 Hyundai Sonata)

[@jakesautomotivediagnostics4405]

Got to be careful with latches that don't work and then work all of a sudden, a common problem can be wiring issues in the area between the door and the body where the wires flex with opening and closing of the door. Have been caught out with this issue before and paid for a new door latch when the fault was actually an open circuit problem. Wiggle test at the flex. :)

[@AllisonTheVegan]

Someone else told me to do this but how do you get to the wires in that part?

[@haywardsautomotive6156]

Nice diagnosis Tom and changing door lock actuators on Hyundai Sonata's are a pain with the module setup!

[@PositiveLeadDiagnostics]

You have to set them up? Looked like a boring old latch lol

[@haywardsautomotive6156]

Positive Lead Diagnostics The window regulator, door lock actuator, latch are all connected to the inner panel so you have to disconnect the window track just to get the panel pulled back to gain access to disconnect the o/s handle & door lock actuator link & remove door latch screws to remove it as a module...engineer needs to have his ass whooped

[@RAFICKDAMISONMOYO]

Thanks for the information

[@guayaco-dm3vu]

Nice one Tom.. I know someone would have thrown a module at it just because they would have guess and not believe 2 latches would go bad.. Only to find one out.One went bad early,customer didnt care for it.till second one goes...

[@DIETRYING001]

guayaco3299 love it when customers don’t tell you the whole story either, and when you question them for more information they seem to want to hold it back incase they think it’s gonna cost them more! Lol in reality it would cost them less to tell you what they can.

[@amr-50]

Great video man we missed your videos i hope to comeback soon .. thanks

[@EXOVCDS]

Nice to see that other manufacturers (besides VW) also have problems with door actuators! =)

[@PositiveLeadDiagnostics]

Yeah I was hoping for something better but hey this is reality lol

[@EXOVCDS]

I have a Euro Plate for you... send me your address.

[@PositiveLeadDiagnostics]

I just saw this sorry I’m late

[@bobbobby5724]

Fantastic video great to see you back.

[@roxanneabbott8424]

Always learning from you, thank you!!

[@StarTrekforever3698]

Thanks Tom, nice to see you doing videos again!

[@SuperMarioDiagnostics]

First! 😃 Good to see you back Tom, seems like every one is ultra busy lately 👍 good video bud

[@MajesticNISARG]

Fantastic video 💜💚❤️💙👍❤️💙

[@jeremieparker5703]

Awesome work Tom and a nice straight forward diag.. Keep up the awesome work Brother I would like to more from you

[@drbsr1948]

Good Job Tom..Always enjoy your videos

[@NewLevelAuto]

Well done sir. Good to see a new video from you

[@billrimmer5596]

New Level Auto I was looking forward to one from u the other day! Then it disappeared. Hope u r doing well. A 15 Fit gave me a fit. Alternator issues. But no battery light on the dash. Turned out to be a bad clutch pulley. Only 70 thousand miles. Factory reman fixed it. Couldn't find pulley separately.

[@rscelectrical7091]

Nice diagnosis bro.

[@billyyoder8171]

Thank you Tom. Good job. Appreciate your videos.

[@jgeorges3061]

awesome excellent way to approach and thanks for sharing MR Tom. cheeeeeers

[@Mmir2010]

Thanks, great video!

[@butchlewis7338]

So... What did you figure out? And what was done to fix it?

[@juweekhan]

nice video all the best

[@nicknicu1787]

Nice job Tom! 👍

[@tnamen1307]

Very nice info and would be more grateful if you could be specific on locating the lock and locking wires for all doors lock of the input connector of the BCM module? Thanks.

[@byoung9627]

Nice job on the video.

[@nelsonnarciso1791]

What brand are those wire pinch test leads and part number of you have .. Thanks.

[@nelsonnarciso1791]

Troy WT great thanks.

[@kenevans9849]

How do I get the door open to work on it? Seems impossible to remove the panel while the door is shut.

[@tnamen1307]

Very good information... Sir, could you show videos on i20 driver side window wiring diagram???? I'm very curious about the auto roll up window features of this car. Would be pleased to hear from you soon. Thanks.

[@m.chandranmaruthan9421]

Bro, is it possible to get a Hyundai Accent 2005 car central lock and alarm wiring diagran ?

[@throttlebottle5906]

heh, tha harnesses to the rear doors almost never break in them, the actuators break for sure, lack of overall latch usage and no lubrication lets them gum up and self destruct ;)

[@nithn313]

Please make a video for Hyundai i20 elite car front right door handle button doesn't work when pressed to lock/unlock

[@wyattoneable]

There you go. Verification is a good way to sleep well at night. :)

[@bryanlamontagne2914]

Tom, could you tell me where those relays are located on this vehicle?

[@GTS-Tuning]

hi tom, just a quick question. I understand the reverse polarity system. but i dont understand the purpose of the door lock unlock switch in the first diagram. ( in the box that says rear door lock actuator lh). what does that switch do? how does it relate to the motion of the motor. Because from what i can see the motor motion is dependent on the lock unlock switch in the second diagram that controls the relays. Basically if this makes it any clear, not sure what the purpose of the rear door lock/unlock signal from the ip junction is. Thanks for your help!

[@PositiveLeadDiagnostics]

I believe it’s just a switch position to tell the module if the door is locked or unlocked. In one position it will be a ground and in the other it will have a voltage on it

[@shaunsautorepairs5410]

Pity there wasnt a stored code for the locks. Then maybe you could see how long theyve been broken before they brought it to you. Im guessing one went bad a while back so they were using one rear door untill that went bad too..

[@damonroberts642]

How did you get the door open?

[@PattyKuluCakes]

Same problem with the 2012 Hyundai Tucson. All doors even the truck cannot lock/unlock all the way.

[@brandonfoss9445]

It would not have affected your diagnosis but this car has a door jam switch to tell if the door is open. Also the door latches on hyundai/kia vehicles do not communicate or have the ability to set codes. I've done quite a few on kia sorentos and they're all wired the same

[@PositiveLeadDiagnostics]

I’m used to Vw. Lol totally missed that it was old school

[@brandonfoss9445]

Positive Lead Diagnostics i hear you lol kia is my comfort zone

[@harsadmandan5403]

I am having the same problem with my car as well I got Hyundai i30 so I do I contact you pls reply

[@throttlebottle5906]

ahh, he returneth :))

[@tylercason6903]

Mine is doing the same thing but mine is the front driver side and the back passenger side how much is it to fix

[@momofmark2]

Hi, I have the same problem (front and back, passenger side). So, I don't need the actuators everyone is trying to sell me? Sometimes they work, and sometimes they don't, but even of they don't lock or unlock, they still click and move, just not enough. When it first started, it would only happen when the air temp rose above 98. I thought something had melted, and maybe it could be cleaned. But of course, the mechanic wants the $300 fix

[@PositiveLeadDiagnostics]

Sounds like a similar issue but without seeing it. It’s hard to tell

[@PositiveLeadDiagnostics]

Most likely you need both door latches. Simple voltage checks with a voltmeter will confirm for sure

[@moonsamygovender3916]

Where do I get those wire piercing probes?

[@PositiveLeadDiagnostics]

Aeswave

[@tnamen1307]

Sir my car i20 center locking system works only when locked from driver side. However, when locked or unlocked from passenger side, only this passenger door is lock or unlock respectively. The remaining 3 doors are not locking or unlocking!!!! Please help.

[@robertkramel8821]

What if the door lock module fails and the door is shut and will not open? How would you open the door to even diagnose?

[@PositiveLeadDiagnostics]

It may be a pain but sometimes you have to remove the door panel inside the car

[@robertkramel8821]

I had a feeling you would say that. Thanks🙂

[@ozzstars_cars]

Interesting how both failed. Wonder how long it was acting up?

[@throttlebottle5906]

quick, better make them can-bus linked magical computerized so ti can make 3/4 of the car not function, leave the owner stranded and let itself be stolen at whim :))))

[@damonroberts642]

In the one that is stuck in lock

[@rrmech11]

Nice beard

[@tamerajohnson4443]

CAN THIS BE CAUSED BY SLAMMING THE DOOR? THANK YOU

[@echo7mike]

Within 8 months, 3 of the 4 went bad in my '13. These cars and every part in them are absolute garbage!

[@Turbotomass]

door latches dumb stupid common issue. kia and Hyundai.
