Great install. Was it difficult to remove the OEM water pump? I thought that it is one unit with the OEM heater. Is it correct, or it is a separate pump somewhere in the coolant circuit? Hi all, I installed a Webasto Thermotop 5 (see link...

Thanks for the reply re the timebase. I'll be doing some more testing this weekend. Can anyone advise how to post images (what file types, size limits etc) thanks

Interesting post. What is the timebase of the voltage rise graphs.?

Hi a small update, heavy snow here so not ideal for doing any testing on the HV side of things. On the low voltage, I've removed and checked the permanent supply fuse to the EVECU (this is actually the interior courtesy light supply fuse). Also the Supervisory Controller supply fuse (this is...

Another I've just checked is fuse number 4 from the fusebox by drivers right foot RHD cars. This fuse is described as a "starter" fuse and provides power to the EVECU. Anyhow it was good : another thing checked off.

In the UK Citroen offered 3 years warranty in the car and possibly 8 years on the battery. But I would like to know what component is faulty before entering the warranty rabbit hole.

Hi Kiev, Car was purchased new by me so I have all the history. When the problem started back December last year, I connected up Citroen/Peugeot Diagbox tool (offline version) and read all the ECUs. Only DTCs were P1A15 and U1113. The car has always had U1113, there is a note in Diagbox to...

With the Manual Service Disconnect plug removed, there should not be any be any circuit that would allow the HV bus capacitance to be charged, other than the high impedance of the test lead/meter. The impedance of the test lead and meter is 5MOhms 15pF so not anticipating any contactor damage...

From the battery service manual, coil resistance for positive and negative main traction battery contactors should be 33-39 ohms at 23 degrees C. I measured at about 3 degrees C.

Hi, I've got the same problem (P1A15) but on a 2017 CZero. There is a long thread under "batteries" http://myimiev.com/forum/viewtopic.php?f=23&t=4225&start=100 which might be worth a read. There is also a NHTSA bulletin on this which includes a long troubleshooting procedure, about 25...

Hi all, update on the troubleshooting for a P1A15 code error. I have checked the coil resistance of the 3 traction battery pack contactors (negative, precharge, mainpositive). All three coil resistances measured 33ohm. Is this a typical or good reading? It has at least proved that none of the...

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...

Hi, to answer the question of whether Hobrive works with post 2014 Czeros (if that question is outstanding), I'm the owner of a 2017 Czero and find Hobdrive paid app works OK. It can read and clear DTCs. regards G
