I suspect that as the safety system deployed the airbags, it has also cut the HV battery inverter relay incase any of the battery packs have sustained damage. Your going to have to get the vehicle recovered.

Hope you and everyone involved in the accident is OK.

 

Thanks for the prompt reply. I bought it like this from copart. Do you know the location of HV battery inverter relay location.

 

The inverter is usually connected to main battery pack underneath the car. Please be aware that these vehicles operate on a 400volt system which has enough amps to kill you. They are not designed to be worked on by anyone other than a qualified EV mechanic. I would advise getting in touch with a HEVRA registered garage for assistance.

 

Car is in park mode. I cleared all the faults. But still won't start.

 

I would have thought that if it won't start, there must be a reason, and that would cause a fault code to appear?
After being deployed, the airbags may have to be replaced or bypassed.

 

Whenever there is a crash the airbag module sets an error who can prevent the car from starting. If it is a heavy crash a different error is set that can only be cleared by a special proceadure on the dealership.

You can also check the pyrotecnic fuse, it is normally detonated on heavy crashes to quickly disconect the battery and will need to be replaced aftewards
In any case you should be able to move it out of park to N.

 

There is a reason why BEVs do that.

it's so you have to take out the battery pack and all the HV electronics for a safety inspection.

If you bought a written off BEV and have to come to an internet forum to look for inspiration, I think you've made an unwise purchase. Sell it on as it is.

Why do you think insurance on BEVs is sky high? Because they basically have to be totally dismantled and safety inspected after each 'bump'.

Welcome to the Brave New World of BEVs.

 

Makes sense. I don't like them at all. It's due to work requirement I had to make a move. But I think I need to stay away from these loo.

 

Probably a Pyrofuse inside the battery pack that has blown.

Your standard faultcode reader may not be able to talk to the battery electronics.

 

does any1 has picture of pyro fuse, also part number

 

Either pyrofuse on the battery has blown - if the car has one.
Or crash lockout in ECU.

Either way you should probably not be messing around with this unless you know what you are doing with electric vehicles.

 

Exactly as @Aragorn has said, pyro fuse has blown. Absolutely do not in any way, shape, or form, do a DIY fix - it's lethal working inside the battery compartment without the proper PPE and training - DO NOT EVEN THINK ABOUT DOING IT.

400V DC is absolutely lethal, and there WILL be 400V DC present on exposed terminals adjacent to the pyro fuse.

Ignore the above if you are a qualified EV tech with the appropriate PPE and training. The PPE includes double insulated gauntlets, leather over-gauntlets, flash protection and a helmet with a certified flash protection face shield. You also need VDE rated footwear and VDE rated mats, together with approved test gear to dead test the connections you are working with, plus a 400V DC proving unit to be sure your dead tester is working.

 

Where are you based?

 

Luton

 

It’s popped its pyro. Amongst other things which go pop. Take it to a specialist, to replace it and reset the various ECUs which have gone into crash / protection mode.

 

I think srs ecu is locked

 

I doubt the SRS module being locked would stop the car driving. This is probably a powertrain or battery ECU locked out after airbag detonation - but as others have said you don't seem to have the experience to be messing around with a 400V vehicle so I strongly echo @simcity, it needs a professional.

 

Nothing to do with the SRS, the pyro fuse will have popped for sure, as that explodes and opens the 400V DC from inside the battery pack as soon as the airbags operate.

 

SRS airbag ECU sends crash signal to other computers on the bus.

If it can be reset or not - does not matter. Has to come out anyway.

Only after fixing airbag system you can pass to next step - checking HV components - replacing any blown parts etc

After that a special procedure to re-enable the HV operation is needed.

It's very individual, and differs from manufacturer to manufacturer.

 

wonder how poster got on with car

 

Sorry I sold it as it was

 

Hello kool,
Did you get any help ? Am also getting the same problem

 

do u know where is the pyro fuse ?

 

Yes. In the Corsa-e and Mokka-e it's located INSIDE the traction battery pack. So you'd have to 1 remove the battery 2 split the battery pack to get access to it. Highly dangerous and requiring specialised training/ equipment.
If you really want to do this, I'd suggest it'd be easier and cheaper to simply drop the original battery and replace it with a used pack from a scrapped vehicle. But again specialised handling of a high voltage battery is required.

 

And your reasoning?

 

In Peugeot EVs, the high-voltage (HV) protection system in case of a collision functions a bit differently compared to Tesla and many other modern EVs. This system is also used in models like the Mokka, DS, Corsa, e-208, and e-2008, as they share similar components.
In a Peugeot, when a collision occurs, the SRS Module sends a hard-coded "collision detected" signal to the TB ECU. This code, often something like P1B28, triggers the HV protection system to disable the HV Interlock Loop, cutting power to the transmission and motor.
In contrast, brands like Tesla, Mercedes, and Ford use a pyro fuse in such situations. When triggered, this fuse detonates, physically disconnecting the contactors and HVILs to shut down the HV system entirely.

 

Hi Matt, that means to start the car all you have to do is to remove the crash data from airbag Ecu ? Thanks

 

Hi, I’ve got the same problem. Are you able to help or local to Surrey?

 

Hi crashed e208 locked hardware and wondered if you could help. 2024 e208 gt . Only seatbelts went off ,I have reset srs ecu. Got code of hv battery internal switch open and won't perform reactivation. Dash says energy economy mode and nothing works , lights windows locks etc .

 

Hi, Did you manage to start the car ?

 

Hi guys how did you get on with the HV lockout in the Peugeot? I do a fair bit of salvage and did a Porsche taycan last year with blown airbags and was easy to reset the HV battery once I got the software from an online forum, I’m now thinking of buying an electric damaged Peugeot 2008 for the missus but thought I’d check to see what the reset procedure is on pugs first as I can’t be arsed dripping the battery and splitting it to replace a pyro or what ever.

Did you get a knock off copy of PIWIS or something else?

 

Yeah piwis 3

 

What forum was that from?
