Hi
This little Modus came to me half dismantled due to some else being trying to resolve a non starting problem.
The cluster would not light up, no cracking and no communication with several modules, including EPS , ECU, Airbags etc...
Follow me on this video to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!
Tricky diagnosing a vehicle all apart without knowing the full history of replaced parts etc, but great job as always Luis another happy customer 👍👍👍
Indeed!
Thank you for watching and for your comment Igor!
This problem are very common ,they started on Megane 2 as from 2003-2008. its the upc which gets water inside,ive replaced over 70 of these.u either get corrosion inside or burnt connecion.. om megane 3 its fine till now. great job like first time issue ,have to start from the basic to find the issue. it happened to me back in 2005 when i was still working for renault as a technical cordinator.,and i started at 5pm finished 11pm. the rest was easy. no power chk UPC and replace. but your work procedure was like a pro technician.,hats off
😊
Coming from a technician I really appreciate you comment!
I am actually just working on another one which although there is no signs of water ingress, it looks like is suffering from an upc failure....
Thank you for watching and for your comment!
whats does upc stand for read its a under bonnet switching unit ???
Okay i have question Modus 2005 1.5dci - The engine is rolling but not starting we thought it was the injectors or the pimp but it got good bar’s of pressure and wont start . Just rolling on starter and wont start. We check everything! I mean everything. It have fuel , it doesn’t save checks (errors) give us a way / path to what to look for
Check live data when cranking...
Do a relative compression test...
See if that shows anything...
Thank you for watching!
Thank you Luis bought the 4 pin micro relay online fitted it and touch wood it has been great. I hope my comment is not removed again!

Thank you , have a great weekend to everyone.
hi Luis, great job so far, I wanted your advice on my 1.5 dci mod. it doesn't like to turn and won't start. also it doesn't work. placed on the tester shows that all codes are open. I don't know what that means, but supposedly the computer in the PSP activated the vehicle's immobilizer. I would like to ask you for advice on what to do.
What this video carefully...

Once again a nice step through the trouble shooting process. Top job..
Thanks!

Could you help me? I have a clio mk3. It uses the same fusebox in your video. I'm getting a low battery and battey symbol on my dash. Voltage reading is 13.70 engine on. Do you know if the alt sense wire goes to fusebox? I belive inside the fusebox is a pcb with 8 smaller relays soldered to the pcb. Do you know if one of the relays on the pcb is responsible for alt charging message at all? The sense wire on the alt is reading 2v
The program that you are using to orginal. Nice video
The state of some of the cars you've had recently from other's attempts at repairs has been shocking. Makes fault finding even more difficult but glad you managed to fix it. Not sure you've covered it in your other videos but for the diyer like myself it would be useful to know what the acronyms mean for the different modules as they seem to vary per manufacturer. Just a quick google shows UCH, BCM, BSI, BSM all for one box! Also you mentioned this is the "same" module for Micras and I think I've read that k12's can have issues with these modules. As my mum and brother both have old k12s then are there any preventative measures that can be taken to stop the failure of them / make sure there isn't any water ingress etc.? My brother also has the keyless entry/start which I'm very nervous about that going wrong as it will probably be a write off. Also beige interiors never age well.
Hi Rob...
Yes, the acronyms vary from manufacturers... experience or a quick Google search most times will help you finding what they are...
Yes, this UPC module is also fitted on the Nissan's... as you might have seen, this one had signs of water...
I think keeping the drains cleared etc will help...
Don't stress untill you actually have a problem... lol
I know is easier to say than do...😉

It is French... but stands for something like under bonnet control unit...

how to remove renault modus check gearbox warning sign?
Just started watching this video. Everyone must be screaming from the start "What about the UPC". Flicked forward a bit, maybe it's not recognised because the other UPC is from a K12 Micra? (Black sticker usually = Nissan). These have basic IMMO in as well. No mention of cloning by copying the 93c46? There are 2 types of bottom PCB in the UPC as well. Not compatible either.

I will get there...

Not an easy diagnosis with the car pulled apart and incorrect parts and someone already having messed with it.
I always wondered about parts interchangeability between Renault and Nissan. Actually from what i have seen on this channel it doesn't seem like Renault took lessons on wiring and electronics from Nissan. They still seem kind of poor.
Indeed... still a bit if work to do by improving their wiring, module location and sealing!
Thank you for watching and for your comment!
Upc that's what I want to see
LOL 😂

"Where is my mouth", kkkkk
honestly who buys these cars, renault haven't been good since they introduced their stupid card key

Those cards are the love and hate of many people...
