Renault MEGANE III SPANNER LIGHT/ NO DTCS

[gomarota]

Im totally desperated with this, im more than 2 months with this car, im ready to pay whatever, is police car and i need to solve it, thanks

here is the full comment:


car came with spanner light, and "revisar vehiculo" like "inspect vehicle", car is running fine


no dtcs in any module, just in


MULTIMEDIA INTERFACE:
dtc930913 wake up signal C0


UPC:
DTC921114 - UPC constant power supply circuit




i saw this post i saw one post in internet, says something about cable between upc and bdu


i had same problem


i found in UPC actual values input/ouput BDU : 15volts


i found bloken wire B1PC (from bdu to upc), i resoldered it
now in upc input bdu is like 12,4 vand output bdu 12,4 v so its ok


but now in UPC now says code


dtc922a13 battery disconnection unit control circuit


and i cannot sort spanner light and inspect vehicle




i changed BDU and UPC, i code with renolink all the fileds, and VIN too


can i disable it or something?




also i tried to make external connection, my car has 1 cable in 3 plug connector from bdu to UPD


i rewired the other 2 cables, my car doesnt has installation but im upset


still doesnt sorted

So not knowing much about that system. That broke wire go back to it and look for more next to it

[gomarota]

yes friend i also thought that, but i checked all the wiring and all is fine. i spent so many hours and days

Hi Gomarota,
I see you're desperate!
Ok, you're talking about B1PC that should be BP1C broken wire.

Sorry i do not understand exactly what the problem is: Car runs but you can't reset service light, is it correct?
Maybe it could be easier to explain in spanish? Do you want to send me P.M.?
Have you Renault CLIP?

Behind the battery there is a power off unit. disassemble it or replace it. Check the fuse on the side.

Gomarota said this part (BDU) has already been replaced...

Is it possible pin on plug gone rusty

Is it possible pin on plug gone rusty

What did you understand , do you think car starts and the problem is only on service alert or what?...

[gomarota]

fuse on side of bdu is fine, B1PC has 12 volts going from bdu to upc

hi.Have you used the repair tips that canclip offers? a book is opened from the right on the screen, this is a repair technique

[Louislesinge]

Ok,
Now "inspect vehicule" is turned Off?
You mean you have some DTC on ECUs but no message about them on the dash?
So when you go to menu service on the dash, how many kilometers to next oil service and full service?
Maybe you can post a picture of this message.
How did you manage the autoconfiguaration of the new UPC, have you Reprog DVD to do it with Clip?

Thanks already solved by dealer update
