diagnose dan fix it again!!!!!!! you are awesome!!!! been a tech. for 48 yrs. now still learnin, i think of you as a good ol boy!!! a.k.a. ...for you non-country folk...=friend!!!!! thanks again!!!!!!!!!!!!!!!!!!!!
I am mechanic, I have and I have similar issue but unfortunately, my own the signal wires found tight between the lower arm bolt and the touch each other to the flame, the wire are fixed but still the light is on and the steering is hard, can it be fuse or what, please help me out
I'm pretty sure that the bad ground (high resistance, low current flow) Didn't cook the module. You would need excessive current flow which you dont get from high resistance. Great video tho keep em coming
Diagnostic Check, try to jumpstart a car using a speaker wire, it will work but it creates a lot of heat in the wire and the wire would eventually fail. There was no ground on the Eps but still there was enough current flow to raise the voltage in the flexray wires.(It did not even light the test light). And the electric motor was not working at this point. Now imagine the point where the Eps was still working but the ground was starting to get bad.
DiagnoseDan does starting a car with a speaker wire damage the starter motor in any way? I don't think it does due to there being a voltage drop/less current flowing. When has a bad ground/live EVER caused the component designed to be in the circuit to fail?
Diagnostic Check if the path to ground is through a pcb that can’t handle the excess current flow it will burn, no? The way I understand it the motor wasn’t burnt, the module on the motor was toast
Diagnostic Check, there is no arguing with a RU-vid provider trying to make a dramatic or shocking point. He's making egregious claim like you can run enough current through speaker wires to turn a starter. It just not going to happen.
did that wire have a flex issue or did it just root , no pun intended on the flex thing .... looks like another one to add to the books of knowledge on preventitive maintenance ....
Mijn power steering werkt ook niet… Als ik de hoofdstekker verwijder van de EPS (2 dikke kabels) en daar de spanning vanaf meet, komt er tot mijn verbazing geen spanning uit. Zekering nagekeken en deze zijn in goede conditie. Wat adviseer jij? Zijn er wellicht ook printplaatjes die het kunnen begeven? Ook geeft hij geen foutcodes aan..
My electric motor is making noise when i turn on my ignition. When I unplug 3pin plug its goes off. What might be the problem? Both thick wires have its ground and power
Sir l have Skoda Laura car & it's powe steering not working ( hard). Error on dashboard is Red steering. So pls suggest me to what can I du for this problem to restore it.
Hi Dan, yesterday as I was pulling in a parking lot after driving in very heavy rains I had a snapping sound from underneath the car and 2 - 5 minutes later the steering light popped up and I totally lost power steering.. What could be the problem?
I have the same problem, turn on the steering pilot, the errors are: 0x4823f1 / 0xd5c44 / 0xd552c79 ,. I already checked the current on the servo motor is very well, signals are also ok, I checked the fuses ok, but the pilot does not go out.
hey i have a F25 and it has a similar problem, when you just turn the car on the power steering doesnt work for the first couple mins but then after that works like nothing, I havent been able to find out whats the problem with it.
My F25 2011 year，It’s just the opposite of your car’s symptoms. The EPS was working normally within 10 seconds of starting the car, but suddenly it lost power steering and showed a fault light, then it didn’t work, and the steering wheel was very heavy. Have you found any problems with your car? Has it been fixed? thanks
Hi everyone, I have a 2010 BMW E90 (320i). I have a problem with my steering system, which is similar to this. When I try to park the car, on low speed, whenever I rotate the steering wheel near 180 degree, steering becomes heavy for couple of seconds, and it becomes normal if I put gas to move the car to help it. I also noticed when I experience this, my headlights as well as cabin light starts to flicker. Flickering gets more apparent if I rotate left and right constantly to test. Initially I suspected alternator and battery, but they are all okay. In this case, do you think my problem is related to cables/wiring? In my car fault history, I have below codes; 5E19 ABS-DSC: CAN data fault from DME/DDE (DSC lamp on as long as error is present)" 5D97 DSC: Control module: power supply, DSC sensor 5DF7 DSC: System voltage too high I would really appreciate if you could advise me on this.
I have no experience with BMW cars. I work only on PSA cars. My question is : this BMW have Flexray in place of High speed CAN? What is the speed of a Flexray system? My scope works just good enough for H.S. CAN. Will my old scope be capable for Flexray? Thank you for the video, Dan.
Can u told me after disconnected the steering rack power supply motor need to do EPS start up ? How? U do? Pls help to tell me Pls in BMW f45 /218i , can I have yr WhatsApp pls help..
Hi, i want to thank you a lot for you vid mate, my E90 had EPS failure and thanks to you i checked the ground wire, it was all dirty so i just cleaned it and since 3 days everything works well again. I would never had guess this problem without your help. Keep it on !
Good video Dan,. Good old fashion "VD" voltage drop. I do think Flexray is going to be used for all new vehicle's, and for autonomous applications via ADAS. Flexray speed is 20Mbit/sec through the gateway into the ADAS system and steer by wire systems all we have to do for the limp home mode for that situation is get the computer to turn on your four-way flashes cuz you're going to be coming to a fast stop. With the LIDAR system and ADAS it'll be able to pull you over fairly easily having 360° view of all surroundings.
Truly enjoy your very informative CAN Buss theory and troubleshooting procedures. You and Keith Defazio are the best. Most problems caused by sloppy wiring. Cheers Dan
Hello Dan Excellent vidéo, I Just discovered your channel and you do an excellent work and teaching about your work I need your help please with my 2012 f30 328i EPS I had 2 default codes 48239C EPS torque sensor (steering angle index): Index Faulty D01B2A Interface EPS (actual position EPS 51.0.2): Signal invalid And im completely lost, no one could résolve my problèm i've changed my eps 2 times it resolves the problème for about à month only Please help 😢
Awesome video Dan! I used to see "fried ECU's" on mk2 VW's due to a bad battery ground cable going to the transmission or people not attaching the cable after a clutch replacement (starter tries to ground through the ECU). Dan Sullivan's "LoadPro" in action... with no royalties going to him. =( (I hope I have my facts right... my apologies if I don't).
Thomas EXOVCDS positive voltage will always try to find a way to ground, when a big ground cable is bad the current can start to flow thru a smaller cable or circuit that was not designed to carry this current ( like blowing a fuse) the circuit can become overloaded and fail.
DiagnoseDan On older vehicles, if I see a high O2 Sensor reference / bias voltage, I check the grounds for the ECU. I will have to keep this in mind for other modules / systems! Thanks again, great video!
Thomas EXOVCDS if a voltage is higher than you would expect always check the grounds! It is almost 7 in the morning here i guess it's bedtime in Canada😂
I want to learn more! Nice repair. I would have covered the bare terminal with silicone sealer. This connection is in the path of corrosive elements, bad choice on BMW’s part. Solder and heat shrink is the only option for any permanent repair. Here in America, the majority of mechanics think it is proper to use crimp connectors and call it fixed.
Had a similar situation with a g12 at work, flex ray communication faults and all but it just ended up being the power supply wire being pinched and ended up causing on open in the circuit
I found something similar to this on a VW Tiguan, no power steering assistance and no communication. It had corrosion on the ground besides the battery, just cleaned it and it worked instantly.
Dan you have saved me a fortune. Had the exact same problem as in the video. Checked the earth and it fell off in my hand. Jump lead from the earth lead to ground and the power steering worked again!!! Thanks 👍
Hello, I think I have a problem with the abs modules, no errors or lights come on, the symptom is and when I turn on the windshield above 120kmh it stops, losing around 20kmh, could it really be the abs module? When I deactivate drybranking through coding it doesn't help me but I feel the car is a little stuck at the speed level, thanks for the answer, hugs from Portugal
To whom it may concern, my name is Joe and I own a 2015 Bmw 750li xdrive. I was using the protool to code my car and i believe i made a mistake of testing the Flexray option and gave me so many errors and lights on the dashboard. After clearing the codes and restarted the car, Night visiont camera, both side mirror camera and backup camera stop working. I am in desperate need of advice on what i should i do. I tried pretty much anything i could with the protool app. Restore the cameras to factory settings, and still didn't work. I would absolutely appreciate any advice and help i get. Thanks in advance. Joe G
This type of power steerings are such a pain... 1st I replaced the electric steering pump on my fiance Fabia and I thought that was expensive, but then my 2010 Passat has a similar steering rack fried and I still didn't change it, and now my mom's E87 2010 which I think has the exact steering rack like the one in the video, gave EPS: Steering torque sensor error but somehow after I cleared the code it's working and I hope it will not break because it costs a ton of money, almost double than the Passat one. I wonder if there are parts available for this racks like dc motors and sensors.
thankyou dan for the upload. So the voltage was elevated in flexray wires because of bad ground. where did you put ground connection while taking measurement in scope ?
Ik heb dit juist voorgehad met mijn F30 (2012) Heel plotseling ook, auto 's avonds geparkeerd, 's morgends willen vertrekken en geen EPS meer. Kwam er nog bij dat mijn RPA systeem uitgevallen was en mijn tractie controle, staat dit in verband met elkaar? Ik moet er ook wel bij vertellen dat ik 2 weken voorheen een nieuwe dashbord cluster (instrumenten paneel) heb moeten laten vervangen omdat alle indicatie lampjes begonnen te flikkeren. Ik heb wel niet dezelfde met het kleine digitaal schermpje maar een 6WA met het het grotere digitaal scherm laten installeren met een extra MOST kabel om de boel te doen laten werken. Goeie video trouwens, als ik mijn wagen terug heb ga ik dit eerste werk nakijken, beter nog laat de garagist dit filmpje zien en we kijken het samen na
is a big day for me my car is n52 on the morning my steering is to hard to turn if i accelerate 3000 rpm is seen like. good the mechanics ask to me need change whole thing but i don’t 5 month always like that thanks to uploaded this video
