Renault Modus 1.5dci not starting, ECU no communication. Fault finding and repair.

Consider to support my channel and all the hard work put into it at / lmautorepairs
Thank you
Hi
This little Modus came to me as a non runner...
Turn the ignition on and the radiator fan would kick in, immo light on/flashing and no crank etc...
When plugged the scanner, was no communications with the engine ECU...
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!

I have 2-3 monts ago one modus with exactly the same behavior. Intermittently no crank no start, immo ligh on, no com, fan on... I saw that probably is missing power suply on engine ecu. So I look at diagrams and backpin engine ecu connector first and boom 3 volts and fluctuating up and down. So I find that same relay is bad. This relays are garbage. Funy is that, in my case is also missing a vin number and someone was there before me. When I gave the car back to the custumer, custumer told me that previus guy replace engine ecu. God job Luis as always and thank you for the video.

Greetings from South Africa - I got someone coming in the morning to have a look and I am going to give him pointers from this video. I bought a non-runner. Fan kicks in when you switch it on, engine light ofcourse, cranks once then does not until a minute or so when it allows you to retry. No glow plug light as well. It does pump diesel though. Weird thing though when you try to crank it only cranks for like 1 second then cuts out. Anyway I am hoping for the best when the guy comes in and I am also hoping I can solve the issue before tomorrow because I have a feeling this guy is going to charge me big time and not find the issue straight away but this video helps

[@timmehlittleloud2251]

The difference in the relays is that one has an internal protection diode. If memory serves, on this type of fusebox, the +ve feed to the relay coil is the opposite way round in 1 or 2 of the sockets. So if you put the relay with the diode in that particular socket the +ve feed to the relay coil will be switched to GND through the diode and not the coil - BOOM! Superb design by Renault. In the factory manual it does say we are not supposed to change faulty relays but replace the UPC. Normally the UPC rots to death on these anyway. I've seen 2 types of PCB and they are not interchangeable if trying to repair. With the right PCB swapping the 93c46 from old to new swaps the config without issue. I get a lot of SMD transistor faults on these as well.

Great video that I wish was around in early 2018! Had the almost the exact same issue with my 2008 Megane 1.5 dci, apart from it wasn't intermittent, just one morning it wouldn't start but would turn on the fan. Couldnt find any info at the time so had a car electrician come out who had a poke around and diagnosed the issue, saying the ECU wasn't getting any power. He didnt fix it but said 'This white cable needs power' which I took literally and essentially hotwired to the battery with a fuse and a switch in the cabin, obviously I know nothing about car electrics but its worked every since - providing i remember to turn off the cabin switch! I've always thought it was odd that a single cable broken but if your issue is the same as mine I wonder if I'm just bipassing a bad relay. What was the relay you replaced? And was it just in the fuse box? Many thanks, Nathan

[@gilgameshismist]

Owner (or even previous owner) probably paid through the nose to get a new ECU placed without it solving the problem. I often saw these types of vehicles later sold because the owner put a lot of money in it and the problem was never fixed, sometimes with really minor causes: semi-loose earth line, a cold soldering in a module, or even a relay with it's own mind. Not every shop has someone like Luis sadly!

Excellent video Luis, I like the logical way you work through problems. Could you suggest a fix or point me in the right direction to solve an intermittent starting fault on my sisters 2004 Modus 1.5Dci, K9K engine. The car has never failed to start, but it almost never starts first turn of the key, the engine usually starts after 2 to 3 attempts, on some occasions it can take 10 plus attempts to start the engine, temperature and and ambient air temperature don't make any difference, the car has been to a Diesel fuel system specialist that told us nothing is wrong with the fuel system high or low pressure delivery to the injectors, the injector leak back test was normal for a engine with 120,000 miles on it, I have yet to find a solution. Any help you might be able to give would be very appreciated, thanks for all your videos they are a big help and entertaining 👍.

Hi, My modus has a similar problem. After a bit of driving all the warning lights flash up and I lose use of the headlights and indicators (and probably others) and then that usually stops after a minute or two and instead it flashes up the spanner and both airbag warnings. If I stop the car and restart the screens load up normal again but it will happen again after a bit of driving. The garage have no idea what it could be. I had the battery replaced but it hasn't helped. Do you think it could be a similar issue to yours? Also, do you know where the earth cables are? Someone said I should check those.

@@GOFIVEK8T pin 30 is 12V input voltage that makes solenoid open when needed and send the 12V to 87 pin so if you have a relay that you do not know if it is working or not the quickest test is to put a bypass between 30 and 87 this way you will give 12V to the rest of the circuit controlled by that relay.

maybe a burn contact inside relay

You have not watched the entire video...😉

[@rollinhand4750]

[@LMAutoRepairs]

And I did... 😋 Thank you for watching and for your comment!

Hello I have a question about bsi, can i contact you by email

[@LMAutoRepairs]

Just ask here... 👍

[@veecooper6033]

Please can you tell me the relay number.

[@LMAutoRepairs]

I can't remember the number... but I believe I showed its position in the video... 👍👍👍

[@veecooper6033]

Thank you for your speedy reply. You did but they seem to want to know the number. Any idea how else to find the part?

[@LMAutoRepairs]

Do you have the old one?

[@veecooper6033]

I haven’t removed it yet your video was so helpful I had hoped I could get one without doing that. But it seems now that is what I will have to do. Thank you.

Hello, if i could hire you to check a problem in my car, where can i find an email or contact number? and if its possible, where about you are? thank you.

Look on the side of the relay some have diode/zener in it. typical Renault.
