Hi. I'am not an expert in disabling START/STOP function but I may suggest the way. IMHO it's may do a job. |

do some people say you can disable SS by just removing the extra cable on the 12v battery under the bonnet
If you get SS error light on board you can always extinguish it by coding it out on the cluster
also I dont know what year your ph2 is if over 2019 (but I think it would be called clio5 then) but if it is you will have a security gateway firewall on the OBD2 that you have to unlock with a token from renault before making any adjustments on DDT4ALL |

I suppose it is a battery current sensor. Removing it you will broke SOH procedure and may damage or get drained the battery one day |

ah right thanks, what is SOH - state of health? |

@AndyIreland yes It is. The car ECUs have quite complex algorithm of battery state assessment and the battery current sensor is one of main sensors for this. |

To be honest, i didn't get what you mean :) I know that start-stop comes alive provided some conditions are met in the car . For example engine temperature (it won't start-stop when engine is still cold) , so it might be possible to set this temperature setting so high as to render start/stop useless as this temperature might never be met ...this is just a guess ... |

Hi Andy, i will be trying to deactivate it through DDT4ALL ... based on data available, i think it will be quite safe and easy to do but i would have felt better if i found someone who did it already and used a specific ecu/parameter to do it. My Clio is a X98ph2 - Clio IV Ph2 (this is the model in ddt4all) which is the facelifted Clio iv produced 2016-2019 (it is not firewalled or sth) |

yeah - just make sure you choose the correct ecu(s) to do it. do a search for particular right ECU's in your car with the magnifying glass in DDT4ALL |

Simply install a jumper on the hood open sensor connector. |

well, to be honest i would like to get a bit involved with ddt4all as there a few other things i might change if start/stop project goes well ...so, generally disabling start/stop feature is not the main/only issue but disabling it properly with ddt4all is :) . In other renault cars' videos and instructions online, it appears as easy as four clicks (i mean it looks easier than the bonnet sensor that you proposed which is also a correct solution to deactivate ss) . What puzzles me is which of the above three commands would be better/safer to choose ... |

i haven't yet understood what green and red ECUs mean ... i mean if the command i want to change is in a ECU listed as red (after searching with the magnifying glass) , should i mess with it or not ? So far, i have studied almost all ecus in demo mode (complete tree - all screens etc) but i have zero experience of connected mode as i am waiting for reliable hardware - my mini and old blue ELM327 clone doesn't qualify as such). Anyway, after posting this, i found this thread #728 and from what i understand, my above option No 2 (disabling through UPC-EMM) didn't work for this user with a ph2 clio iv . So for the time being, my two options will be no 1 and no 3 :) |

in found ecu's if they are in RED then it means that DDT has found a ECU , but its not the one it has expected , so you can make changes but be extra careful with your changing of parameters and take extra caution just in case it bricks the ECU software... I mean thats what I have always taken the red ones to be - but that does not mean to say I have not changed parameters on those red ones , because I have and its been fine with me ... (so far! LOL) |

No problem. Sorry for my bad english. I'll try to explain in other words. END_CLUTCH_USED_FOR_AUTOSTART_CF In your case it may be different set of parameters and it's why I mentioned your VIN in my first message |

Hi Shrlnm and many thanks for your input ... i understand what you mean . It makes sense that start stop is connected with clima as the operation of clima, might delay/postpone or even inhibit the start/stop function (meaning that if you have ambient temperature of 35 degrees and you set clima at 20 degrees, the compressor will be working at 100% thus inhibiting the SS function to operate until desired temperature is reached or almost reached) ... on the other hand, i have seen a lot of users canceling the SS without having (or without reporting) any issues or abnormalities on other systems... anyway my VIN , in case you can source sth more specific for my car, is VF15RBJ0D57602094 ...also, please do check the above three possible solutions and let me know which one appears more harmless than the others (for some reason, my first choice would be solution no 3 (through Injection ECU) :) |

@Trickykid1978 For your VIN the difference is also in three ECUs For disabling s/s Cluster_X98_X87_X82_xHA_X98ph2_X87ph2_v7.4_20160112T110528.xml BCM_T4_VS_DDT_22_20160531T140853.xml ClimBoxGen3-v6.3_20161121T160703.xml |

So you have already tried through EMM ? |

Yes, unfortunately it does nothing at all... |

Hello again, Trickykid1978...can you give us any updates on this one?? Is your car still running well?? no side effects?? thanx |

To be exact, i have a Renault Clio IV - 2018 (ph2 model) - dci - 1.5 - 90hp with EDC gearbox. |

OK, mine is 2013 captur dci 90 hp...it is the same engine, I guess. But it is five years older, maybe that´s the reason my ECU´s don´t behave in the same way...thanx anyway for all your help and posting all your experience here |

I think you should first identify the actual ecu injection in your car (maybe scan car with PYREN and see which injection ecu is identified there, i mean the exact xml) . Then you can load up this specific ecu in ddt4all (from the drop down menu, not the magnifying glass) and see if it is actually returning live data from car. This is what i did and despite the risk involved, it worked in my car ... It wouldn't be possible for my start-stop to be deactivated if i only worked with green ecus (or even red for that matter as the injection ecu was not even found in my car when i scanned it with ddt4all) |

OK, just tried again and this injection ecu shows "no data" on my car, couldn´t do anything. So I guess the only option left I have is try some of the parameters of the UPC unit. Does anybody know what these ones stand for?? , especially "Nxx_EMM_SAC_CF" and "Nxx_StopStart_ESM_FIh_CF" (I have no idea) Nxx_EMM_SAC_CF ?? ;1 I´d like to try and understand as much as possible for avoiding risks...thanks for your help |

By any chance does anybody have DTC 926755 after disabling Stop-start?? |

This is error that's not configured.... activate and ready. It's Not allowed 🚫 |

This code says that the SS System have to activate.. !!!!! |

|
Yes, but the question is...why does disabling stop-start in ECM/injection unit triggers no error and on the contrary doing it on USM/EMM unit does trigger the error? |
Beta Was this translation helpful? Give feedback.
-
|
Because the USM look for the status and configuration. Is the status deactivated...than happened the error. |

Hello everybody,
A complete newbie here ... while waiting for a reliable ELM to arrive (i bought a USB and a WIFI ELM327, both with PIC18F25K80 chips) , i started getting familiar with DDT4ALL in demo mode (i am using DDT4ALL Version 5.5.0 with a 2021 database, loading 3618 ECUs in total) . The first task as soon as i get connected, would be to deactivate the start/stop feature completely and for this reason, i watched tons of videos, read forum threads, etc . So far, i have found the following parameters that can disable start/stop but i am looking for the one that i will finally choose. Have you tried any of these solutions and which one would you choose just to remain on the safe side of things ? (the third solution comes from a user in Turkey who has posted a video in youtube explaining why this solution is better as it won't generate a SS signal in the dashboard saying No available etc)
