2010 Mercedes Benz GLK350 where the Instrument Cluster had been replaced before and the mileage doesn't display... I lost count of how much time I had involved in figuring out how to correct this issue.
*I did a few mileage corrections on Mercedes cars. If the SSID number of the cluster was correct, when the cluster was plugged to the car, it would have sync itself with the EIS and the one of the two (cluster & EIS) with the highest mileage will win. For example if the EIS had higher mileage, the cluster would have taken that mileage and visa versa. The reason the dashes were there is because the SSID was wrong. Well done!!!*
Good one! Glad you got it figured out. I'm betting if you would have just blanked out the mileage portion of the data with the correct hex for zero (either ff or 00) then corrected the ssid and installed it, the eis would have shot over the mileage into the cluster and you would have been ok. I say this because I had a similar situation with a BMW that I got it working in this way. I learned a lot on mine and I bet you did too here. Thanks for sharing as always.
Dang must have been soooo satisfying to see the mileage finally show up on the cluster!! I like cars with analog odometers...maybe replace the worm gear if they stop turning haha
@@autodiagytI do the same thing. I may spend a little longer than I should on something like this but it feels good to tell that guy that everyone has told no or that it can’t be done that you fixed it. You can quickly make a name for yourself in your area as the go to guy that way.
Jake that is awesome how you were able to research the problem and then go into the eeprom and read all the hexadecimal data and write the appropriate data back into the chip. I don’t know if you learned all knowledge on your own or went to a class for it but you are one heck of a diagnostic technician. 👍Artie
@@autodiagyt so glad to have joined your you tube. Yes I’m older but I will never stop trying to learn. Your channel plus a few reputable others plus joining groups like Hands on Automotive with Brian Mann, Mechanic Mindset with Darren Quinn plus a few programming groups are very helpful. Individuals like yourself that show the whole process from good to bad are very few. Nothing is ever easy and perfect I just keep putting in the time. Thanks for replying Jake 👍
Someone must be riding that brake pedal to have that much wear. When I sold my last S-class it had 278,000 miles on it and there was no real visible wear on the rubber pad. I’m constantly amazed by your knowledge and skills.
Very interesting case and great work around, Jake! Some time back, I saw a channel in YT that deals with this kind of stuff and decodes / encodes the hex data in the EEPROMs - although they explain a lot about data location and contents, they are a commercial project, that sells in-circuit readers and software. Can't remember the channel name, though. Your problem was the exact opposite of a funny case a friend of mine told me, some 15 years ago. He worked as a car electrician in a specialized shop and the owner bought a cheap Mercedes in mint condition, but it had too many miles on it. So, he decided to buy a new cluster (very expensive), thinking he could program the mileage in it, but the moment he connected it, it updated to the real mileage :-) Apparently, that Mercedes (can't recall the model) had the mileage stored in three different modules and self-corrected any discrepancy among the three stored values.
Sounds like Andromeda Research. They have quite a few RU-vid videos on eeprom work and they sell a great programmer that does in circuit work where others can’t. Their programmer has dip switches to change the voltages and such so that it doesn’t wake up other components that are connected to the eeprom that have a tendency to corrupt the data you are trying to read/write.
Great job! Also have an IM608 but since it messed up couple important EEPROMs during reading/writing never use it for the important immo jobs anymore. For programming Asian smarts only) Came back to VVDI and never regret. BTW it messed up EIS chip data when I was trying to read original data and I was f..ed.
Make sure you go into the options in the eeprom menu on the im608 and turn on the option to validate the reading and writing of eeprom data. It will double check every read and write so you’ll usually know if you had a bad read as it certainly happens especially if you’re trying to do it in circuit. The good thing is that if you’re not getting a good read from the chip the data will never be the same when reading it twice and the validation will usually catch that. The menu you’re looking for is on the menu where you have the read eeprom/write eeprom after you have selected what chip you are working with. I never mess with voltage selection I just turn on the validation options. Changing the voltage setting could help to get a good read in circuit but I usually go to the AR32a in those situations anyways as it’s a great in circuit programmer.
Jake, this is pretty heavy duty stuff! I don't think normal people think about this kind of thing. But some of us aren't normal. This was fun! Thanks for Sharing! 🤔🙂🙂
Great information, thank you. Really appreciate you taking your time and explaining the process of doing that kind of work. 👍 I'm still learning eeprom work, so every little information helps me out.
I have very good luck reading in circuit with the Andromeda Research Labs AR32A. It built for reading in circuit. If you’ve never used one you should give it a shot. I don’t mind desoldering chips but I would much rather not have to do it and save time in the process. You do need a laptop or computer with a serial port to use it.
Didn't know Autel had PC software for the XP400, I guess I missed that. Would that be the ATProgrammer/XP400 software? I got the 608 Pro II when first released, wanted the faster CPU and more memory.
Im also have this problem. I changed my w221 instrument cluster one month before. Now my milage like this. -------- and have a drive authorisation fault for the instrument cluster. I have maxisys 909 tool can i change my actual milage from that tool.??? Like re program or learn drive authorisation, without remove any parts ?
Enjoy your weekend with all your family around you, Automotive Diagnostics & Programming, 👍 SHARP Automotive Diagnostics & Programming From Nick Ayivor from London England UK 🇬🇧 ⏰️ 22:29pm
yes but the mileage could be a million miles on the key module five miles on the dash if they came from a different car how are you to find the true mileage of the car they are in now if any module that holds any mileage dont belong to the original car in the uk police cars dont have a official mot inspectoin so that car could be clocked and loose hundred thousand miles and no way of checking and cannot go to last mot to check @@autodiagyt
thanks for the reply i am suspicious when mileage is different i look for outside 3rd party confirmation i have seen a lot of clocked cars @@autodiagyt
I really can't remember what all I had to do but I don't think I could do it on bench with just the 2 modules. I'm sure someone that does a lot of Mercedes probably could but I don't know that I could.
@@autodiagyt ok thank you for your reply. I’m hoping I can find someone because the dealer will definitely empty my bank account on this one I have a feeling. Dave,,
4:30 I'm screaming just pull the EEPROM read it from the old cluster & get EIS data open both in a hex editor mod, save & write back to EEPROM, I'm a mechanic & electronics tech 40+yrs this is basic shit, no offense but I flash 1-2 lapotop bios chips every night & at least 1 ECU a week for so many different reasons so don't ask cuz the answer is stupid but I do as I'm asked to do with no diag & 1. I get paid upfront & 2. It usually doesn't fix said problem & that's when I say do yo want it fixed........$$$$$
Yes but the EIS had the required data to open in a hex editor to add to the file from new the cluster EEPROM the thing is knowing what to cut & paste in a HEX file if you can't read them, anyway not anyways that's a yank thing the young n dumb in OZ say & I just shake my head n say society is F-ed if that's our educated failures, yhanks social media of which I want no part.
@autodiagprogramming I definitely understand that just always been very interested in that type of work I've always been interested with coding I've also been very interested in circuit board designs and functionality and and repair of the circuit board those are some of my favorite videos I really wanted to get into circuit board repairs and what all the little components do and why and how LOL
