I am very sorry That I gave you a hard time understanding, the issue was not language related, It is related to my knowledge about this car.


i didn't realize the working car was 2018, it uses a different OBC and MCU than the ones that we have traced the schematics. And likely different control units too, such as EVECU, BMS, etc. The CAN PIDS are different such that the Canion App can't read the cell voltages, so there are many differences between 2012 and 2018 cars.

I noticed, they made lots of improvements. The old car showed 140 km range yesterday, I managed to go 50 with it and still has 70 km range...
With its original computer it showed 110 km...


But my point is that it would seem that the issue is not inside the pack since it went to READY with a different EVECU. Also it would seem that the MCU HV voltage measurement circuit is okay.

The problem came back, so it will be the MCU HV voltage measurement circuit. I think. I hope.

So there is this board, I read now carefully, what should I chack and change?



Good luck to you and hope you can find and repair the issue.

Thank you so much for your help!

So the P1A15 error is related to some failure in this circuit discussed here, viewtopic.php?f=23&t=4225&start=10#p39208

and here
viewtopic.php?f=23&t=4225&start=20#p39357

or on the hybrid isolation amplifier board (ISA board) here, viewtopic.php?f=23&t=4225&start=40#p40858

But i wouldn't recommend to add resistors such as mentioned--better to find the fault and replace the parts.

The Nihon website is not showing some of the previous links, but here is the circuit of the ISA board

good set of pictures here, viewtopic.php?f=23&t=4225&start=50#p40953

Hi everyone, I've just bought a 2012 Peugeot Ion as a non runner. Must start off by saying the forum has been very informative and I certainly understand the car a lot better now.

I've downloaded Hobdrive and used my elm327 obd adapter to read the fault codes. This has come up with P1A15. From reading previous posts I understand this relates to the car detecting a difference between the battery pack voltage and the capacitor voltage (the big black meiden one?). I'll attach the Hobdrive screenshots ASAP (these show that the capacitor is only at 2v).

If I reset the DTCs using Hobdrive, I do (occasionally) hear the contactors moving into position. I've only managed to get this to happen a couple of times though, as the DTC reappears very quickly. The rest of the time it's completely silent.

Have read from the previous posts that this issued may be due to some failed components on the PCB on the inverter. I'd really appreciate the group's thoughts on likely culprits- appreciate that this has probably been covered in previous posts, but I'm a bit of an EV novice (my Leaf hasn't needed anything done so far!)

Thanks Jason

i tried to summarize the likely causes in the previous post,
viewtopic.php?f=23&t=4225&p=41619#p41619

Follow the 3 links to read about each one; there is a schematic in the first one, good pictures of the hybrid board linked at the bottom of that post also.

The circuit board is in the bottom plenum of the MCU aka motor inverter.

Do you know the previous troubleshooting history, has the car been worked upon or molested by somebody, or is it intact. e.g. Has the pack or any control units been opened up and fiddled with?

Thanks Kiev, I will have a good look at those. I had read through the entire thread, but I think I must've been suffering from a touch of information overload by the time i got to the end...oops!

The service hatch cover in the boot/trunk had been removed and the dc-dc converter? (one with the 20 amp fuse) lid had been removed. The passenger seat and service hatch above the isolator switch had been removed.

I suspect that it hasn't been looked at by anyone specialist. There was reference made to problems with the 'condenser' when I bought it. Think this diagnosis could easily have been arrived at by any ICE garage with non specialist equipment, purely by extracting the DTCs and typing them into Google though!

Should add that I have fitted a brand new 12v battery.

Okay it figures that someone tried to figure it out, so no telling what they disconnected or replaced.

The box on the right is the MCU aka motor drive or inverter, it has the 20A fuse that is inline with the HV to and from the OBC (top plenum) and the DCDC Converter for charging the 12V aux battery in the lower plenum.

The condenser is in the MCU and it is not being charged up, either to the right voltage or not quickly enough, to make the EV-ECU under the rear seat happy.

There might be a problem with the CMUs as well, since the min and max cell voltages are reporting 0.39 V. But the total pack voltage seems fine (average of 4.063 VPC). I don't know if this is related to your main issue.

Having read through Kiev's suggested reading, I've set about trying to find someone local to test the components on the main and hybrid boards that have been found to be troublesome by others in the past. Not having too much joy with this so far though. Could anyone recommend a place in the UK (preferably Scotland) that would do this type of testing and replacement work?

Simon (username: DBMandrake) is the smartest guy in Scotland for solving problems and he knows how to open a pack and change cells because he did it. There is an EV forum at SpeakEV with lots of UK and EU folks, that may be able to help you find somebody local.
